Acquisition type: Lucky imaging

The Sun in H-alpha on October 6, 2022. Finally returning to the cache of solar image data I need to process after being distracted by planets and comets for a few months...

Imaged with a Lunt LS50Tha (with feathertouch focuser and ZWO EAF), Lunt LS50C compact double stack filter, 2.5x Televue Powermate, ZWO ASI74MM. Imaging train was configured to give ~F/18. Image capture using Firecapture. Stacking in AutoStakkert3 (best 25% of 1000 frames). Panorama generated from 2 sub images using Microsoft ICE. Processed in ImPPG (sharpening). Prom image generated from surface image using curves adjustment in ImPPG. Combined surface and prom images using GIMP.

Original version: Surface (Inverted) image combined with prominence image

Rev B: Surface image combined with prominence (inverted) image

Rev C: 4 sub pano imaged using ASI290MM, combined inverted surface and prom images

Rev D: 4 sub pano imaged using ASI290MM, combined surface and inverted prom images

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
