Description

One of the perennial favorites, the Andromeda Galaxy (M31). A widefield LHaRGB image taken with the Rokinon 135mm f2.0 lens and ZWO ASI183MM Pro camera over a few nights in November 2018. The widefield imaging setup was riding piggyback on the Stellarvue APO SVA130T triplet mounted on the Orion HDX-110 EQ-G mount.

The image is a combination of Ha and LRGB data. R channel is a blend of the broadband and narrowband images. The Ha exposures were taken with lens stopped at f2.8 and camera gain 53, while LRGB data was captured at f4.0 and gain 0.

L: 63x180s + 31x240s (@ f4.0, Gain 0, bin 1x1)
Ha: 20x1200s (@ f2.8, Gain 53, bin1x1)
R: 12x600s (@ f4.0, Gain 0, bin1x1)
G: 12x600s (@ f4.0, Gain 0, bin1x1)
B: 13x600s (@ f4.0, Gain 0, bin1x1)

Total exposure: 18.0 hours
