Nice capture Elpajare. That spiral sure has weird looking spiral arms. They don't seem to flow gracefully. Maybe it had been gravitationally affected by another nearby galaxy, or something within.
Interesting!

Thanks for comment Ken. Yes, maybe it was been disturbed in the past. Its arms are not regular.

What software do you use to stack? Is it part of the Infinity software?
I'm curious because it seems it's not doing star registration?

Yes it does. Infinity software is one of the things that makes this camera very advisable for video astronomy. its not its fault I think.
The movement you can see in stars is because a hard wind the day of the picture. My scope is a voluminous newton and the equatorial mount is no so heavy to resist hard vibrations.
