BRESSER Messier MC-127/1900 EXOS-1/EQ4 Telescope

Testbericht zu BRESSER Messier MC-127/1900

von Michael M.

Den Bresser Messier Maksutov-Cassegrain mit 127 mm Öffnung wollte ich als Mondbeobachter schon lange einmal kennenlernen. Durch eine Korrespondenz in anderer Sache mit Wolfgang Quere ergab sich das Angebot von Bresser, das Gerät einmal leihweise für einen Test-Bericht zu bekommen. Dieses Angebot nahm ich gerne an und möchte im nachfolgenden meine Eindrücke beschreiben.



Das Gerät kam sehr gut verpackt und wohlbehalten bei mir an. Das obige Bild zeigt das Gerät im fertig montierten Zustand mit dem beiliegenden Lieferumfang.

Zum Gerät selber kann ich sagen, dass es sauber verarbeitet ist und sowohl mechanisch wie auch vom Finish einen guten Eindruck macht. Am Gerät ist eine typische GP-Level Prismenschiene verbaut, die auf der Klemmseite mit einer Edelstahlschiene vor Klemmspuren geschützt wird. Ferner hat der MC vorn eine schöne Kunststoffabdeckung um die Meniskuslinse zu schützen. Diese hat, so wie man es auch von Foto-Objektivdeckeln kennt 2 Rastnasen – recht praktisch.

Der Tubus ist ein solider Alu-Tubus und macht einen stabilen Eindruck. Die Lackierung an meinem Gerät ist sehr sauber und gut ausgeführt. Den rückwärtigen Abschluss des Gerätes bildet eine Fassung aus stabilem Kunststoff. Dies mag vielleicht zunächst etwas ernüchternd wirken, dennoch muss ich sagen, dass während des Gebrauchs keine Einschränkungen zu bemerken waren. Diese Abdeckung ist sehr stabil ausgeführt.

Der Fokussiermechanismus erinnert sehr stark an das altehrwürdige Meade ETX 125. So wie auch die technischen Daten dieses Maksutov Cassegrain fast wie eine Re-Inkarnation des ETX 125 anmuten.

Der Fokussierknopf wirkt bei erster Betrachtung etwas zierlich, hat sich aber im Beobachtungsbetrieb bewährt. Die Fokuslage lässt sich sehr feinfühlig und butterweich verstellen. Erfreulich bei diesem Exemplar auch : das sogenannte Shifting fällt sehr gering aus ! Da habe ich schon ganz andere Erfahrungen machen müssen !

Wenn es etwas zu kritisieren gibt, dann sind es für mich die schwer zugänglichen Justierschrauben zur Kollimation des Hauptspiegels. Sie sind sind auf der hinteren Gehäuseabdeckung hinter drei Gummiabdeckungen versteckt. Leider ist die Öffnung dahinter recht schmal und klein, zudem liegen die Justierschrauben relativ tief und haben auch noch 2 unterschiedliche Inbusgrößen. So wird die Justierarbeit schnell zur mühseligen Fummelei. Vielleicht könnte man bei einer nächsten Gerätegeneration die Zugänglichkeit hier etwas verbessern



Ansonsten gibt es bezüglich der mechanischen Ausführung des Gerätes eigentlich nichts zu mäkeln.Die Optik kam absolut sauber und fusselfrei an; die Tubus-Innenschwärzung könnte evtl. noch etwas besser sein, erfüllt aber auch so ihren Zweck, wie sich bei den Beobachtungen zeigte. Ach ja : was das Zubehör angeht – den mitgelieferten Leuchtpunktsucher sollte man am besten gleich durch einen vernünftigen Sucher ersetzen. Aus meiner Sicht ist das Ding nahezu nutzlos.

Einen Punkt wollte ich noch überprüfen : im Internet gab es zuweilen Gerüchte, das die bekannten 5“ Maks eines Mitbewerbers in Wirklichkeit nur mit c. 119-120 mm Öffnung arbeiten. So überprüfte ich den MC-127 auf seine „wahre“ Öffnung. Auch hier gibt es bei Bresser keine Mogelpackung – das Gerät arbeitet mit den vollen angegebenen 127 mm Öffnung.

Leider ergaben sich im Leihzeitraum für mich nicht sehr viele Beobachtungsmöglichkeiten, dennoch konnte ich mir einen recht guten Eindruck hauptsächlich bei der Mondbeobachtung, an Doppelsternen und zum Schluss auch noch kurz an Mars machen.



