The Askar 151PHQ combines a 151 mm aperture with 1057 mm focal length at f/7. Its air-spaced quadruplet optical system contains two ED elements and incorporates field correction for a 60 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 adjusts focus. 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 Losmandy-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.
