M31 Andromeda Galaxy, M32 and M110 Galaxies in a 4-panel mosaic in L(R+HA)GB.

All imaging took place at my remote observatory at e-EyE, Spain.

This image comprises 76 hours of exposures in 760 exposures in total. It is a 4-panel mosaic captured in both 60 second and 600 second exposure times, with Hydrogen-Alpha captured with 900 second exposure time. In summary:

L (Short) = (30 x 60s) x 4
L (Long) = (30 x 600s) x 4

R (Short) = (20 x 60s) x 4
R (Long) = (20 x 600s) x 4

G (Short) = (20 x 60s) x 4
G (Long) = (20 x 600s) x 4

B (Short) = (20 x 60s) x 4
B (Long) = (20 x 600s) x 4

HA = (10 x 900s) x 4

The short and long exposure times in LRGB were used to bring out the core detail in an HDR image.

Equipment and software used:

Mount: Avalon M-Uno
Telescope: Takahashi FSQ-85ED
Camera: QSI 660wsg-8
Autoguider: Starlight Xpress Lodestar X2
Filters: Astrodon E-Series Gen2 LRGB and Hydrogen-Alpha 3nm
Capture Software: Sequence Generator Pro and PHD2
Processing Software: PixInsight
