4 hours 3 min FD timelapse of the Sun in H-Alpha on 25th of February 2023.

Acquisition type: Lucky imaging

Time-lapse animation created from 469 recordings between 09:54 and 13:57UT on February 25th 2023. Each recording was 25 seconds long with a framerate of 30fps (750 frames) and 5 seconds delay between each recording. The total amount of data recorded was 1,42TB.

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 ZWO AM5 mount and guided with a Hinode SolarGuider.

The best 100 frames from each recording was stacked in AutoStakkert!3 before they were aligned, sharpened and contrast-stretched in ImPPG.

Variable seeing and some scattered clouds resulted in 43 recordings having to be tossed during processing.

The final animation was created in PIPP at 20fps effectively compressing the 4 hours 3 minutes of duration down to just 21 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.
