This Galaxy that is only 2.3 million lights years away.

Large and bright so a great galaxy to image. Spriral arms, dust lanes and regions of hydrogen gas glowing red, make for a interesting image.

Fog kept at bay by the higher temperature of being in a built up area. The only advantage of imaging from a large town.

Used a photoshop layer mask with an unscretched version of the image. This stopped the galaxy core being too bright and losing some of the faint central detail in the final image.

Increased exposure times to ten minutes to capture as much detail as possible.

Data collected on 2 nights. 13th & 31st October.

LRGB image with 4 hours and 20 minutes of data. 13 x Lum 4 x Red 4 x Green 5 x Blue 10 minute exposures.
