About this image

My second attempt at capturing & processing a sunspot region using my Lunt LS60THa solar scope with ZWO ASI071MC Pro astro-imaging camera.

Seeing was good but it was a tad windy so I decided to reduce the frame size in order to maximize frame rate and shoot a video image of 5,000 frames. I also carried out a flat calibration and selected, stacked, and processed the best 2,500 frames (Astrostakkert, ImPPG, & Photoshop).

 I also attempted a "white-light" filtered image capture but the wind was blowing my 114mm reflector about something awful - I've still to have a look at the RAW video before I decide whether to attempt to process it.
