Erfahrungsbericht zum Bresser NT-150S/750

von Marco Hodde

Am 20.2.2018 bot sich bei klarem Himmel die Möglichkeit, den NT-150S/750 einmal optisch und fotografisch genauer unter die Lupe zu nehmen.

Bresser NT-150S/750

Bresser NT-150S/750

Zum Teleskop: Mit einer Öffnung von 150 mm und einer Brennweite von 750 mm ergibt sich ein Öffnungsverhältnis von f/5. Persönlich finde ich dieses Öffnungsverhältnis sehr gut für einen Allrounder. Würde ich bei Deep Sky Beobachtungen eher zu schnelleren Öffnungsverhältnissen neigen (f/4 oder gar f/3), so verzeihen diese einem bei der Justage keinerlei Toleranz, welches sich in der Abbildung bemerkbar macht. Bei Planetenbeobachtungen kommen eher größere Öffnungsverhältnisse in Frage ( f/5 bis zb f/13).

Fazit: Mit einer Öffnung von 150mm, einem Gewicht von gerade mal 5,5kg und einem Öffnungsverhältnis von f/5, finde ich das Gerät als Multitalent überall einsetzbar.

Hier geht es zum Produkt!

Dank des im Lieferumfang enthaltenden Zubehör, habe ich die Möglichkeit sowohl mit 1,25“ als auch mit 2“ Okularen zu beobachten. Nicht nur das, auch fotografisch kann ich ohne Probleme eine handelsübliche Kamera auf den integrierten Kamerahalter (befestigt am Handgriff) aufsatteln.

Optischer Eindruck: Nachdem ich das Teleskop auf meine Montierung gesattelt habe, habe ich den offenen Tubus ca 1 Stunde auskühlen lassen, damit der Hauptspiegel die Umgebungstemperatur erreicht. Dies ist wichtig , damit sich das Teleskop an die vorherrschenden Temperaturen anpassen kann. Nun konnte das Beobachten beginnen. Mit dem im Lieferumfang enthaltenen 26mm Okular erreicht man eine 29fache Vergrösserung (750mm Brennweite/ 26mm Okular = 29). Der erste Blick, wie sollte es anders sein, richtete sich in der Winterzeit auf den Orionnebel. Diesen bekommt man schön in seiner ganzen Größe ins Gesichtfeld. Man kann auch die Trapezsterne erkennen. Nun ein Schwenk zum Sternhaufen NGC 2158 und M 35. Die Sternabbildungen sind sehr schön und es macht Spaß die Fülle der Sterne auf sich wirken zu lassen.

Fazit: Die Meinung, man müsse so hoch vergrössern wie nur irgend möglich, ist es ein riesen Irrglaube!!!! Es macht wesentlich mehr Spaß bei kleinerer Vergrößerung ein schön kontrastreiches Bild zu erleben, als sich bei höchstmöglicher Vergrößerung mit kleinem Gesichtsfeld und unscharfer Abbildung zu plagen. Mein Eindruck war auf jeden Fall sehr positiv

Fotografischer Eindruck: Zum fotografischen Teil meines Erfahrungsberichtes. Da ich optisch beim Sternhaufen NGC 2158 und M 35 angelangt war, so nahm ich diese auch als Ziel, fotografisch festzuhalten. Zu den Daten: Die Fotos entstanden mit meiner Canon EOS 760d und die Belichtungszeiten waren bei ISO 400 je 2,5 Minuten. Wer seine DSLR direkt an das Teleskop adaptieren möchte, der benötigt lediglich einen Adapterring von T2 auf das passende Kamerabajonett. Der beim Teleskop enthaltene Okularauszug beeinhaltet nicht nur eine 2“ Steckhülse sondern auch ein T2 Aussengewinde an der 1,25“ Steckhülse.

