The Askar 107PHQ combines a 107 mm aperture with 749 mm focal length at f/7. Its air-spaced quadruplet optical system contains two ED elements and incorporates field correction for a 44 mm image circle.
Imaging and visual use
At native focal length the optical system does not need an additional field flattener or a single prescribed flattener-to-sensor spacing. Connect the camera within the published accessory-connection limit and bring the target into focus. The connection allowance changes with the chosen rear adapter. Visual use is also supported with a suitable diagonal and eyepiece.
Focusing and camera orientation
A 3.4-inch rack-and-pinion focuser provides coarse adjustment and 1:10 fine focusing. The graduated 360° rotator lets you frame the target without turning the complete telescope. Threaded photographic adapters provide the interfaces listed below, including an internal M48×0.75 filter thread.
Mounting and supplied equipment
The telescope has a retractable dew shield, tube rings, a multifunction handle and a 300 mm Vixen-style dovetail plate. The technical table separates bare-OTA weight from weight with mounting hardware. A matching 0.7× reducer is optional and has its own connection and spacing requirements; it is not part of the standard native optical system.
Askar specifies 749 mm focal length. The unchanged Shopify title says 740 mm. Technical content uses the manufacturer value. Manufacturer optical design is quadruplet with two ED elements.
