43 min hydrogen alpha time lapse - big file

Acquisition type: Lucky imaging

Wiser than yesterday: Today I remembered to adjust the settings and thus this animation consists of 20 sec data acquisition followed by about 30 sec of idle time. Total of 50 frames and thus around 43 minutes in the life of the sun on June 26th 2022. This is a big file, hopefully it'll show up properly. I combined all the different processings in one file so that they can be seen at once making comparing easy.

There is a bit more noise than usual, but I dno't know the source. It may be due warmer than usual weather as the sensor was operating at 49 degC which is about 10 degC higher than usual. Maybe I need to add some passive cooling sinks into the camera and hope for the best. Or use a small PC cooler with a small fan at low rpms.

Settings as usual: Gain 125 in Firecapture, exposure time of 4.8 ms and around 162 FPS. Best 300 images stacked for each animation frame.

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.
