Rho Ophiuchi Complex using a new camera, the ASI071MC

Each year I shoot this target as it's so colorful and interesting. This time, it's using my new ASI071 camera and a Rokinon 135mm lens. This camera is quite impressive as the image has only 20 subs and the only pre-processing was using flats. No darks or bias but I did use dithering during acquisition. I've had to adjust to using a color camera and did struggle with white balance, but found DSS debayer and the RGB channel calibration helped make that easier. I am getting bad halos around stars as I'm using a cheap no name IR-UV cut filter and will be replacing it with something better. I am also having some coma issues from what I think is incorrect backspace distance. I also binned the data when post processing to speed things up. In spite of the issues, the image came out quite well. Offset 10, gain 50. 20x220s.

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.