Aufgebaut ist das Gerät hier auf meiner Terrasse, auf einer relativ hohen Säule, die ich eigentlich für meine Refraktoren nutze. Als Montierung dient meine altehrwürdige Meade LXD 650. Das ist natürlich schon over-kill für den kleinen Mak. Eine einfache EQ-3 oder auch ältere Vixen New Polaris Montierung würden für den Bresser MC 127 vollkommen ausreichen.

Mond:

An mehreren Abenden bzw. ganz frühen Morgenstunden ergaben sich Möglichkeiten zur Mondbeobachtung. Da ich sonst vorwiegend mit achromatischen Refraktoren beobachte, war zunächst einmal die völlige Farbreinheit des Maksutov für mich ein schöner Effekt. Genutzt habe ich vorwiegend meine Baader Classic Orthos, sowie ein Baader 32 mm Super Plössl. Am Mond waren Vergrößerungen bis ca. 240x mit einem 7mm SPL ohne Schwierigkeiten machbar, ohne dass das Bild „matschig“ wurde - ein sehr schönes Ergebnis ! An eine Grenze stieß ich dann erst mit dem 6 mm Classic Ortho. Bei dann immerhin schon 316x wurde es sehr schwer bis zeitweise unmöglich einen eindeutigen Fokuspunkt zu finden. Das mag z.T. Am vorherrschenden Seeing gelegen haben, zeigt aber vielleicht auch die Grenzen dieser Optik auf.

Der Fairnes halber muss ich aber auch sagen, dass ich bei 4“ und 5“ Geräten mit 200facher Vergrößerung am Mond eigentlich alles sehe, was diese Öffnungsklasse hergibt. So gesehen ist 316x schon eindeutig im Bereich der Übervergrößerung anzusiedeln.

Nachstehend ein paar Aufnahmen, welche mit recht einfachem Equipment gewonnen wurden : eine einfache Kompaktdigitalkamera wurde per Digi-Halterung hinter das Okular gebracht und über die Videofunktion AVI Videos gefilmt, die dann mit Autostakkert 2.0 verarbeitet wurden.

Zunächst aber eine Fokalaufnahme mit einer Samsung NX20 DSLM...

Mars :

Fast am Ende der Leihzeit ergab sich die Möglichkeit zumindest noch einen kurzen Blick auf Mars zu erhaschen. Leider stand der rote Planet die meiste Zeit einfach zu tief und wurde an meinem Beobachtungsstandort z.T. auch durch Bäume und Häuser verdeckt. Auch blieb mir jeweils nur ein kurzes Zeitfenster, bevor der Planet wieder hinter Bäumen oder Häusern verschwand.Dennoch konnten die Polkappe, einige Strukturen ( Syrte ? ) und blickweise sogar Olympus Mons noch beobachtet werden. Alles in allem ein schöner Anblick trotz des tiefen Planetenstandes und der widrigen Bedingungen.

Doppelsterne:

Pi Aql : konnte mit 1“4 Abstand im 18er Classic Ortho bei 105x schön getrennt werden.

e Lyrae: locker getrennt schon im 32er Super Plössl

sowie weitere Doppelsterne im Orion, der ja reich an Doppelsternen ist. So konnte ich in den frühen Morgenstunden des 30.09. trotz Mondhelligkeit einige Kandidaten im Orion gut beobachten.

eta Ori : im 18er leicht getrennt, wobei auch die nahezu gleiche Helligkeit hilft

zeta Ori : trotz 2“4 Abstand gar nicht mal soo einfach, da doch ein ziemlicher Helligkeitsunterschied

32 Ori : mit 1,2“ schon etwas schwieriger, zumal bei seeing 6/10, aber bei 190x gut aufgelöst

Was insgesamt beim Bresser Maksutov-Cassegrain positiv auffällt, ist die offenbar gute Optik des Gerätes. Zwar steht mir nun keine optische Bank zur Verfügung, aber es ist schon immer ein gutes Zeichen, wenn sich beim Fokussieren eine eindeutige Fokus-Lage einstellt. Ich habe im Laufe der letzten 20 Jahre schon durch viele Optiken gucken dürfen – sei es nun Refraktoren, SC's, Maks oder Newtons. Auch einige, weniger gute Geräte waren dabei. Bei solchen, minderwertigen Optiken „eiert“ man geradezu immer eine Weile um den richtigen Fokuspunkt herum. Man dreht am Fokussierer hin und her und findet doch nie den Punkt, an dem man meint, die richtige Schärfe gefunden zu haben.

