Originally was just intended to be the first test of the Baader Herschel Wedge and Celestron Skyris 132M combo, on the first clear day in a while. Luckily there happened to be a couple good sunspot groups (2241 and 2242) at the time.

This being my first solar image at a scale where seeing matters, I'm not particularly skilled with things like wavelet sharpening, so I just applied smart sharpening and unsharp mask in Photoshop until it looked nice to my eyes.
