Description

The Sun in H-alpha on December 20, 2021 featuring AR 2907/2908/2909 and some huge filaments. 

This was my first use of a ZWO EAF for focusing my Lunt feathertouch focuser and boy I am happy with the performance.  I think these were some of the best focused images I have obtained with the scope.  It's much easier to focus sweep with the electronic focuser and there is no upset to the image stability with hands free adjustments.

Imaged with a Lunt LS50Tha, Lunt LS50C compact double stack filter, 2.5x Televue Powermate, ZWO ASI290MM. Imaging train was configured to give ~F/18. Image capture using Firecapture. Stacking in AutoStakkert3 (best 25% of 1000 frames).  Generated panorama from 4 subs using Microsoft ICE.  Processed in IMPPG (sharpening and curves adjustment).
