Hi all,

Im trying to capture some flats for my ha data which was through a 5nm filter and im at 10 min exposures and the adu is only at 6000, a long way off the 30000 that im aiming for. Is this normal, should they be this long?
using the same light box, my flats for Lum are 2.5 sec.

Is it ok to capture the flats binned 2x2 and them re sample to 1x1?

thanks
Josh
