Our 8"aperture deep-sky imaging specialist boasts features usually reserved for much pricier astrophotography telescopes. In fact, the Orion 8" f/3.9 Newtonian Astrograph's powerful imaging performance easily exceeds what's achievable with many premium apo refractors costing thousands of dollars more. Its 8" parabolic primary mirror has 800mm of focal length, making the fast f/3.9 Newtonian an ideal wide-field astrophotography telescope. A substantial 70mm minor axis secondary mirror provides full field illumination to CCD and/or DSLR cameras for efficient astrophotography performance. Both primary and secondary mirrors boast enhanced reflectivity (94%) aluminum coatings with a protective silicon dioxide (quartz) overcoat. Three easy-grip, push-pull collimation hand knobs on the primary cell make collimation adjustments easy. Once aligned, three locking thumbscrews secure the 8" parabolic mirror. Images acquired with the 8" f/3.9 Newtonian Astrograph will exhibit maximum contrast thanks to sophisticated telescope features any astrophotographer will appreciate. Nine precisely positioned baffle rings along the inside of the reflector optical tube minimize internal reflections of pesky off-axis light for pristine imaging performance. To further optimize contrast and avoid off-axis light intrusion near the front of the telescope, the dual-speed 2" Crayford focuser has been installed a full 6.3" back from the front of the 30" long reflector optical tube.

Also, i'm a bit of an Orion fan boy...
As most who are viewing this know, astrophotgraphy is is a very expensive, very difficult hobby! I chose this OTA after using the orion sirius mount and canon 60Da DSLR camera for some time with a small beginner 4.5 inch reflector telescope tube. Both of those items were pricey for me, so I was delighted to find a scope specifically geared for astrophotography for $500! Let me tell you... Even if I spent twice that, I would be thrilled with the scope. The focuser is incredible. Having the ability to make small, smooth adjustments and then lock it in is a huge aide. I consider myself to be a beginner astrophotographer who had an above average knowledge of the night sky. Within the first night of use, I was able to take over an hours worth of images of DSO's including the Orion Nebula, andromeda, rosette nebula and even got some cool shots of saturn showing many, many moons!
The only drawback for me was the finderscope; I was used to using small, lightweight red dot finders with adjustable light, and after one night using the included finder, I removed it and plopped on the Orion deluxe red dot finder from my dobsonian scope. It's lighter weight - a big deal for me as I know I am pushing the weight of the sirius mount with the scope plus DSLR. I also got a coma corrector; I couldn't spend a lot so I got the GSO version and have been very pleased so far!! It does a great job flattening the field.
I have not used the scope with eyepieces yet but will update his when I do!
Final note: if you are looking to upgrade from beginner gear to dive into astrophotography at a bargain price, this scope is unmatched in quality and value!
