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.

NGC3628 and it’s “tidal tail”

It very rarely happens that we ‘ve got 9 nights in a row (around new Moon!) here in Belgium. Next to the main setup I have put the little SharpStar to use to capture- every night 10-minute frames of this area. Even with the Optolong LPS the large field gave a clear gradiënt of light pollution.

Seeing the tail appear after 145 frames made me smile 🙂
So yes it’s possible to capture this feature in SQM 20 type skies, you only need a lot of patience I guess (or a faster scope).
