Description

M101

Composite galaxy shot, M101 in Ursa Major.

Three different images/data sets from various setups, spanning almost two years. Had to really dig deep in my pile of dead laptop hard drives and memory cards for this one. :p

Luminance for the main galaxy shot with my ED80, ATIK16HR, mono image then overlaid with colour data from an RC6 and 350D. Then an old wide shot from the ED80 and trusty 350D.

The wide shot was really only to give the main galaxy some sky to sit in, but its actually not bad with some tiny galaxies in there and reasonably low noise.
