Askar ACL200 Gen. 2 Refractor 50/200 OTA

Description

This isn’t a telescope you look through. The Askar ACL200 Gen. 2 is a dedicated astrograph, a 6-element sextuplet lens built purely for wide-field deep-sky imaging, with a built-in aperture control ring that adjusts from f/4 to f/22 the way a camera lens would.

If you’re expecting an eyepiece, this isn’t the product: there’s no visual observation mode here, no magnification spec, just a compact 1.8kg imaging lens designed to mount on a star tracker or camera-style tripod head. In exchange for giving up visual use entirely, you get a full-frame 44mm image circle and an Arca-Swiss compatible base that fits straight into a photography tripod ecosystem instead of a dedicated telescope mount.

Key Features of Askar ACL200 Gen. 2 Refractor 50/200 OTA

A 6-element sextuplet design with two ED glass elements corrects for both color and field curvature across a full-frame sensor, a level of correction a simple doublet or triplet refractor doesn’t attempt.

• Variable aperture control ring adjusts from f/4 to f/22, letting you trade speed for depth of field like a camera lens
• 6-element sextuplet design with 2 ED glasses corrects color and field curvature together
• 44mm image circle delivers full-frame astrophotography coverage in a 50mm aperture
• Combined Vixen-style and Arca-Swiss base plate mounts on photography tripod heads, not just telescope mounts
• At just 1.8kg, this astrograph travels in a camera bag rather than a telescope case
• Dual helical focusing with coarse and fine adjustments locks focus without a separate focuser assembly
• Integrated lens shade blocks stray light without a separate dew shield accessory
• Needing only 3kg of mount capacity, it pairs with the smallest star trackers on the market

Why Choose the Askar ACL200 Gen. 2

Against every other refractor in this catalog, the ACL200 gives up visual use entirely to focus purely on wide-field imaging, and the payoff shows in the field correction: a sextuplet design with two ED elements handles full-frame coverage that a doublet or triplet visual refractor isn’t built to correct for. The Arca-Swiss compatible base also means it slots into an existing camera tripod setup instead of requiring a dedicated telescope mount.

Applications & Use Cases

Built for wide-field deep-sky astrophotography across large-format or full-frame sensors, this astrograph suits nebula field imaging and dark sky survey work on ultra-portable tracking mounts.

• Astrophotographers who already own a star tracker and want a dedicated wide-field imaging lens
• Photographers crossing over from camera lenses who want Arca-Swiss compatibility
