IC 10 - Starburst Galaxy in our local group

This is the penultimate image from my Intes MN56 Maksutov Newtonian (127 mm / 762 mm). It is the dim but interesting galaxy IC 10, a very active starburst galaxy in our local group. You must image through the plane of the milky way. Somewhat similar to the small magellanic cloud but packed with Wolf-Rayet stars.I decided to stop at just over 8 hours data, which took 5 weeks due to the weather and an f/6 scope. This week (Aug 24-28) has great weather, but a full moon (and getting first light on another scope), so I called it a day for IC 10 for now.4.2 hours OSC using ASI2600MC Pro, -10C, Gain 100, no filters aside from the UV-IC cut on the camera. Subs were 240 s. Stars as they are.I added 4 hours Ha data using altair quad band filter with the OSC. I extracted Ha (which is noisier than mono due to green and blue pixels ignored) and added the Ha stack with split RGB channels using Astropixel Processor.Gentle tweaks in PS CS5. Bortle 5/6 location with LED street lights pouring in to the backgarden.15 px dither for every frame.Master flat used, no darks.This would be a great target for a f/5 longer focal length system, and Ha (7 nm or narrower), R, G and B filters with a mono camera. Still, I think it came out quite nice.

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.
