I continue testing the wonderful Askar SQA 85 mm f/4.8 scope. This time I used the ZWO ASI 183 MC camera with a small pixel of 2.4 µm. The angular resolution became smaller, and the galaxies themselves larger and more detailed. For a short-focal-length telescope (408 mm), it seems to me that a small pixel has an advantage, although of course the ASI 183 MC camera itself is clearly outdated. Before this, I shot with the ZWO ASI 2600 MC (pixel 3.76 µm).
