Hi all,
First of all, thank you for replies!
Yes, the image was sent to APOD, I hope that they will find it good enough to publish it.
My goal was to have the most possible details. I tried to adjust the inner core but I'm losing details by the outer regions. It was not an easy target, it is bright, this is why I decided to make shorter exposures about the core and longer about the whole galaxy.
I will try to share a higher resolution image.
Thank you guys!
