Testing the C11 without OAG

After cleaning & collimation, I tested the C11 with the Starizona F 7.2 reducer, the ASI183mm (way oversampled obviously), and guiding using a simple external 8×50 guider and the ASI290MC. Just as a test not bad. I’m not convinced the mirror shift did not have influence in this image. Focusing was a pain, needed to be done manually.

A nice little galaxy group in Canes Venatici

This picture was taken arbitrarily in Canes, looking for a test object to verify the corrections I did to the optical train. In the previous image (M3) I noticed some tilted focal plane. That was due to an extension ring which was not tightened enough. The main galaxy here is NGC5353
