IC2177 & NGC2359 - A Seagull Hunts for a Rabbit in a Dog's Lair

A little story short: Somewhere in the Canis Major constellation (the Dog's Lair), lives a Seagull who insted of catching fish like a normal one, prefers to hunt Rabbits during the Winter's night sky. This is the legend of the emittion nebulas IC2177 and the NGC2359, also known as the Seagull nebula and the Rabbit nebula (Thor's Helmet in some circules), who lies nearby the star Sirius, in the Canis Major constellation.
My project for this Winter, made through multiple nights since October, with a new approach of making an Hubble Palette using a OSC sensor, with the help of a ASI 533MC Pro and the Optolong L-Extreme F/2 + Astronomik MaxFR SII of 6nm filters.

RGB (CFA + Optolong L-Extreme F/2 High Speed) 300s x 171 F/2.8 - Gain 100 - Bin 1x1 - Offset 70 - Focal Lengh 135mm
RGB (CFA + Astronomik MaxFR 6nm SII) 300s x 36 F/2.8 - Gain 100 - Bin 1x1 - Offset 70 - Focal Lengh 135mm

50 Dark Frames + 50 BIAS Frames + 250 Flat Frames

The Moon was in the first night of acquisition, in the Waning Crescent phase at 10.5% of ilumination, in a Bortle scale of 4 (21.63 Mag/Arc.Sec)

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.
