I finally gave up on stacking stacked exposures after seeing a side by side from the Hubble site

Read a breakdown on the astrobin forums showing how drizzling beats stacking every time for preserving star color, and now I feel dumb about the 200 hours I wasted before.

Man I felt that one in my soul, I wasted almost a full season on Andromeda before I realized my stars were basically just white blobs. It stings but hey at least we caught it before burning even more time.

That astrobin thread hit me pretty hard too when I saw it a few months back. I'd spent about 150 hours stacking my M31 data the old way before I realized I was basically crushing all the color out of my stars. The side by side comparison with the Hubble processing method was brutal, especially seeing how much faint blue and red detail I'd been losing in the cores. I switched over to drizzling a few weeks ago and it feels like learning a new hobby altogether, but at least I'm not wasting any more clear nights.

Yeah I used to think the old stacking was fine but now I see I was totally wrong, what made you finally switch over?
