NGC6822 Barnard's Galaxy

Here is an image of NGC6822 Barnard's Galaxy. This is a barred irregular galaxy located about 1.6 million light years away in Sagittarius. It is a member of the local group.

The galaxy spans about 7,000 light years. The galaxy contains roughly 10 million stars along with a large number of active star formation regions as evidenced by the Hii regions.

I have been working on this for some weeks now after doing the capture in June. I decided to try to do the HA and Luminance with a monochrome camera and do RGB with a color camera to see how that would work out. I think this might be a good way to do things as long as one makes certain the cameras are aligned the same way. I learned this the hard way as the orientation of the sensors in these cameras are 90 degrees apart. So this resulted in the image being cropped a lot more than I would have liked. But a good learning experience.

This was somewhat difficult for me to process as I just could not seem to get the color right. I reviewed a lot of images of this and with the understanding of the morphology of the galaxy, I think I am pretty close to how the color should appear. Or at least in the ballpark.

I also wanted to be quite careful with the background with this image. There does appear to be some galactic cirrus or some dust clouds between us and this galaxy and I did not want to kill that by being too aggressive with the background.

Anyway, it was an interesting project and yet another learning experience. I hope you like it and clear skies and good health to everyone...

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.
