Hoegaarden Astronomy & Photography
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.
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
This is a group of galaxies in Leo, the Lion constellation that dominates spring nights. M65, M66 and NGC3628. At distances of 35, 42 and 37 Million light years, they form a fysical group in space Tidal forces rip apart the extremities of NGC3628. The smallest galaxy identified in this image is PGC1423398 at a distance of 2 Billion light years: so glad those fotons travelled that distance in space & time only to get caught in my camera!!
