Processing of NGC 3981 with PixInsight
In this masterclass, world renowned astrophotographer Adam Block takes you on a journey processing one of his largest projects to date. Included with over 4 hours of in depth tutoring is the enormous 27 hours of total integration time taken using our 1 meter aperture scope (CHI-3) telescope in Chile. The largest aperture combined with such a long total integration provides for some stunning results.

Just curious Adam, was there a reason you decided to manually correct the column defects, as opposed to the using the scripts LinearDefectDetection and LinearPatternSubtraction?
Hi Adam, I really appreciate your effort to walk us through the challenges an image can present and how you approach solving them, including alternative approaches. A tremendous learning experience. Thank you.
Thanks for the detailed tutorial. I prefer detailed tutorial myself. What a journey through the many problems in these pictures. Was very inspiring to see how other people solve this kind of problem. I hope to see more tutorials like this from you.
