Andromeda Galaxy – M31 in LHaRGB

Setup :
– Skywatcher EQM 35 mount driven via EQMOD in NINA
– TS 71 SDQ scope (focal length 450mm)
– ZWO Asi 2600 MC camera (cooled to -10°C, gain 100 and offset 50)
– Siril + PixInsight + Photoshop

Exifs :
– 60 x 300s in RGB with IDAS P3 anti-PIL filter
– 30 x 600s with L-extrem filter
– 20 DOF
– Sky Bortle 5 (Avril, Grand Est, France)

I mixed the two resulting images from each filter to get the best of each: the overall colour with the colour filter, and the detail and red nebulas with the L-extrem filter for the Alpha hydrogen gas areas.
