BRESSER Messier MC-152/2250 Hexafoc EXOS-2 GOTO

Die BRESSER EXOS 2 Goto Montierung

von Jochen Fehmer
2016-12-15

Mein neustes Testobjekt ist die BRESSER EXOS 2 Goto Montierung. Nun ja, in der Astronomie- Szene ist sie nicht gerade als die Montierung schlechthin bekannt und die Meinungen gehen weit auseinander.

Also ab ins Lager und eine BRESSER EXOS 2 Goto auf die Sackkarre und ins Auto damit. Mir fiel auf, die Dimensionen des Kartons sind echt übersichtlich, kein langer schwerer wie ich es von anderen Montierungen gewohnt bin. Es sei gesagt, es war keine überprüfte oder eine ausgesuchte, es war eine von der Stange oder besser gesagt vom Regal.

Zuhause angekommen und gestärkt von einem Abendessen machte ich mich ans Werk.

BRESSER EXOS 2 GOTO mit EXPLORE SCIENTIFIC AR102
BRESSER Montierung EXOS 2 GOTO

Ich packte die Montierung im warmen Wintergarten aus, denn draußen war es schon sehr kalt, minus 4 Grad. Als erstes das Stativ. Es ist aus Stahlrohr, leicht und mit zwei Feststellschrauben pro Fuß…das finde ich schon einmal gut. Trotz des leichten Gewichts scheint es sehr stabil zu sein. Dann kam der Montierungskopf; die Motorenabdeckungen sind aus Kunststoff. Egal, wenigstens sind die Zahnräder und die Kugellager einigermaßen vor Staub und Feuchtigkeit geschützt. Auch da fiel mir auf, dass die Montierung sehr leicht ist. Die Montierung auf das Stativ zu schrauben ist sehr einfach, eine große Drehstange erleichtert das ungemein. Gute Idee,wenn es draußen nicht gerade warm ist. Dann die Gewindestange an die Montierung geschraubt. Ein Gewicht ist im Lieferumfang enthalten, dass auf die Stange geschoben und fest gezogen. Handbox angeschlossen und das DEC. Kabel installiert. Fertig. Die BRESSER EXOS 2 GOTO Montierung macht so einen guten Eindruck, alle Schrauben sind groß genug um auch mit Handschuhen bei niedrigen Temperaturen arbeiten zu können. Allein vom Aussehen gefällt sie mir sehr gut.

Aber, gut aussehen reicht nicht. Leider suchte ich vergeblich nach einer Polsucherbeleuchtung. Diese muss als Zubehör gekauft werden. Dafür bekommt sie keinen Applaus. Es geht zwar auch ohne, aber mit der genauen Einordnung fällt und steht die Beobachtungsnacht. Schade.

Ich habe das mitgelieferte Batteriefach mit Batterien gefüllt. Ich wollte so damit arbeiten wie sie ausgeliefert wird. Ein Netzteil kann man als Zubehör erwerben.

Auf geht’s, Montierung angestellt. Als erstes fiel mir das sehr große Display der Handbox auf. Sehr angenehm die Infos zu lesen. Keine Laufschrift sondern stehende Buchstaben. Die Umstellung auf unsere deutsche Sprache ist kein Problem. Nur dass die Schrift auf einmal viel größer wurde….warum dieses? Keine Ahnung, eventuell sind viele Deutsche kurzsichtig. Die Zeit und das Datum musste ich nicht mehr eingeben, bei Bresser werden die Montierungen mit dem Goto versehen, so dass alles schon eingegeben wurde. Auch hier ist zu beachten wenn es eingegeben werden muss, erst das Jahr, Monat und dann den Tag. Nun zum Standort: Vorgegeben sind etliche Länder und Städte. Da es aber keine Updates mehr gibt kann man eigentlich sofort damit beginnen seinen eigenen Wohnort einzugeben. Dafür einmal nach unten mit den Pfeiltasten.

Die Zahnräder hinter der Abdeckung

Längen,- und Breitengrad eingeben. ( Wenn man den nicht weiß einfach im Internet oder Handy gucken ), Zeitzone hier in Deutschland ist 01. Wenn alles eingegeben ist bestätigen und das ist erledigt. Jedes Mal wenn man nun die Montierung ein schaltet nur noch auf Benutzerstandort gehen und fertig. (interne Batterie). Ich hatte für die erste gemeinsame Nacht mir folgendes vorgenommen.

