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mm), it seems to me that a small pixel has an advantage, although of course the ASI 183 MC camera itself is clearly outdated.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