Explore the sky with the Askar 111F Flat-Field Quadruplet Refractor, a versatile self-flattened astrograph designed for both visual observing and astrophotography.
Features a 111mm aperture, 766mm focal length, and native f/6.9 focal ratio, making it a capable all-around telescope for deep-sky imaging, observing, and even daytime photography.
Built with a quadruplet air-spaced APO optical design, using three front elements and one rear element, including one ED glass element to help reduce chromatic aberration and improve image clarity.

Built-in internal baffling helps block stray light and improve contrast, giving astrophotographers cleaner, more detailed results.
Equipped with a smooth 3-inch rack-and-pinion dual-speed focuser with 1:10 fine adjustment, helping users achieve precise focus for high-quality imaging and observation.
Rear 360-degree graduated rotator allows accurate camera angle adjustment, making framing and composition easier during astrophotography sessions.
Retractable lens hood shortens the telescope for easier storage and transport while keeping the setup sleek and travel-friendly.
CNC-machined tube construction and the classic Askar F-series blue and white finish give the telescope a clean, premium look with dependable build quality.
The handle includes a finder base slot, and both sides of the focuser also feature finder bases, giving users flexible mounting options for finder scopes and accessories.
Includes a long 300mm Vixen-style dovetail plate with 1/4-inch and 3/8-inch screw holes, allowing direct connection to compatible tripods and mounts.
