This work was done specifically to compare two telescopes using the not very large galaxy NGC 5033 (10.7'x5.3'): the Askar SQA 106 (509 mm f/4.8) and the Celestron Edge HD 8 (1400 mm f/7, with a 0.7 focal reducer). The cameras, however, are different: the Askar used a ZWO ASI 183 MC with 2.4 µm pixels, while the Celestron used a ZWO ASI 2600 MC with 3.76 µm pixels. The integration time is also different: 3 h 30 min for the Askar and 4 h 50 min for the Celestron. I'm not drawing any conclusions—judge for yourself.
