Description

SHO

Ha Baader 2", 7 nm, 75 x 2 min.

OIII Baader 2", 8,5 nm, 80 x 2 min.

SII Baader 2", 8 nm, 80 x 2 min.

Gain 140/ Off set 25 (unity gain), -13°C - -25°C

Moon ca. 100 %

I wanted to try shooting with the ful moon. OIII was the chalange. I timed the OIII sequence when the moon was low behind the trees.

In my opinion, the short 2 min. exposiores worked better with the bright sky than longer ones.

After stacking the subs, calibrated only with dark frames from my dark library, the data was good enough, so I didn't soot any flats or flat darks, as usual.
