I took 27 videos this morning as the weather was really nice. The big filaprom was already past its best views and looked more like a diffuse prom. I intended to record 20 sec videos with about 30 seconds between videos but I put wrong numbers in so I ended up recording 45 sec videos. This resulted in about 7100 frames per each video and more than 16 GB per video so I ran out of disk space after 41 minutes (and only then realized my mistake). So, instead of about a one hour animation this is only 41 minutes.

Exposure time of 6.3 ms with gain 125 in Firecapture and 45 sec videos @ 155+ fps. As usual these were recorded using 8 bit high speed capture mode. Best 400 frames stacked.

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.
Dismissals 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.
