Description

This is an image I processed for one of my masterclasses at AdamBlockStudios.com . The data was kindly provided by my friend Keith Allred. Although it isn't deep by today's standards (this is an HaLRGB image with around 3 hours in each filter)- the data was wonderful to work with and allowed me to show a number of noteworthy techniques (including inclusion of H-alpha via continuum subtraction, HDRMT, Lab color, GHS stretching and more...)

The class from which this comes is here:

The image was also processed partially using a forthcoming AI-based sharpening tool.