Doppelschiene und 200 mm Canon Objektiv mit einer Canon EOS 6 D und 8x50 Sucher mit einer ASI ZWO 120 Guiding mit PHD2. Normalerweise sollte man die Montierung in DEC. und RA. auf vorgegebenen Pfeile stellen, dieses wollte ich aber nicht. Ging ja auch nicht, da ich mit einer Doppelschiene arbeiten wollte. Also ausgerichtet und angeschaltet. Ich wollte eine 3 Sterne Ausrichtung machen. Machte ich dann auch, einfach der Sternvorschläge ohne Widerworte folgen. (Wie in einer guten Ehe, keine Widerworte) Drei Sterne durch und fertig. Ich habe keine Ahnung ob das richtig war, schließlich war ich noch im warmen Wintergarten.

Zum Schluss sollte sie auf Home Position fahren, das tat sie auch mit der Querstellung meiner Ausrüstung. Natürlich habe ich vorher das Gewicht der Kamera, Objektiv etc. genau ausgependelt. Das ist sehr wichtig, die Gewichtsverteilung sollte schon passen. Dann ging es raus in die Dunkelheit und in die Kälte.

Die BRESSER EXOS 2 Goto Montierung grob nach Norden ausgerichtet. Nun die Montierung mittels Dosenlibelle auf dem Stativ in Waage gebracht. Dann den Deckel des Polsuchers abgezogen, den Schraubdeckel entfernt. Da keine Polsucherbeleuchtung dabei war habe ich eine Laptop Lampe genommen. Ist eine kleine LED Leuchte mit Klemme und flexiblen Arm…ist zwar kein Rotlicht, geht aber auch. Es geht auch mit der Hand box! In der Hand box vorne ist ein Rotlicht eingebaut mit verschiedenen Helligkeitsstufen. Ohne Probleme reicht die Länge des Kabels aus um in die Öffnung des Polsuchers zu leuchten. Hab ich ausprobiert, klappt. Bei der BRESSER EXOS 2 GOTO ist in der Mitte ein Strich und dort ein Kreis. Da steht Polaris. Es gibt zahlreiche APPs für das Handy. Unter anderem auch die APP- Polarfinder. Diese benutze ich immer. Automatisch habe ich die Position von Polaris. Bitte positionieren Sie den Polarstern auf den Kreis, nicht in dem Kreis. Sie können sicher sein, es passt. Ohne viel Mühe ist das erledigt.

Dann habe ich die Kamera angeschlossen und den Laptop gestartet. Die Scharfstellung ist schon eine heikle Sache. Ich nehme immer den Polarstern. Bis jetzt hat es immer geklappt. Es wäre schade, wenn die ganzen Aufnahmen unscharf oder die Sterne Donuts gleichen, die Zeit sollte man sich nehmen. Zahlt sich später aus. 

M 45

Foto von Jörg Ortmann aus Hamm-Pelkum , 5.12.2016 (M 45 mit der BRESSER EXOS 2 GOTO, 24x300 Sek., ISO 400 , Canon EOS 1000 Da.)

Die BRESSER EXOS 2 Goto Montierung sollte beim ersten einrichten nur zwei Sterne anfahren, erster Stern war fast in der Mitte des Kameradisplays. Okay, ich gebe zu es war ja das Canon 70-200 mm, F4 Objektiv. Da wäre es sehr traurig wenn ich den nicht gesehen hätte, oder? Beim zweiten Stern viel ich aus den Wolken, die Montierung schlug den Polarstern vor. Alles klar! Doch ich zentrierte unsern Nordstern und bestätigte die Auswahl der Montierung. Da war ich mal gespannt. Ich scrollte auf der Handbox auf den Menüpunkt Messier Objekte und tippte die Zahlen 4 und 5 ein. Die Plejaden sollten es werden, das erste Objekt welches jemals die Montierung angefahren hat…..ein Stück Geschichte. Auf ging’s, sehr langsam und ruhig fuhr die BRESSER EXOS 2 Goto den Himmel ab. Das Motorengeräusch ist ruhig, es wird keinen Ärger mit Nachbarn geben. Und dann war meine Überraschung sehr groß, mittig strahlten die sieben Schwestern im Display der Canon 6D Kamera. Der Adler ist gelandet! Oha, das ist doch mal was, innerliche Freude machte sich breit. Doch wie wird es weitergehen? Also, M 31 die Andromeda Galaxie….ist ja nicht weit weg, 31 in dem Menüpunkt Messier Objekte eingetippt und bestätigt. Und siehe da, M 31 in der Mitte. Dann wurde ich übermütig, Deneb im Sternmenü eingegeben, Mittig. Vega eingegeben, wieder mittig. Warum fragte ich mich, denn innerlich hatte ich mich auf Frust eingestellt. Okay, sie wollte es wissen. Ab zu den Plejaden. Eine Minute Belichtung ohne Guiding. Ergebnis: Punktförmige Sterne. 120 Sekunden eingegeben und Belichtung gestartet.

