Description

The Sun in H-alpha on April 28, 2022 featuring the giant AR complex 2993/2994/2995.  This was my last session tracking the progress of this very large group of ARs over the course of a week or so.

Imaged with a Lunt LS50Tha (with feathertouch focuser and ZWO EAF), Lunt LS50C compact double stack filter, 2.5x Televue Powermate, ZWO ASI174MM. Imaging train was configured to give ~F/18.

Image capture using Firecapture. Stacking in AutoStakkert3 (best 25% of 1000 frames).  Full disck panorama generated from 2 sub images using Microsoft ICE.  Processed in ImPPG (sharpening, curves adjustment).

Original version:  Surface (inverted) image
