The AG Optical Systems 12.5" F6.7 Imaging Dall Kirkham (iDK) astrograph is a premium quality imaging instrument featuring a 50mm flat field free from astigmatism and coma. The outstanding optical performance of the 12.5" iDK is made possible through the use of an integral, permanently aligned field corrector combined with a high quality Dall Kirkham F6.7 optical system. Wide field images are captured with high-contrast details and sharp stars across the entire field of view.

Here are some details on our premium 12.5" Imaging Dall Kirkham F6.7 astrograph:

- Premium 12.5" imaging telescope with low expansion optics
- Best in class quality 96% reflectivity coatings
- Huge corrected 50mm field of view free of coma, astigmatism, and field curvature with RMS radius spot sizes from 1.3 to 4.4 microns
- Fastest in class F6.7 focal ratio for 42% more field of view compared to competing CDK F8 systems
- System baffled for big chip cameras (no baffle retrofits on AG Optical iDK scopes, they were designed as big chip astrographs from the start!)
- Rock solid Optec TCF-S3i digital focuser ($1495), Optec Gemini rotating focuser ($3495) options compatible with widely available adapters
- Tip/tilt adjustment focuser base (not found on competing CDK scopes)
- Precision carbon fiber truss tube for mechanical and thermal stability
- CNC machined 6061 anodized aluminum components with all stainless steel fasteners (no worries about rust anywhere on AG Optical scopes)
- Proudly made in the USA by a veteran-owned company with USA-made components (including USA-made, interferometrically tested corrector lenses).

Coming in 2019 is a .75x reducer offering 3.5" of back focus and a 40mm corrected field of view. With the reducer in place the system is taken from F6.7 to F5 while offering generous back focus to accommodate your imaging train. This makes the AG Optical Systems F6.7 iDK scopes extremely versatile.... like having two scopes in one.
