Hi everyone I imaged Leonard comet 20 subs of 60secs. In LRGB. And after preprocessing using same sub star aligned for all channels, when I combined them a final picture came out. I believe it is because the comet is moving. Does it mean I can’t use mono for comets ? Look at my image LOL

You can use mono cam with comets but it's more work.

What software did you use for stacking ?
