M77: Seyfert Spectacular

This is a legacy video that primarily uses CCDStack and Photoshop with some PixInsight to process the data. Newer videos are found in the PixInsight Edition of the Cosmic Canvas. 

 

This tutorial totals 200+ minutes of instruction as well as the raw data for M77. One of the special processing features in this video is the use of masks (and alpha channels) to display the faint and bright aspects of this galaxy. This technique can be used on most objects that have this typical processing issue. When you complete your own version... you will be one of a very few that show M77 in its greatest glory.  CCDStack, Photoshop CC, and PixInsight are used to process the data.

“The videos are outstanding. I've been using PI exclusively to process my images for some years now and accordingly have some experience and proficiency with the program. Nonetheless, found the videos to be very helpful and informative. Particularly useful are your easy to follow explanations of how the various tools and processes work. I feel certain that these tutorials will significantly shorten the learning curve for both new and experienced users.”
