Description

Sky-Watcher’s premiere line of Maksutov-Cassegrain telescopes create a perfect blend of aperture and lightweight portability. This telescope design has a reputation for sharp, high-contrast views, ideal for planetary observation. Maksutov-Cassegrain telescopes serve as an alternative to Schmidt-Cassegrains and Newtonians, and offer astronomers a large visual aperture, high contrast, and long focal length in a compact package. Maksutov’s deliver better planetary detail than other telescopes due to a focal length that’s 5-7 times longer, increasing overall magnification. Maksutov-Cassegrains also use a meniscus-shaped corrector plate, eliminating any spherical aberration caused by the primary mirror. Our Maksutov series telescopes deliver refractor-like views and superior contrast while allowing for larger apertures at a fraction of the cost. Our Maksutov series features a borosilicate primary mirror with an aluminum coating and a quartz overcoat, producing 94% reflectivity. The corrector plate utilizes our proprietary Metallic High -Transmission Coatings (MHTC ), giving visual astronomers professional-grade optics creating a unique viewing experience.In addition to the visual benefits of Sky-Watcher Maksutovs, these serve as excellent optical tubes for imaging planetary, lunar, or solar (with use of a solar filter). For astronomers looking to start in astrophotography, the Sky-Watcher Maksutovs deliver exceptionally long focal lengths, necessary for imaging planetary detail. This provides an increased image scale, forgoing the need of a barlow lens or other accessories that may increase exposure times.As customary with all Sky-Watcher products, the Maksutov series includes a bundle of accessories, including: 28mm 2-inch eyepiece, 2-inch 90-degree star diagonal, and a 9x50 straight-through finderscope.

  • Good scope, but not a good first scope
Style: 150mm Maksutov-Cassegrain
I've been doing astrophotography for 4 years. Glad I got this one now, not first. It's slow, highly powerful, and difficult to use compared to other scopes. But it's great for lucky imaging, and has higher contrast than refractor scopes. Took this shot of the Moon night one. It's 6 close up shots stitched together, lucky imaging, shooting 3000 frames, Exposure per frame: 0.33 ms, FPS: 55, with Player One Uranus-M camera. Stacked 210 frames. ... show more

  • Great Starter Mak
Style: 150mm Maksutov-Cassegrain
Very happy with this scope! The views are nice, and no calibration is needed. The only limitation is it’s light-gathering ability - you can’t really zoom in anymore if you want to be able to see anything unless you’re looking at the moon or possibly planets (haven’t bought the eyepiece yet for this). I bought an eyepiece that lets me zoom in slightly for different objects (like the Hercules Cluster). I’m tempted to try an eyepiece that gives me a wider field of view, but I’m afraid the loss of light wouldn’t be worth it. I can see why the size up from this one is almost twice as much. A good scope regardless though. ... show more

  • No longer made with SCHOTT optical glass...
Style: 150mm Maksutov-Cassegrain
When I first got this telescope, all I had was the AZGTI mount.... It actually was able to hold the scope with a counterweight, the mount was actually accurate in it's goto function as well. Very good scope, no longer uses schot glass though so bad advertising...

  • Horrible packaging, no protection to very fragile item!

Item arrived damaged during shipping, packaging was insufficient, with little to no bubble wrap. I had to provide extra bubble wrap to return this item so that more damage did not Occur to the item during return shipping to seller!

  • An excellent telescope
Style: 150mm Maksutov-Cassegrain
I’ll let the attached pictures do the talking. I purchased this telescope to try it out for deep sky and planetary astrophotography and it is doing a stellar job (no pun intended) Pictures are of Messier 5 globular cluster and Messier 100 Spiral Galaxy. My skies are Bortle 7 and I use a Nikon Z50 unmodified camera. The photos are 132 and 232 stacked 30 second images taken at 3200 ISO. No filter was used ( I tried a light pollution filter but the first images were too dark) ... show more

  • My Purchase Skywatcher Skymax 150 mm Maksutov -Cassegrain
Style: 150mm Maksutov-Cassegrain
A really nice Telescope that is easy to use and has great clarity. I easily swap out my Nexstar 8se and use the standard Celestron mount. Yes, you can mount the 150mm Skywatcher on the same mount. (It was impossible to get this simple straight answer on different treads for some reason.) lol. Saturn, Jupiter and the Moon look splendid as well. Im very new to Astronomy but this device just makes me want to get out and learn more. ... show more

  • Great Scope!
Style: 150mm Maksutov-Cassegrain
So far I am loving this telescope. I have dabbled throughout the years and finally decided to get serious about astronomy. This is miles ahead of anything I have had before including a Dobsonian mount 8" reflector. The images are razor sharp and the stars are bright and crisp. I am just now getting into astrophotography and this along with the Sky Watcher EQM-35 Pro is a great pair. Love this scope! ... show more
