Description

Captured this object soon after the rise of Orion and before moonrise between 1 and 2:30 am this morning 22 Oct 2019. First time trying different binning (2x2) which seems to have a positive effect with the ASI294MC Pro especially at debayering (no blue background).

Second time to use guiding and first time with subs exposure this long but wanted to give it a try and see outcome.

Subs: 5 x 600s, 4 x 300s - all at gain 120, camerai cooled to -15C.

Calibration/stacking/processing in Pixinsight and slight curve/level adjustments in Photoshop.
