The galactic couple - M81 & M82

Great images Trev, I like the way you got the spiral structure in M82 on the first image, amazing detail for a 90mm scope.

Good stuff Trev,
doesn't the IDAS filter have a green hue to it ?

Thanks guys,

Michael, it was really just as a test of the sensitivity of the Sac10. After a couple of unsucessful attempts at NGC 1977 and the California Nebula I wanted to see how much of a difference binning would make. Quite alot as it turned out. On single exposures it needs about 1/2 the time I think.

It was meant to be a short test but I forgot to turn off the binning for the 200 second exposures :roll:

Dave, actually I think you're right. It is a kind of green-yellowish filter. I must take a look at that file again.
