Askar SQA60 Pro 60/276 mm f/4.6 is a compact Petzval APO astrograph designed for wide-field astrophotography. Its optical design uses six air-spaced lens elements in a 3+2+1 configuration, including two SD glass elements. Thanks to the self-flattened Petzval design, the telescope supports a full-frame 44 mm image format without the need for an additional flattener.