Nicht so bei diesem Bresser MC 127 – beim Fokussieren stellte sich stets schnapp-artig ein klar definierter Schärfepunkt ein. Man weiß genau: hier ist es scharf, schärfer geht’s nicht.

Als Fazit kann ich für mich festhalten : der Bresser MC 127 ist ein sich stimmiges Gerät. Er hat eine sehr gute, scharfe Optik und ist mit seiner Brennweite und Öffnung ein ideales kleines Gerät für Mond- und Planetenbeobachter. Aber auch Doppelsterne machen Spaß. Zudem ist der MC-127 ein sehr kompaktes und leichtes Gerät. Er lässt sich kostengünstig montieren und Dank seiner Größe und seines Gewichts auch gut auf Reisen mitnehmen.

Bedenkt man den Preis von rund 350€ kann man hier sogar von einem echten Preis-Leistungs-Wunder sprechen ! Man kann leicht das mehrfache an Kosten ausgeben, ohne wirklich mehr zu sehen.

Ein absolut empfehlenswerter Maksutov-Cassegrain !

EXPLORE SCIENTIFIC 1.25" 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 enourmously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artifical light. The EXPLORE SCIENTIFIC O-III filter uses a characteristic property of the so called emmission nebulae. Those objekcts glow in special colors, the so called emmission lines. Those emmission lines are linked to chemical elements - in this case oxygen. The EXPLORE SCIENTIFIC O-III nebula filter blocks all other colors (and thereby nearly all of the artificial light) and only the two emmission lines of the oxygen can pass the filter. The result is astonoishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburbian 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 emmission nebulaeblocks almost the entire artificial lightonly the two emmission lines of the oxygen passes the filterSCOPE OF DELIVERY1x 1,25" O-III nebula filter

EXPLORE SCIENTIFIC 1.25" 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 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 UHC filter uses a characteristic property of the 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 colours (and thereby nearly all of the 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 empty without filters. In suburban skies for example the Owl-nebula M97, the Veil-nebula NGC6992 or even the bright Dumbell-nebula M27 are not clearly visible. By using this filter you can see the nebulae and their structures without problems. A must for every visual observer.

EXPLORE SCIENTIFIC 1.25" 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 EXPLORE SCIENTIFIC 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 CLS filter

EXPLORE SCIENTIFIC Filter Set 1 Moon & Planets from 50mm (2'')
Filter Set 1 is recommended for Moon & Planets from 50mm (2'') Aperture Set 1 includes the following filters: Explore Scientific Filter 1.25" Light Yellow No.8 - 0310268 Watching the Moon surface through the filter, the contrasts will enormously increase. Same with planet Mars. On the huge planet Jupiter, when using the filter, you can even see the contrasts between the cloud-bands and a lot more details. Starting with a telescope diameter of 8“ and a clear sight, you even get to see various details of Saturn. Explore Scientific Filter 1.25" Orange No.21 - 0310273 This one really supports the detection of the dark areas on the planet Mars. The details of the clouds of Saturn and Jupiter are also so much more visible through the Filter. Explore Scientific Filter 1.25" Blue No.80A - 0310264 The color of light blue really supports watching the high clouds on Mars. The contrast increases. The dark red structures will be shown even darker, so this is the perfect filter for watching the big red Flecks on the gas planet Jupiter. The rings of Saturn will be accentuated, the structures of the Venus Atmosphere will be even finer. EXPLORE SCIENTIFIC 1.25" Filter Grey ND0.9 - 0310245 The neutral density filter transmits light uniformly across the entire visual spectrum. It serves as an excellent filter to reduce glare and irradiation when observing the Moon with any telescope 4"(10.2cm) and larger. The ND96 filter may also be employed in the splitting of close double stars where one of the binary pair significantly exceeds the other in brightness. What ist a color Filter for and do we really need it? Color Filters darken the light slightly, that reaches the eye or the sensor of the camera. This eliminates for instance stronger transitions. The result is that your picture turns out with more contrast which automatically shows more details.

