Description

Two galaxies for the price of one!

After an autumn of hardware problems with my scope I'm happy to say I've finally got back to some imaging.

This is the first time I've attempted a mosaic - not a big one, just the two panes but it was a new challenge for me.

I shot M81 (Bode's Galaxy) - the larger of the two galaxies - one night and shot M82 (Cigar Galaxy) a few nights later.

Integration of M81:
R: 27 x 180s (best 27 of 49 shot)
G: 23 x 180s (best 23 of 46)
B: 28 x 180s (best 28 of 46)
L: 52 x 120s (best 52 of 82)

Integration of M82:
R: 46 x 180s (best 46 of 54 shot)
G: 36 x 180s (best 36 of 42)
B: 34 x 180s (best 34 of 44)
L: 82 x 120s

This gives a total integration time of:
M81: 5hr 38min
M82: 8hr 32min
