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" 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. 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

Camera-Adapter M35/T2 for Bresser MC/MCX-100 and MC/MCX-127 Maksutov telescopes The BRESSER Camera-Adapter M35/T2 for MC/MCX100/127 is principally designed to connect a DSLR camera (with appropriate manufacturer-specific T2 T-ring, available separately) to the Bresser MC-100 and MC-127 Maksutov telescopes which have a built-in M35 connecting thread. 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 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 Pollux-II 150/1400 EQ3 Reflector Telescope with Smartphone Adapter & Solar Filter
Explore the beauties of the night sky with this complete telescope set. Everything is included so that you can get started immediately with the fascinating hobby of astronomy: the astronomical reflector telescope with 150 mm aperture and 1,400 mm focal length, the equatorial mount, the tripod and extensive accessories for exciting observations. Especially important for beginners: the system is very easy to use. Particularly the Moon, the planets and the Sun appear impressive through the Pollux-II. Powerful performance for your first celestial observations – the telescope Take your first steps in astronomy with this classic reflector telescope of the "Newton" type. Because it is equipped with an additional lens inside the focuser, it belongs to the group of the so-called "catadioptric" optics. One advantage of this combination of lens and mirror: despite the large focal length, the telescope tube is relatively short and therefore easily transportable. In addition, you can look forward to a comfortable observation position at all times. This is because with telescopes of this design you do not look in at the back of the telescope, but at the front and laterally. So you don't have to bend down, even if the reflector telescope is pointed vertically upwards at the sky. The large aperture of 150 mm collects a lot of light from the celestial objects. In addition, 150 mm aperture and 1,400 mm focal length result in a focal ratio (ratio of aperture to focal length) of 1 to 9.3 (F/9.3). This allows you to enjoy viewing your favourite objects at high magnifications with good contrast. Admire especially the planets or details on the Moon through the entry-level telescope. But also some deep sky objects are very nice to observe: open star clusters, globular clusters and bright planetary nebulae such as the Ring Nebula M57 in the constellation Lyra can be seen beautifully through this astronomical telescope. But how close can you get to the celestial eye-catchers? The 150 mm aperture achieves a resolving power that allows magnifications of up to 300x with sharp images. The technical possibilities go far beyond this – theoretically up to 1,050x using the included accessories. However, as the magnification increases, the sharpness of the image can slowly decrease. In addition, high magnification also requires the right environmental conditions. For no matter through which telescope you look, the air turbulence in the atmosphere (seeing conditions) always influences your observation and magnification possibilities. Note for nature lovers: If you choose a Newtonian telescope like the Pollux-II reflector telescope, you can look forward to a specialist in astronomical observation. However, the image is always displayed laterally reversed as well as upside down, which makes no difference when observing the sky. However, this type of telescope is less suitable for nature and landscape observation during the day. Would you like to use your new telescope for exciting nature discoveries as well? Then we recommend that you choose one of the BRESSER refractor telescopes. Solid base for gazing skywards – mount and tripod Have you found the perfect location for your journey of discovery into the night sky? Then simply mount your astronomical telescope with the equatorial mount on the height-adjustable aluminium tripod. The special feature of this type of mount: after the so-called "alignment", the positioning of an axis parallel to the Earth's axis, the movement of the celestial bodies only has to be compensated for on this one axis. To do this, you simply point the axis approximately at Polaris. This is a huge advantage over the azimuthal mount, where both axes are moved simultaneously. In addition, the two flexible shafts with fine adjustment make adjusting and tracking the telescope very precise and comfortable. And to ensure that accessories are always at hand, they can be stored on the handy shelf between the tripod legs.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! Everything you need, night and day – the accessories The astronomical telescope comes with a wide range of equipment so that you can start admiring the Moon, planets or the Sun straight away. At night, the LED viewfinder helps you keep an overview of the sky. Once installed parallel on the tube and correctly aligned, the small red dot shows you where the telescope is pointing when you look through it. This way, you can align the optics precisely and find celestial bodies more quickly before you then take a closer look with the high magnification. Varying views of the universe: the two eyepieces allow you to marvel at your observation objects in different magnifications. They are simply inserted into the telescope's focuser using their sockets with a standardised 1.25 inch (31.7 mm) diameter. You want to see even more details? Then go for the 3x barlow lens, which triples the magnification of the eyepieces. If you would like to make astronomical discoveries even during the day, use the solar filter to observe the star of our own solar system. It allows you to easily and safely observe sunspots and granulation on the sun. CAUTION: Never point the telescope at the sun without the solar filter! Capture special highlights easily – with the smartphone adapter, you use your smartphone as a camera for your telescope. This way you can quickly take your first photos of the Moon or the Sun, for example, and get started in astrophotography. FEATURES Reflector telescope with 150 mm aperture and 1,400 mm focal length Reflector type catadioptric Well suited for observing the Sun, Moon and planets Height-adjustable tripod with equatorial EQ3 mount Precise adjustment through flexible shafts and fine adjustment in both axes Easy to use, very suitable for beginners Focal ratio F/9.3, therefore good for observing the planets and details on the moon 1.25 inch (31.7 mm) eyepiece focuser Two eyepieces and one barlow lens with 1.25 inch (31.7 mm) extension tubes for different magnifications Safe solar observation with the included solar filter Entry into astrophotography with smartphone camera adapter SCOPE OF DELIVERY Telescope Aluminium tripod Equatorial EQ3 mount Eyepieces: 4 mm and 20 mm (1.25 inch sockets) Barlow lens 3x (1.25 inch socket) LED illuminated dot finder Solar filter Smartphone camera adapter Accessory tray Astronomy software download Instruction manual
