Sun in Ha - March 5, 2022 - First Prom Animation

Acquisition type: Lucky imaging

The Sun in H-alpha on March 5, 2022 featured a great prom near the north pole. This animation was made from 23 subs captured at 1 minute intervals over 30 minutes (had to drop a few bad subs). This is my first successful solar animation after a few trials. My first attempts were made using my alt-az solarquest mount and I was not able to get them to properly align using IMPPG. I switched to the AVX equitorial mount and IMPPG had no trouble aligning those.

Imaged with a Lunt LS50Tha (with feathertouch focuser and ZWO EAF), 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). Processed in Registax6 (sharpening). Subs aligned using IMPPG. Animated GIF generated using gifmaker.me.

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.
