Sun FD in H-Alpha 30th of March 2022 - 5 hours 18 minutes timelapse - Colorized

Acquisition type: Lucky imaging

This time-lapse animation is made up from 898 recordings. Each recording consisting of 280 frames (20 seconds at a forced framerate of 14fps and 2080x2080 pixels). The recordings ran back-to-back from 09:16 to 14:34 UTC. There was a small hiccup after about 90min (the computer froze) which resulted in about 15min of recordings were lost. A total of 1TB of raw-data was recorded for this time-lapse.

The best (sharpest) 100 frames from each recording was then stacked in AutoStakkert!3 before they were aligned, sharpened, normalized and contrast-stretched in ImPPG. Colorized in PS. The final processing step was downsizing to 980x980 pixels and creating the resulting animation in PIPP at 15 fps effectively compressing the 5h 18m down to 59 seconds.

Solar telescope was mounted on an SkyWatcher AZ EQ6 Pro in EQ-mode and guided with a Hinode SolarGuider. There's a small amount of field-rotation due to a slightly off polar alignment.

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.
