Description

This was an exciting project for me!

I've never had enough reach to do M51 justice before. This image was created by collecting LRGB exposures (5-minutes each) over several cold nights in March, 2020.

The images were stacked in DeepSkyStacker and processed entirely in Adobe Photoshop 2020.

I've recorded a 30-minute image-processing tutorial of the techniques used for this image that will be live in my image processing guide by the end of this week. If you've already downloaded it, remember to update to the new version (for free) this weekend to find it!