Kurz in die Küche gegangen und einen Kaffee geholt. Da hatten die Sterne leichte Tropfen. Aber gut. Jetzt wollte ich mal loslegen mit der Fotografie. Ich benutzte ein 9x50 Sucher mit einer ZWO ASI 120. APT auf meinem Laptop unterstützt die Astrofotografie. Im Display von APT stellte ich M 45 nochmal richtig scharf, durch die Zoom Funktion eine tolle Sache.

Leider merkte ich die Himmelqualität lies langsam aber sicher nach. Feuchtigkeit machte sich breit und das Seeing wurde von spitze zu überhaupt nicht mehr spitze! Aber egal, es gab aber noch ein paar Einstellungen die ich machen sollte und zwar die Guiding Geschwindigkeit bei der BRESSER EXOS 2 Goto auf 0,500 ändern. Bei PHD habe ich die Kalibrierungsschritte auf 1000 reduziert. Das waren nur grobe Änderungen, ein Feintuning wird es erst bei den nächsten Tests geben. Nun habe ich die BRESSER EXOS 2 Goto mit meinem Laptop verbunden. Ich habe mir einen passenden Stern ausgesucht und die beiden Sachen sich einrichten lassen. Fertig. Die Ausschläge der Korrektur hielten sich in Grenzen. Also gut, dachte ich und wechselte in mein Belichtungsprogram. Ich stellte ISO 400 ein, 180 Sekunden Belichtungszeit und insgesamt sollten 30 Aufnahmen gemacht werden, also 2 Stunden. Ich startete die Aufnahmen. Ich war gespannt, denn man kann live die Korrekturen des Guiders sehen. 0,30 -0,85, in dem Bereich lagen die Zahlen. Das ist jetzt echt völlig in Ordnung, obwohl ich von anderen Montierungen ganz andere Zahlen gewohnt war.

M31

M31, die Andromeda Galaxie. Aufgenommen mit einer Canon EOS 6 D und der BRESSER EXOS 2 GOTO Montierung. ISO 400/30x120 Sek.

Dann war das erste Foto fertig. Ich vergrößerte es auf dem Laptop, und man staune, die Sterne waren Punkte. Dann wurde es Zeit sich ein wenig aufzuwärmen und ich ging ins Haus. (Rentner Astrofotografie, bin halt über 50!) Nach knapp 2 Stunden ging ich raus in die dunkle, kalte Nacht um die Aufnahmen etc. zu kontrollieren. Alles noch in Ordnung. Die Schuhsohlenwärmer aus dem Baumarkt hielten das Objektiv und den Sucher Tau,- und Eisfrei. Ich entschied mich nun mit dem Sigma 120-400 mm mit F5,6 auf die Andromeda Galaxie zu schwenken. Objektiv gewechselt und dann M 31 eingegeben. Unsere Nachbargalaxie war mittig im Display der Kamera.

Anschlussbox

Die Anschlussbox der BRESSER EXOS 2 GOTO Montierung. Von links nach rechts: ST4 für Auto-Guider zum Nachführen von länger belichteten Aufnahmen, Strom, An,-Ausschalter, Hand box und Stecker für DEC.-Achse.

Das Guiding musste ich neu starten, es wollte mit der alten Einstellung nicht mehr. Das dauerte aber nicht lang und die Belichtungen konnten beginnen. Die Tests mit „richtigen“ Teleskopen werden in den nächsten Wochen folgen. Auch diese Belichtungsreihe klappte auf Anhieb. Um drei Uhr rum war es dann auch gut. Die Batterien waren noch nicht am Ende, ich aber. Alles aus stellen, wegstellen und müde ins Bett fallen.

