Acquisition type: Lucky imaging

The time-lapse animation is created from 337 recordings between 12:02 and 13:55UT on September 17th 2023. Each recording was 18 seconds long with a framerate of 20 (360 frames) and 2 seconds delay between each recording.

The recordings where obtained using a using a TS-Optics 102mm f/11 ED, Altair Astro 115mm TRIBAND H-Alpha D-ERF, Baader 35nm H-Alpha, Baader SunDancer II 3x Telecentric System TZ-3S, DayStar Quantum 0,4å PE and Player One Apollo-M Max mounted on a ZWO AM5 / ZWO TC40 carbon tripod and guided with Hinode SolarGuider.

The 200 best frames from each recording was stacked in AutoStakkert!3 before they were aligned, sharpened and contrast stretched in ImPPG.

The animation was created in PIPP at 12fps effectively compressing the 1 hour 53 minutes of duration down to just 28 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.
