Description

The Sun in H-alpha on September 11, 2021.  A magnificent, giant prominence was visible on the Northeastern limb (the largest in years according to spaceweather.com).  Went with the single stack only for this session as this results in better prom images in my experience.

Imaged with a Lunt LS50Tha, 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).
