My first "big" project - multisession and multichannel processing.

Kept only 7 hours of data out of total 22, collected over 5 nights.

Processing was done only in PixInsight, without applying color-specific modifications through Curves-transofrmation etc, as I wanted to maintain the colors as they were captured by my scope and camera. Only the saturation was increased just slightly, by repeated application of luminosity layer, to emphasize Ha and OIII emission areas. My [precioussss] Epsilon E160 also did its magic and even helped me record hints of dark nebulosities in M110.

I think, for the first try at such a complex target, I did an acceptable job. But the image has some obvious problems, like Starnet process artifact in M32 and oversaturated cores, background extraction imbalance etc, so perhaps I will try another processing workflow in the future. Would also very much appreciate your advices, hints, criticism etc.

Clear skies!

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.
