M81 and M82 Bode's Nebula in L(R+HA)GB

M81 and M82 Bode's Nebula in L(R+HA)GB.

 

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

 

This image comprises 46 hours, 15 minutes of exposures in 315 exposures in total. LRGB exposures were captured over 600 seconds and Hydrogen-Alpha exposures were captured over 900 seconds.

 

L (Long) = 100 x 600s

L (Short) = 50 x 60s

R = 50 x 600s

G = 50 x 600s

B = 50 x 600s

HA = 15 x 900s

 

The short exposure set of Luminance exposures were captured over 60 seconds in order to produce an HDR image in Luminance to preserve galaxy core detail. The Hydrogen-Alpha data was used to enhance the star formation region detail in the image's Red channel.

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
