8_3_2020 Solar animation: takes a while to load to run smoothly

Acquisition type: Lucky imaging

I had very stable seeing in the afternoon (5 pm). I captured 10 second video every 30 seconds (see image for settings) for 45 minutes. I have to adjust the gamma to .93 with my Basler camera otherwise I will clip black point. My capture settings are to optimize the solar surface (there is enough dynamic range to capture prominence) then tone curves to bring out the proms. I am including two different screen shots from ImPPG ( to show the different tone curves for black disk and inverted disk ). I prefer this method over traditional prominence capture because I get better limb activity. To mask the disk I adjust tone curves rather than obscuring it in PS or PI. After aligning in ImPPG, I will make a .gif with PIPP (30FPS rate)

I dont know if I like the inverted disk or the black disk more for animations. I am leaning towards the black disk but since AR 2770 was in the FOV, I included it.

If you enlarge there is some interesting activity at AR2770

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.
