Dark Nebula Workflow and Free Data You Can Use Right Now!

Показать описание

In this video: I walk through a full processing dark nebula workflow and free data you can use right now! I have been enamored with the Barnard catalog for the past few months. I had failed on a couple attempts to capture dark nebula data that was useable but I finally have some things figured out and I'm happy with the results I'm getting! I wanted to share my processing workflow with you, along with free Barnard 13 data so you can work along with me if you would like to try your hand at processing dark nebula data! I thought it might be interesting to do something a little different, and de-compose my workflow process by working from my final finished image of Barnard 13 and step backwards through each step to the beginning. The decomposition chapter is an overview with some details. Then, I took a deeper dive and worked the processing steps forward from the beginning and show you each tool used and discuss my configurations on these tools for each of the steps.
This also ended up being a @setiv2 (SetiAstro) showcase of Pixinsight scripts because these tools have become core in the tools I like to use within my workflow. What is really cool though is that a lot of these tools are available stand-alone and don't require Pixinight, or any other processing software to run within. This means that no matter what astrophotography processing software you use you can use SetiAstro tools in your workflow! I've also heard some rumors that future versions of Siril may implement SetiAstro scripts! Very Exciting indeed!
I'll post some links below for SetiAstro tools so you can check them out for yourself! Also below you can find a link to my Discord where you can grab free data to practice processing with!
Cheers!
