M33 Triangulum Galaxy - Esprit 80 - LRGB - 29.4 Hours

My second take on M33, the first one visible in my gallery from 2017, which was first light with an Esprit 120. This is from a darker location, using an Esprit 80, and a few more years of processing experience under my belt :-) .

The lights were taken with Voyager using my own scheduler which uses "staircase" scheduling, taking R lowest, then G, then B, and L frames closest to transit.

The lights were calibrated with SiriL and AstroPixelProcessor, stacked, light pollution removed and RGB combined in APP. Post processing was done in PixInsight. The L master was treated with Deconvolution and a histogram stretch. The RGB master was background neutralized, photometric color cablirated, and historgram stretch. I then used LRGBCombiation to add the L to the RGB, and applied TGVDenoise. I used Starnet to remove the stars and then boosted color with Curves and Saturation, then added the stars back. Exported a TIFF to Affinity Photo and used their HSL and Vibrance controls to bring out some more color in the galaxy. Back to PI where I used LHE to enhance the dark structures while maintaining some of the core glow of the galaxy. Finally used Bodoni Tools in Photoshop to increase star color and reduce star size.

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.
