Description

I decided to try a stacked image of a DSO even though I have know way to guide my telescope. I took 9 unguided one minute exposures of M42 and three dark images and DSS to stack, Microsoft editor for processing and Paint to convert from a TIFF to a JPEG image.

The stars seem to be fairly round so next time I will try to push the massive 30 year old Pentax MS-5 mount a little further and see if it can do 20 unguided 90 second exposures.
