40 minutes timelapse of AR13750, AR13751 and AR13759 in H-Alpha 18th of July 2024

Acquisition type: Lucky imaging

Timelapse animation created from 158 recordings between 14:17 and 14:57UT on July 18th 2024. Each recording was 14 seconds long with a framerate of 82fps (1148 frames) and 1 seconds delay between each recording.

The recordings where obtained using a using a TS-Optics ED 102mm f/11, with an 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 and guided with Hinode SolarGuider.

The best 400 frames from each recording was stacked in AutoStakkert!4 before they were aligned and sharpened in ImPPG. The images was then contrast-stretched in Adobe PhotoShop before deflickering in GBDeflicker. Timestamp annotation was added using IrfanView and the final animation which was created using PIPP at 15fps. This effectively compressed the 40 minutes of duration down to just 10 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.
