If you can forgive my dodgy coma correction, this bright target was shot about a month ago on a dark night with 15 second exposures on my QHY 183C and 8" newt.
IMO the data can be better than the quick live stack, where the stacking is time pressured using a limited number of stars. Processing with dedicated software after the event can make it pop a bit more.
Fwiw, I think I was between targets at the time, so let it rock and roll for about an hour... but with bright targets like this, they certainly don't need that level of exposure time to be pleasing. Usually 5-10 minutes can give a really interesting result.
Note: this has been hideously downsampled to fit in the file upload limit. PM me for a full resolution version if you're interested.
