Great thanks, Richard, for your fantastic SHO data. For me it was a quite challenge to process it. My processing software (Fitswork and MaximDL5 )are outdated and barely could held such huge files. Also the last driver's update change settings for histograms, I realized that when Uwe Deutermann did send me his Pacman 700 Mb. SHO data. My software see the histograms as a very thin line, impossible to do anything before histogram stretch. I use Victor Frankenstein's method by mixing several new and old programs hopefully HE IS ALIVE! Initially I used SiriL to properly stretch histogram (Maxim does the same job with sometimes weird results), the next step - I use Fitswork to remove halos around stars, gradient removal, nebula background flatten, deconvolution, color manipulations, sharpening etc. In the end I use GIMP to fix white balance (works very good ), contrast etc. I do not mask the stars (I really should) and seriously thinking to switch to more advance software as PixInsight and Photoshop.

Description: Learning the PI modules, deconvolution is fantastic in comparison with Fitswork and Maxim, noise wavelets too, I made a bit crispy image (in my opinion) to see how it works with nebula details, very impressive.

Description: re-processing, interesting that the Siril gives better histogram's transformation over Maxim and PI. Colder image but the background is black and the stars are almost white

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.
