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 !!!

Product information "BRESSER Messier NT-150S/750 Hexafoc EXOS-2/EQ5 Telescope"
NEW – now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. Great telescope for night and solar observation.

The BRESSER Messier NT-150 telescope excels with high rigidity and tack-sharp parabolic optics. The 150 mm aperture enables you to observe bright nebulas in the depth of space. Find the remnants of a gigantic stellar explosion from the year 1054 in the Taurean constellation, or scan the glowing bands of the great Orion Nebula. Detect the famous Whirlpool Galaxy in the Big Dipper or find the Dumpbell-Nebula in the constellation Vulpecula (little fox). The high rigidity of the EXOS-2 mount allows for relaxed observations and is helpful for those making their first attempts at astrophotography.

Please note: Reflector telescopes with optical design Newton are very good for astronomical observing at the starry night sky. But these telescopes are not well usable for observing landscape and nature during daylight. Therefore we suggest BRESSER refractor (lens) telescopes for landscape and nature observing.

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 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. FEATURES Made from high-quality optical glass Filter glass is absolutely parallel All optical surfaces have anti reflex coatings Filter housing from black anodized aluminum Filter threads on both ends (female/male) Multiple filters usage is possible SCOPE OF DELIVERY 4pcs color filter 4pcs protection-case

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

BRESSER Set Microscope Slides
Slides and cover glasses are an indispensable accessory which has also impact on the image quality. For most biological microscopes, the cover glass thickness is an important optical parameter, which is therefore included in the optical design and, if so, printed on the sleeve of every objective. You can usually see the number 0.17 which is the thickness in millimeters. For demanding applications in the laboratory, or for microphotography, using cover glasses with the desired thickness and high quality is necessary.The cover glasses included in the set are made of Boro 3.3 glass and are standardized to a thickness of 0.16-0.19mm. So they match the desired 0.17mm really good and give the best possible image quality. These Boro 3.3 cover glasses are pure white, without streaks and are pre-cleaned and ready to use. They are also especially suitable for fluorescence microscopy.The slides are made of soda lime glass, and have ground edges for safe handling. They have a matte field for writing on both sides (top and bottom). Slides and cover glasses are packed separately and in a vacuum sealed bag, containing moisture absorbent. They can be stored for a long time without loss of quality from hydrolysis and are easy to take out.
