I imaged Starburst Galaxy last week. It’s located in Cassiopeia. This was a difficult object to image and process due to this object under heavy light pollution where I live. It has a very low surface brightness. I don’t recommend imaging this object under heavy light pollution. Voyager’s auto focusing is excellent. I used single star Robo Focus auto focusing. One sub resulted low FWHM of 1.75". I would say the average FWHM of 63 subs was about 2.3". Meridian Flip also worked great. Thanks to Leo for making a great automation software.

I will try to image with Ha and blend it with LRGB hoping to bring more details of this object.
Thanks for looking. Clear skies and tiny stars.