You can also use wider-bodied astronomical cameras (non-c-mount), which have T2 threads built into their bodies, as standard with this camera adapter. This adapter can be separated into two different lengths of 30mm and 80mm (which both truncate in a T2/M42 thread). The use of these different lengths of extension tube allows the user to vary the projection of image on to a camera chip and get the best framing for the size of object being imaged. Please note: an extra camera specific T2-adapter ring (Canon, Nikon, Sony, etc.) is necessary to connect a DSLR.  Many of these are available from us and you are welcome to contact us for advice if unsure which of these to pick.WHAT'S INCLUDED Camera-Adapter with M35x1,0mm to M42x0.75mm (T2) thread

EXPLORE SCIENTIFIC 52° LER Eyepiece 10mm Ar
Mid-range high power eyepieces like the 10 mm are instrumental when transitioning through magnifications to observe an object until it is best seen. There are several aspects that have to come together when observing at high powers: good-to-perfect atmospheric seeing conditions; telescope optics that are collimated; a telescope that is acclimated to the ambient temperature; brightness and size of the object being observed are just a few aspects to consider. The observing challenges are high, but the rewards of observing at high power with razor sharp views are unforgettable. Comfort, Quality, Value. The Explore Scientific 52° LER Series Most short focal length eyepieces are excellent flat-field multi-element oculars that can transform your visual astronomy experience. With an apparent field of view of 52 degrees, these eyepieces offer incredible value in a very nice eyepiece. Expect exceptional quality and value versus a comparably priced Plössl. These eyepieces are the choice for observers wearing glasses - with excellent performance and durability. The rubber inlet and the foldable eyecups make handling and using in the field easy. The patented EMD-coating produces high contrast images and prevents reflexes and ghosting. The argon purging effectively prevents internal fogging, and you don't have to deal with dirt, fungus or cleansing fluids getting between the lenses. The eyepieces are sealed - this makes sure you will be able to enjoy these eyepieces for many years to come.SPECIFICATIONSLarge eye distance, large field and great image sharpness Excellent viewing position for people with glassesExcellent field sharpness even with fast optics52° apparent field of viewArgon-purging prevents internal fogging, the sealing facilitates cleaningPatented EMD-coating to maximize contrastBlackened lens edges to avoid reflexesAll eyepieces of this series are parfocalStainless steel barrel with conical security cutoffDust covers and protective bag includedSCOPE OF DELIVERY52° EyepieceDust coversProtective bag

BRESSER Barlow Lens 2x 31.8mm/1.25"
With the usage of barlow lenses, you can extend the equivalent focal length of telescopes and hence increase the magnification of your observed targets. Subsequently, you can use lower power eyepieces in Barlows to act as much more powerful eyepieces, but retain the larger ocular size and more comfortable viewing that comes with lower power eyepiece designs.Due to their two lens design, these Barlow lenses provide a brilliant image quality for the whole visual field and are suitable for observations and photography.  The black coloured Barlow element cell in this BRESSER Barlow Lens 2x 31.8mm/1.25," can be unscrewed and has the same thread as 1.25" filters, allowing it to be mounted in 1.25" eyepieces, t-adapters and other accessories, giving you flexibility of use and the ability to vary magnification in different accessories.  For instance, the black Barlow cell screwed into the average length nosepiece of a standard push fit t-adapter will give around 1.6x magnification on an attached DSLR.  This can be very useful when trying to get to photographic focus with some Newtonians and Solar Telescopes, which lack the necessary amount of in focus travel to get a camera to a prime focus position.FEATURESsuitable for observations and photographydoubling of the focal lengthtwo lens designfully multi-coatedWHAT'S INCLUDEDBarlow lens (1pc)

EXPLORE SCIENTIFIC 82° Ar Eyepiece 4,7mm (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.

