NGC 521: Spiralness

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 NGC 521. One of the special features of this video is the construction of a generalized script for the intial processing of data in CCDStack. In addtion Adam demonstrates the use of the double color method and the soft light enhancement which are useful for faint and low contrast objects.  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.”