Nun kommt ein wichtiger Aspekt der jedem klar sein muss, der das Teleskop fotografisch nutzen möchte. Grundsätzlich ALLE Newton Spiegelteleskope verursachen einen Koma genannten Fehler. Dies bedeutet, dass Sterne am Rande des Bildfeldes länglich verzogen werden. Je kürzer das Öffnungsverhältnis ist, desto stärker tritt dieser Effekt auf. Aus diesem Grund empfehle ich einen Komakorrektor. Ich habe bei meinen Aufnahmen einen Komakorrektor von Explore Scientific benutzt: EXPLORE SCIENTIFIC HR Coma Corrector

Zum Vergleich habe ich eine Einzelbelichtung mit und eine ohne Korrektor in mein fotografisches Ergebnis eingefügt

Fazit: Ein sehr lichtstarkes Teleskop, welches mit seiner Brennweite ideal ist um Nebelgebiete wie zum Beispiel den Orionnebel fotografisch festzuhalten. Bedingt durch den auftretenden Komaeffekt ist ein Komakorrektor zwingend erforderlich. Beim Einsatz des Explore Scientific Korrektors wird zusätzlich noch die Verlängerungshülse benötigt, welche beim Teleskop dabei ist, um in den Fokus zu kommen. Sollten Sie ohne Korrektor fotografieren, so schrauben Sie die Verlängerungshülse vom Okularauszug ab um in den richtigen Fokus zu kommen

Dann, zwei Tage später am 22.2.2018 zeigte sich wieder ein sternklarer Himmel. Also baute ich das Teleskop wieder auf. Diesmal allerdings wollte ich einen Nebel fotografieren. Ich entschied mich für M 97 Eulen-Nebel und die Galaxie M 108. Beide sollten sehr gut ins Bild passen. Der Unterschied zum Sternhaufen lag allerdings fotografisch im Detail. Da ich im tiefsten lichtverschmutzten Ruhrgebiet wohne, benötigte ich einen Nebelfilter. Ich probierte den 2“ UHC Nebelfilter von Explore Scientific aus, welchen ich direkt an den Komakorrektor schraubte. Das unten stehende Ergebnis zeigt, wie viel Details der Filter herausholt und wie enorm viel Störlicht er blockt.

Am Ende stellte ich fest, dass mir das Teleskop sehr gut gefallen hat und nicht nur optisch mit seiner relativ geringen Brennweite ein tolles, lichtstarkes Bild lieferte. Mit ein wenig Zubehör lässt sich zudem auch fotografisch einiges aus dem Gerät herausholen !!!

Warning notes
  • Check the solar filter before every solar observation and ensure that it is not damaged. Hold it against a strong light source to detect any possible cracks and/or holes. Do not use the telescope for solar observation, even if the solar filter is only slightly damaged. In this case, contact the manufacturer for the appropriate replacement parts.
  • Always use the included solar filter when observing the sun. Make sure it is correctly attached to the telescope according to the instructions. The use of the solar filter is only intended in connection with this telescope.
  • Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
  • Check the secure fit of the solar filter before each solar observation. An accidental detachment from the objective opening can lead to immediate and permanent eye damage and blindness.
  • If the solar filter cannot be securely attached to the tube, improve the fit by placing several self-adhesive felt strips or similar between the solar filter and the objective opening. Never use the solar filter if it cannot be properly mounted on the telescope. In such a case, always contact our customer service first.
  • Be extremely cautious when observing the sun. A brief look through the unprotected optics will immediately cause severe eye damage, potentially leading to complete blindness.
  • Children should not look at the sun through the telescope, even with the filter properly installed. Never leave children unsupervised.
  • Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
  • Do not observe the sun after eye surgeries or other eye conditions without prior medical consultation.
  • Wrinkles/creases in the film are normal and do not indicate a product defect.
  • Do not expose the device to high temperatures.
  • BATTERY WARNING AND SAFETY Safe handling and use of batteries and accumulators Read and follow these instructions before using the battery or accumulator. To the extent permitted by law, failure to comply with these warnings and instructions may result in any damage caused to your product not being covered by the warranty. In this document, the term "batteries" also includes accumulators. Follow these instructions to ensure optimal safety and performance: DO NOT use counterfeit batteries in products. Only use supplied batteries. Use the battery SOLELY for its intended purpose. Keep batteries out of the reach of children and pets. DO NOT use batteries that appear to be damaged, swollen, or modified. Do not use batteries that are leaking, emitting a smell, swollen, melted, or showing dents, rust, cracks, or scratches. The battery should NOT be disassembled, crushed, punctured, shredded, or otherwise tampered with. The battery should NOT be exposed to liquids. Liquid may penetrate the battery's circuits, causing corrosion and compromising its safety. A wet or damp battery should NOT be dried with a device or heat source (e.g., hairdryer or microwave). The device or battery should NOT be placed near a heat source or direct sunlight. High temperatures can cause the battery to swell, leak, or malfunction. Examples include placing the device near a radiator, stove, kitchen appliance, iron, fireplace, or inside a vehicle or next to a window in direct sunlight. The battery should NOT come into contact with metal objects. If metal objects such as jewelry come into prolonged contact with the battery terminals, the battery may become very hot or catch fire.