FAZIT DES ERSTEN TESTS MIT DER BRESSER EXOS 2 GOTO

Im Großen und Ganzen bin ich positiv überrascht. Sie hat Ihre erste Testnacht sehr gut überstanden. Sie hat das gemacht was sie sollte und wofür sie entwickelt, gebaut und verkauft wird. Alleine das Piepsen der Hand box nervt ein wenig. Kann man nicht abschalten, wenn es zu viel wird einfach Gewebeband draufkleben. Mit der Hand box muss ich mich noch ein wenig beschäftigen, wie eigentlich mit der ganzen Montierung. Als ein richtiger Test kann man es und sollte man es noch nicht sehen, 200 mm und 400 mm Objektive ist noch keine richtige Herausforderung. Aber, aufgrund ihres geringen Gewichts ist sie sehr mobil. Sollte sie wirklich das Zeug haben als Fotomontierung? Das werden wir in den nächsten Tests sehen. Alleine vom Preis her ist die BRESSER EXOS 2 Montierung schon einmal ein guter Kandidat. Sie liegt preislich zwischen Reisemontierung ( meistens ohne Goto-Funktion) und mittelschweren Montierungen, die für den mobilen Einsatz sehr schwer und unhandlich sind.

EXPLORE SCIENTIFIC 2" O-III Nebula Filter
One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects beyond the solar systems enormously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artificial light. The EXPLORE SCIENTIFIC O-III filter uses a characteristic property of the so called emission nebulae. Those objects glow in special colours, the so called emission lines. Those emission lines are linked to chemical elements - in this case oxygen. The EXPLORE SCIENTIFIC O-III nebula filter blocks all other colours (and thereby nearly all of the artificial light) and only the two emission lines of the oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburban skies for example the veil nebula NGC 6992 is almost not visible with a 200mm telescope. By using this filter you can see the nebula and its structures without problems. A must for every visual observer. The EXPLORE SCIENTIFIC nebula filters come with a individual test certificate - your guarantee to receive a premium filter.FEATURESenables the observation of so called emission nebulaeblocks almost the entire artificial lightonly the two emission lines of ionised oxygen passes the filterWHAT'S INCLUDED1x 2" O-III nebula filter

EXPLORE SCIENTIFIC 2" UHC Nebula Filter
One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects beyond the solar system enormously. Depending on the type of the celestial object, it is possible to dramatically increase the contrast by blocking annoying artificial light. The EXPLORE SCIENTIFIC UHC filter "zeros in" on the wavelengths of so-called emission nebulae. Those objects glow in special colours - their emission lines. Those emission lines are linked to chemical elements - in this case hydrogen at 486nm and 656nm, plus oxygen at 496nm and 501nm. The EXPLORE SCIENTIFIC UHC nebula filter blocks all other colour wavelengths (and thereby nearly all of artificial light) and only the emission line of the hydrogen and oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely invisible from, without filters. In suburban skies, for example the Owl-nebula M97, the Veil-nebula NGC 6992 or even the bright Dumbell-nebula M27 are not clearly visible. Using this filter allows you to see nebulae and their structures in much finer detail. A must for every visual observer.

EXPLORE SCIENTIFIC 2" CLS Nebula Filter
Besides air turbulence, the brightening of the night sky is the biggest obstacle to observing faint objects beyond the solar system. Street lamps and other artificial lighting mean that the sky in human settlements is no longer really black. This affects the contrast and thus the perception of deep-sky objects. Depending on the type of celestial object, however, part of disturbing artificial light can be filtered out, making it easier to observe fainter targets.The EXPLORE SCIENTIFIC CITY LIGHT SUPRESSION - or CLS - filter uses the fact that the artificial lighting is not evenly distributed over the entire spectrum. These colours - in the case of the EXPLORE SCIENTIFIC CLS nebula filter, above all the typical colours of mercury and high-pressure lamps, used in street lighting - are suppressed, but the emissions of deep-sky objects are allowed through. With a slightly brightened sky, some relatively bright deep-sky objects are practically invisible with a telescope, for example the large galaxy M101. Using this filter makes observation much easier. A must have for any visual amateur astronomer.  The CLS can also be used as a useful photographic filter - helping to improve the quality of your telescopic deep sky photos.The EXPLORE SCIENTIFIC nebula filters are delivered with an individual test report - so you can be sure of receiving high-quality filters.SPECIFICATIONS:eliminates disturbing light - e.g. from street lightingenables observation of faint deep sky objectsWHAT'S INCLUDED:1x nebula filter

