Re: Another pic. What could I have done to get sharper round stars?

Very nice. ISO 1600 or 3200 would have gotten a much brighter image and consequently allowed a shorter exposure time. ISO200 is too low and ISO400 also too low for this type of work. Its all in the ISO3200 - 6400 x 30 seconds at 14-21mm focal length type shot untracked on a tripod with long exposure noise reduction on or ISO1600-3200 on a tracked mount.

GEM= german equatorial mount - a type of telescope mount that has 2 axes that rotate to match earth's rotation and can point anywhere in the sky.
