Bode's & Cigar Galaxies

Taken with a ZWO ASI533MC and a 150mm F/5 Newtonian.

Stacked and Ha integrated in Siril.
Asinh Transformation to preserver colors, then Generalised Hyperbolkc Stretch.
In Gimp, I used color curves to pull out the blue and red detail in Bode's and Cigar.
Used G'Mic filters in Gimp (Sharpen [tones], and Equalize Light) to bring out more details.
Cropped in Gimp.

Title: False Color HaRGB

Description: My first attempt at integrating 4' 25" Ha data from an Optolong L-Ultimate. I used the Ha (red) channel as a layer in Gimp in LCh Chroma mode. I don't think it's particularly pretty, but I find it interesting. It does bring out detail in both galaxy.

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.
