Best for general deep-sky imaging and visual observing when the mount, camera format, and correction hardware are chosen as one system.
Askar 103APO sits in the telescope slot for general deep-sky imaging and visual observing. The useful headline specs are aperture 103 mm, focal length 700 mm, f/6.8.
Camera coverage: Full frame / APS-C / Micro 4/3 with corrector. Image circle: 44 mm. Back focus: 55 mm with optional flatteners/reducers.
Refractors keep the field routine calmer: no regular collimation, predictable cooldown, and a clean path to autofocus and filtered imaging. The tradeoff is aperture and reach.
Weight matters here: 5.5 kg. Leave payload headroom for the camera, guider, focuser, dew control, and cables instead of judging the mount by bare tube weight alone.
Best paired with
Corrected field flattener or reducer when the design requires one
Cooled APS-C or smaller astro cameras matched to the image circle
Autofocus, guide scope or OAG, and a mount with comfortable payload margin
Not recommended for
Large full-frame sensors unless the corrected field supports them
Very small travel mounts near their realistic imaging payload limit
Buyers expecting one telescope to be ideal for every target size
