Need help with 60F Flat-Field?
The Askar 60F is designed for astronomy enthusiasts who prioritize portability without sacrificing image quality. This compact quadruplet astrograph packs serious optical performance into a travel-friendly package that goes wherever your imaging takes you.
The 60F features a quadruplet optical design with three front elements and one rear element, including one piece of ED glass for effective chromatic aberration reduction. The key advantage is the built-in field flattener - there's no need to purchase an additional flattener or calculate complex back focus distances. Simply attach your camera, achieve focus, and start capturing.
With its 60mm aperture, 408mm focal length, and f/6.8 focal ratio, the 60F supports 44mm full-frame imaging with excellent edge performance. The included photographic extension tube with built-in 2\" filter thread provides M48x0.75 and M54x0.75 adapters for quick connection to DSLRs and astronomical cameras.
For visual observation, 1.25\" and 2\" adapters allow connection to a wide range of eyepieces and accessories.
Despite its compact size, the 60F includes a 2.4\" dual-speed rack-and-pinion focuser with 1:10 fine adjustment and a 360-degree rotator with scale markings. Two finder bases on either side of the focuser provide flexible mounting options for guide scopes and other accessories. The retractable dew shield and matting felt interior help eliminate stray light.
Weighing just 2.5kg for the OTA (3kg with tube rings and dovetail), the 60F travels easily. The 230mm Vixen dovetail includes 1/4\" and 3/8\" screw holes for direct tripod mounting. Professional-grade performance at an accessible price - the 60F is ready for your next adventure.