EXPLORE SCIENTIFIC 4K DEEP SKY ASTRO Camera & Guider 8,3 MP II
Enter the world of astrophotography now - with the new EXPLORE SCIENTIFIC 4K DEEP SKY ASTRO Camera including ST4 autoguider function. This is truly new: Equipped with the new high-sensitive IMX585 Exmor CMOS colour sensor, this astronomy camera delivers amazing image results with extremely short exposure times even with basic telescope equipment. In addition, this ultra-modern camera can also be used as an autoguider, e.g. to actively track the main imaging device with an SLR or CCD astro camera. An all-round camera that delivers super-sharp and high-resolution planetary images. The high 4K resolution of 3840x2160 pixels guarantees the best possible image result. Sensor The secret to the high light sensitivity is the new back illuminated Exmor CMOS sensor. It increases the quantum efficiency to up to 77 % at 533 nm, which leads to an extremely high light sensitivity and thus particularly bright and high-contrast photos. In addition, the particularly low noise level of this new CMOS sensor generation ensures exceptionally high brilliance and no active cooling is required. Nevertheless, this astro camera has an elaborate internal structure made of aluminium for ideal heat radiation and a fan that can be switched on via software. When used with suitable telescopes, the high native pixel resolution of 3840x2160 enables very nice overview images of the moon, but also detailed planetary images. Solar Imaging This camera is also recommended for solar astro-photography. Especially the Lunt LS40 THa solar telescopes (item No. 0551145/0551146/0551147), with their short focal length, allow in combination with this planetary camera with its large sensor great overview images of the sun. Important Note: When observing and taking photos of the sun, always use a suitable protective solar filter or a special solar telescope. Otherwise there is a risk of immediate blindness and damage to the camera. Software The included Explore Capture professional software offers not only the necessary basic functions for image and video capture, but also many helpful special functions for image post-processing and for setting up the guider. Functions such as live image display, exposure settings, white balance, dark image capture, stacking, timelapse recording and much more can be configured individually. Especially the very sophisticated software makes it really easy for you to get started in astrophotography. With the automatic settings you can produce absolutely presentable results without a lot of prior knowledge. And when you are ready, simply switch off the automatic settings and gradually venture into the individual professional settings. Automatic tracking control Connect the camera directly to the ST4 port of your telescope mount and you have a fully automatic tracking control. Thus, long exposures of several minutes are possible without the stars producing unwanted star traces due to the always existing periodic error of the telescope mount gears. A corresponding ST-4 connection cable is even included in the camera's scope of delivery. Because of the high light sensitivity of the camera, you will always find a suitable guide star even with very short exposure times. Simple automatic tracking at its best. Connection For the connection to telescopes, guiding scopes or off-axis guiders the camera has a 1.25'' socket with 1.25'' filter thread (M28.5x0.6) and a large T2 connection thread (M42x0.75) directly on the housing. IMPORTANT NOTES: This is not a stand-alone guider camera. You always need a Windows 10 or 11 computer to take pictures and for autoguiding. The autoguider software is not included. You can use PHD2 Guiding, GuideDog, Metaguide, Guidemaster (freeware) or AstroArt, MaxIm DL (paid).

EXPLORE SCIENTIFIC 68° Ar Eyepiece 16mm (1,25")
With the introduction of the 68° Series we are pleased to make two important improvements in eyepiece manufacture, the first being 15 layer Enhanced Multi-layer Deposition (EMD™) coatings on all glass-to-air surfaces to gain maximum contrast, and waterproofing the eyepiece with the use of Argon gas purging instead of standard Nitrogen gas. Although Nitrogen is a fine choice that will last for many years, Argon is a larger molecule that maintains its protective properties over a wider range of temperatures, and is even more resistant to diffusion thereby further extending the protective waterproof environment of the eyepiece body. Through computer-optimized design, a careful selection of optical glasses, and enhanced multi-layer deposition coatings, the Explore Scientific 68° Series™ eyepieces produce long eye-relief and ensure high image-correction, a flat field, and high contrast across the entire image field. An excellent choice for those who make extended visual studies of detail with subtle variations of brightness, and for those who must wear glasses while observing. All 68° Series eyepieces are fully EMD (Enhanced Multi-Layer Deposition) coated and edge-blackened to produce superior contrast.

