M81 M82 13.5.2011

My first go at these 2 not sure if I'm happy with it or not

30x lights @ iso800 30sec

10x darks @ iso800 30sec

10x bias @ iso800 1/4000 exp

All unguided

Still need to sort flats out

All comments welcome even harsh ones

Look at longer exposures - 2 minutes would allow you to pick out more signal from the noise. The result would be more detail appearing.

The problem is that M81 core will saturate quite quickly so with 5 minute exposures you'd loose the core without additional filters.

im not guiding so 2 mins might be difficult. i tried to drift align for the first time last night but couldnt quite get it right

took some shots at 60 sec but they had quite obvious trails
