Thanks Rick - Iwas just playing at the time and need to get serious. I was amazed at how quickly the stars would move.

Josh, thanks for that and you have come a long way in 12 months.

A strategy for this type of camera would be to expose longer with the lens stopped down to the point where there is no chromatic aberration or coma from the lens (some are fine wide open but these are few and far between) and use lower ISO like 800 (OMD EM5 is rated at ISO826 by DXOMark ( I use the DXOMark sensor rating for highest ISO before image degradation as a guide). That may need 5 minutes of exposure.

You can use long exposure noise reduction or take a few darks and subtract in Photoshop or CCDstack or whatever you use.

Build the image up like any deep sky shot. As always longer exposure builds the signal at a dark site and you can get better and better images by building the signal.

Greg.

Thanks for all the tips Greg as they are much appreciated. Wasnt sure where to start with ISO etc and just had a tripod so had to get something. I swapped to a 180 degree full frame fish eye lens and that showed trailing in a few minutes so I went down to 15 seconds and was amazed at what it captured. Need to do darks and get a small tracker to do these lenses justice as I feel the Olympus and lenses a much neglected.

Ahhhhh David you know Im going to do the opposite but thanks for the laughs and for the loan of the tripod. Glad you got hame safely and I bet you were sharp and keen at work on Monday.
