Hi guys, nothing fancy here, but I'm excited because it's my first go at a Ha image
Just winged it and took 5 minute exposures, probably not enough, it's pretty noisy, but it showed up nice and bright for short exposures. I see people talking about 20-30 minutes for Ha. Do different objects require more or less time?
Guiding started to play up for some reason, so it's only 50 minutes in total, under a full moon aswel. I guess the more the better. To get a good image would I be right to assume taking more, and longer subs, because the signal is fainter, than if imaging a L sub?
