Astrophotography Fit
Best for general deep-sky imaging and visual observing when the mount, camera format, and correction hardware are chosen as one system.
Askar SQA106 Petzval Astrograph sits in the telescope slot for general deep-sky imaging and visual observing. The important buying question is whether the optical design, focal length, and mount demands match the targets you actually shoot.
Treat it as a system component rather than a standalone tube: the mount, corrector, camera, and focusing hardware decide how good the final data can be.
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