BRESSER Messier MC-100/1400 EQ3 Maksutov-Cassegrain Telescope with Smartphone Adapter & Solar Filter
Take your first steps into the wonderful world of astronomy – with this complete set consisting of an astronomical Maksutov-Cassegrain telescope with 100 mm aperture and 1400 mm focal length, equatorial EQ-3 mount, tripod and extensive accessories. The special feature of this beginner’s telescope: Due to the high contrast, you can start your journey to the stars wherever you like – even in the middle of a brightly lit city. And yet the extremely compact telescope takes up very little space on balconies, terraces and the like. The system is easy to handle and therefore perfect for beginners. The optics show especially the Moon and planets at their best. Ideal for all travel-loving amateur astronomers: due to its compact design, the telescope is also perfectly suitable as a travel telescope. Compact high-quality optics for beginners – the telescope Powerful optics with a long focal length in a very compact design for easy transport – that is what Maksutov-Cassegrain telescopes offer. The design principle: The optics combine mirrors and lenses with very good imaging properties. With the 100 mm aperture, the BRESSER Messier MC-100/1400 already collects a lot of light and offers a good resolution. Due to the extremely large focal ratio of 1 to 14 (F/14), which results from the 100 mm aperture and the 1400 mm focal length, you enjoy a very sharp image with excellent contrast. This means that the telescope is an absolute specialist when it comes to exploring the Moon, Sun and planets. But you can also look forward to observing many deep-sky objects through your telescope for beginners. Admire open star clusters, globular clusters and so-called planetary nebulae such as the impressive Dumbbell Nebula M27. Really sharp images with up to 200x magnification – no problem thanks to the resolution of the 100 mm aperture! From a purely technical point of view, even more is possible in terms of magnification. However, increasing magnification often results in a loss of image sharpness. Moreover, the telescope is not the only factor when it comes to the question of how high you can magnify. The air turbulence in the atmosphere (seeing conditions) also plays an important role. Good foundation for your space exploration – mount and tripod While you enjoy the view of the sky, your Maksutov-Cassegrain telescope is perfectly mounted on the height-adjustable aluminium tripod with equatorial EQ-3 mount. The equatorial design has a decisive advantage: Unlike azimuthal models, you have to compensate for the movement of the celestial bodies on just one axis. To do this, you align this particular axis of the equatorial mount parallel to the Earth's axis by pointing it approximately at the polar star – also known as "alignment". Thanks to the two flexible shafts with fine adjustment, tracking and adjusting the telescope is extremely comfortable and precise. The storage plate between the tripod legs keeps your astronomy accessories ready for any exciting discovery.Keep track of things automatically: For this telescope’s equatorial EQ-3 mount, the tracking motor with item number 4951400 is available as an optional accessory. This eliminates the need to manually track a celestial object set in the telescope. When this motor is installed at the mount, it automatically tracks the celestial object, keeping it in the field of view of the eyepiece. This makes observing the night sky even more comfortable! Complete equipment for your start in astronomy – the accessories Unpack and get started straight away – with the extensive accessories, you can immediately set off on your own exploration trip through our solar system. The LED viewfinder allows you to find celestial objects easily and align the beginner's telescope precisely. For this purpose, the viewfinder is mounted parallel to the actual telescope. And this is how it works: Inside, a red dot is projected onto a small ground-glass screen. When you then look through the LED viewfinder, this dot appears to be floating in front of the sky – exactly where your telescope is pointing. The eyepiece included in the astronomy set is impressive as well. The 26 mm Plössl eyepiece offers a 54x magnification and very good imaging properties. Simple upgrade: Because the tube diameter of 31.7 mm (1.25 inch) corresponds to an international standard for all manufacturers, you can easily extend your astronomy starter set with additional eyepieces. This way you can admire your favourite sights in other magnifications as well. Especially when the telescope is pointed vertically into the sky, the 90-degree star diagonal mirror proves to be very helpful. It allows you to look into the telescope comfortably from the side, even at unfavourable viewing angles. Fascination Sun – with the Maksutov-Cassegrain beginner's telescope, you can take a close and safe look at our own star. Simply attach the solar filter to the aperture. The sight of sunspots and granulation on the Sun is guaranteed to amaze you! ATTENTION: Never point the telescope at the Sun without the solar filter! Capturing breathtaking astronomy moments is easier than ever. Simply place your mobile phone with the smartphone adapter on the eyepiece, take pictures and share the most beautiful snapshots of the Sun, Moon etc. immediately. FEATURES Maksutov-Cassegrain telescope for beginners with 100 mm aperture and 1400 mm focal length Very good for observing Sun, Moon, planets and star clusters Very compact dimensions, therefore well suited for the balcony or as a travel telescope Height-adjustable tripod with equatorial EQ3 mount Precise adjustment through flexible shafts and fine adjustment in both axes Easy to use, good for beginners Focal ratio F/14, thus very sharp image and excellent contrast 26 mm eyepiece of the "Plössl" type with 31.7 mm (1.25 inch) sleeve for 54x magnification Safe solar observation with the included solar filter Entry into astrophotography with smartphone camera adapter SCOPE OF DELIVERY Telescope Aluminium tripod Equatorial EQ3 mount Eyepiece: 26 mm Plössl (1.25 inch socket) Star diagonal mirror LED illuminated dot finder Solar filter Smartphone camera adapter Accessory tray Astronomy software download Instruction manual