EXPLORE SCIENTIFIC 82° Ar Eyepiece 8.8mm (1.25")
Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the "averted vision" technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

EXPLORE SCIENTIFIC Ultra Light 20'' Dobson 500mm f/3.6 GENERATION II
Ultra Light Dobsonian 500mm GENERATION II - telescope mechanics handcrafted in HUNGARY and GERMANY No telescope type has influenced amateur astronomy as radically as the dobsonian telescope. Before the introduction of this telescope type by John Dobson the vast majority of amateur telescopes were small inadequate refractors on shaky mounts - just good enough to show the polar regions on mars or the rings of Saturn. Bigger telescopes, like the Schmidt-Cassegrain telescopes, were restricted to the relatively small group of amateurs that could afford them.The brilliant combination of simple - but effective - mechanics and the largest aperture available led to a worldwide triumph of this concept. No other telescope type offers you so much light for your money as a good dobson. We have taken the motto held together by gravity and driven by yoghurt power and offer a modern version of the classic - designed by amateur astronomers for amateur astronomers. Despite its large aperture the telescope can be transported easily even in small cars and is assembled within minutes without tools. The construction was optimized for maximum rigidity with a minimum of mass. The combination of big altitude wheels and a optimized aluminium-sandwich construction allows for small movements even at high magnifications. The focus position is already positioned to accept our coma-corrector (part No. 0510330) . The ideal workhorse for the deep-sky enthusiast. A telescope with 500mm aperture gathers more than 5100-times more light than the naked eye. Details on planetary surfaces stand out even to unexperienced observers, and countless deep-sky objects show details and some color. Bright globular clusters are resolved down to the core and the view of the lunar terminator will provide a unforgettable experience. The fast 20’’ f3.6 main mirror as well as the large 120mm secondary mirror are made of high quality quartz material, so the cooling time is reduced to a minimum and the Dobson is quickly ready for use. Every main mirror is delivered with an individual optical test certificate, which guarantees the highest capacity. A laser engraved center mark of the main mirror allows easy adjustment. The optical surface has a high-quality aluminum silvering with 94% reflectivity and an extremely resistant quartz protection layer. The mirror overcomes frequently occurring dew fogging and cleanups without any damages and guarantees a long service life. A complete redesign of this Dobson was necessary to ensure the significantly increased requirements to stiffness and load bearing capacity of the optical components. All connections of the tube structure were made in the TIG welding process and no rivets and screws were used. This has made it possible for us to produce this 20’’ light weight Dobson so unbelievably stiff in spite of the low weight - a noticeably good quality which is searching for its match. The production of almost all mechanical components is carried out by our partners in Hungary and the final assembly of the optics and subsequent quality control takes place in Rhede, Germany. The equipment details of the smaller Dobson models, which have been popular for years, have been taken over and even extended considerably. First of all, of course, the very good decomposability and transportability should be mentioned. Set-up and dismantling can be carried out without tools. The main and secondary mirrors are adjustable during the observation and only two adjusting screws have to be moved. Thanks to the use of precision ball-heads in the main mirror cell and a precision hinge for secondary mirror suppport, the adjustment is absolutely easy and guarantees excellent stability. All connecting parts of the tube trusses now consist of CNC machined aluminum and are attached by stainless steel dowel screws. The secondary mirror can now also be adjusted by the adjusting screws in the direction of the optical axis. The tried and tested 2.5’’ HEXAFOC focuser with 1:10 fine adjustment has been used for years - this allows vignetting-free observation despite the fast aperture ratio. A second 40° displaced installed mounting plate with a viewfinder shoe allows the rotation of the tube top in combination with a favorable position of the viewfinder tube or the mounting of an additional TELRAD viewfinder. The 6 supporting feet underneath the rockerbox offer a perfect stability and guarantee a smooth tracking in azimuth. Four smaller fans are installed in the side of the mirror box as well as a large fan is installed under the main mirror. This allows an even quicker adaptation to the ambient temperature and reduces the tube seeing (boundary layer removal). The lateral altitude wheels can now be stowed comfortably in the foam layers of the mirror box. Last but not least another gimmick: The optical tube and the mirror cell are designed to use also on heavy equatorial mounts.
