Prominences on the Northern Limb 14:59 BST 03/04/23

            Taken from Oxfordshire, UK on the afternoon of 3rd April 2023. Because it was mid-afternoon when I started imaging, conditions were not great, but there was some nice activity visible on the Sun, and sunspot group AR13270 was looking lovely in H-alpha.

Taken with a Coronado PST and ASI120MC camera fitted with a 2x Barlow. A 1,000 frame video was taken using SharpCap, then the best 30% or 50% were stacked depending on the quality graph. 
Processing workflow:
RGB alignment in Registax 6
Sharpening using Focus Magic
Remove all colour + processing in Lightroom
False colour added back in using Photoshop CS2
Final tweaks & denoise using Fast Stone Image Viewer