EXPLORE SCIENTIFIC 2" O-III Nebula Filter
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

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
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 Filter Set 1 Moon & Planets from 50mm (2'')
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.

EXPLORE SCIENTIFIC HR Coma Corrector
EXPLORE SCIENTIFIC HR Coma Corrector
After three years of testing and refining we are extremely proud to present the new Explore Scientific High Resolution (HR) Coma Corrector. This corrector is a class of it´s own - it is fully functional for visual use and expands the focal length by only 6%! The Explore Scientific Coma Correktor is delivered as a complete set together with a rotating helical focuser with laser-etched scale, so you get a full package: corrector, adaptor to T2 (M42x0.75mm), adaptor to M48 (M48x0.75) and the helical focuser for visual fun. This coma corrector really is "high resolution" - it deliveres a visual polystrehl performance of 0,98 at f/4 and 0,96 at f/3! So it can stay in the telescope - and you will not only enjoy a tack-sharp Jupiter, but aslo sharp and defined moons in the future! What this means in terms of performance is shown in the three pictures with the graphs - the sharpness increase in those comparisons with and without corrector are stunning (examples are 400mm f/4, f/3,5 and f/3). Please notice: These graphs are for FLAT FIELD! You will get this performance without refocussing! Diameter of the field is 30mm - it doesn´t make sense to increase this with 2" and fast optical systems. Length of the 2" corrector barrel is approx. 85mm and it can be used with almost all 2" focusers on the market. To use the HR Coma Corrector visually, you need to have at least 32mm spare inward travel at your focuser, while the focus is on the same plane as the focusers end. Photographically there is no problem - the HR Coma Corrector shifts the focus outward by about 35mm, so that you will have no problem in achieving focus, when you are able to focus your camera without the HR Coma Corrector. FEATURESEliminates coma, field-curvature and astigmatism in newtonians Diffraction limited performance on axis and in the field Flattens the field Works for very fast systems down to f/3 Four-lens construction Can be used with almost all 2" focusers on the market SCOPE OF DELIVERY High Resolution (HR) Coma Corrector Adaptor to T2 (M42x0.75mm) Adaptor to M48 (M48x0.75) Helical focuser

