Description

A spectacular group, NGC772 and its interacting companion, NGC770 along with other NGC772 satellites and lots of more distant galaxies in the background. The data for this LRGB image was accumulated over a few nights in October 2019 with my new 250mm f4.0 Lacerta Photo-Newton and ASI183MM Pro camera on the Orion HDX-110 EQ-G mount.

The luminance data was captured with camera gain 0, while the RGB exposures were taken at gain 53:

L: 76x300s (Gain 0, bin 1x1)

R: 27x300s (Gain 53, bin 1x1)

G: 25x300s (Gain 53, bin 1x1)

B: 25x300s (Gain 53, bin 1x1)
