3 hours 52 min FD prominence timelapse of the Sun on 4th of April 2023.

Acquisition type: Lucky imaging

Time-lapse animation created from 682 recordings between 06:59 and 10:51UT on April 4th 2023. Each recording was 15 seconds long with a framerate of 60 (900 frames) and 5 seconds delay between each recording.

The recordings where obtained using a Coronado SolarMax 60mm/BF15 w/Beloptik ITF, stopped down to 50mm, Baader 35nm H-Alpha and ZWO ASI 178mm. Everything was mounted on a SkyWatcher SolarQuest Alt-Az mount.

The best 100 frames from each recording was stacked in AutoStakkert!3 before they were aligned and sharpened in ImPPG. The solar disk was then made black and the image was contrast stretched in PhotoShop.

The frames where then scaled down to ~67% and the animation was created in PIPP at 15fps effectively compressing the 3 hours 52 minutes of duration down to just 45 seconds.

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.