EXPLORE SCIENTIFIC iEXOS-100 PMC-Eight Wifi Goto Mount
EXPLORE SCIENTIFIC iEXOS-100 PMC-Eight Wifi Goto Mount
The iEXOS-100 is a complete astronomical computerized Wifi or Wired GOTO Equatorial Tracker with integrated PMC-Eight electronics suitable for attaching Small Telescopes or DSLR Cameras attached to a standard Vixen Style Dovetail Plate. Also a ST-4 compatible autoguider port for active tracking control is included. Use with the free ExploreStars App for Tablets (Windows, Android, iOS), or with the free ASCOM Standards Compliant POTH Client from Explore Scientific (either wired or wireless) to work with virtually any sky software that supports ASCOM. The iEXOS-100 utilizes a proven German equatorial mount design and Explore Scientific’s revolutionary PMC-Eight™ motion control system to flawlessly navigate the night sky and track objects as they journey across it. This combination provides superior observing and imaging performance without a prohibitive price tag. GOTO systems play an important role in the world of amateur astronomy because they ensure users spend less time searching for particular objects and more time observing and imaging. The PMC-Eight with its versatile connections supported with free to download apps for Window, Android, and iOS, or through the free to download ASCOM POTH Client to connect to your favorite ASCOM Compliant Astronomical Software, can allow you to control the telescope from a few feet away or by communicating computer-to-computer with an Internet connection from virtually anywhere in the world. One of the standout features of the iEXOS-100 system is its German equatorial design. When it comes to tracking the stars with a telescope, there is nothing that compares to a German equatorial mount because it will follow objects as they rise in the east and set in the west. For observers, a German equatorial mount makes it easy to keep your celestial target in your eyepiece. For imagers, it helps you avoid common astrophotography pitfalls like field rotation. Before you can track an object, you need to find it, and that objective can be daunting when you’re faced with a vast expanse of inky black sky. The iEXOS-100 puts a powerful GOTO system in your arsenal of astronomical tools that takes the frustration out of navigating the night sky. This integrated version of Explore Scientific’s PMC-Eight™ system transcends the industry standard single processor by utilizing eight CPUs that operate independently of one another to focus on defined functions. This delegation of tasks among the processors results in a system that offers superior responsiveness, efficiency, reliability and astoundingly fast timing intervals for seamless images and accurate tracking. Although it is internally complex, the GOTO system can be easily operated from your own Apple, Android or Windows tablet using the ExploreStars app, which has an intuitive nature that makes it simple and quick to align your telescope, navigate the stars and learn specifics about tens of thousands of celestial objects. This dynamic app is fueled by a database that is routinely updated to ensure it remains a relevant resource. Our commitment to creating a streamlined GOTO mount is obvious in other design choices. The iEXOS-100 has locking clutches that will let you quickly reposition your telescope from one side to the other and an altitude knob for smooth height adjustments. The mount base includes a small polar alignment tunnel that allows users to roughly align their observing setup with Polaris. It also has a simple bubble level that comes in handy when stabilizing your tripod. Other features include a bracket for holding the battery pack, which powers the PMC-Eight system™ through 8 C batteries (not included); two 1 kg counterweights for balancing; and glow-in-the-dark markers on certain points of the mount and tripod so you can stay oriented with your setup at night. The mount is designed to hold up to 5 kg of astronomical equipment.IMPORTANT NOTETo start using ExploreStars app, download the free app and download the celestial data set that contains the astronomical catalogs, reference images, and reference text. Simply by unzipping the ExploreStars folder containing the expanded celestial data set into your Pictures directory, you will expand the native database from a thousand objects to over seventy thousand objects.  SOFTWARE DOWNLOADhttps://explorescientificusa.com/pages/software-and-downloads-for-pmc-eight-systemFEATURESIntegrated Explore Scientific PMC-Eight™ Wifi GOTO systemBeautiful full graphical user interface using our very own ExploreStars OpenGotoWifi controlled by Tablet, Notebook or Desktop PC with 7'' or larger display, and Wifi function (computer device not included)Needed system software of optional computer or tablet: WIN8.1, WIN10+11, iOS, Android 4.4 or higherClassic four-button pattern and virtual joystick for guiding, centering, moving and slewing on the touch screenIntuitive 2 star and 3 star alignment procedure Includes a small polar alignment tunnelStandard Vixen Style Dovetail AdapterMount load capacity up to 5 kgMultiprocessor Micro Controller with 8 CPU´sMicro-Stepper Motors and worm gearsSilent Belt-Drive System Mini-USB port for INDI/ASCOM wired computer connectionST-4 compatible autoguider portINDI and ASCOM Driver available: YES, supports also Pulse-GuidingYOU can write your own code and import it into this softwareGPS-compatible and auto time / date settings are dependent on optional receiver on computer, tablet or phoneGlow-in-the-dark markings on mount and tripodWeight mount-head: 4,0 kg ; weight tripod: 2,5 kgSCOPE OF DELIVERYExplore Scientific iEXOS-100 PMC-8 Wifi Goto MountStainless steel tripod with bubble levelCounter weight 2 x 1,0 kg Battery compartment 12 volts with bracket / (8 x C-Cells not included) Coil-cord for DEC motorGlow-in-the-dark markings on mount and tripodExploreStars Software via download for freeInstruction manualIMPORTANT NOTE: This package doesn´t include any WINDOWS/iOS/Android Computer or Tablet.FAQ / KNOWLEDGE-BASE:  https://explorescientificusa.com/pages/explore-scientific-knowledge-base-and-faqsPMC-Eight GROUPS:  https://espmc-eight.groups.io/g/MAIN
