I got an iOptron SkyTracker to help me with long exposurres with camera and fast lenses to take wide field views of starfields.
The SkyTracker (iOptron website) was made to mount on a normal photographic tripod but I wanted a bit more stability so I made a plate that mount on my old Meade tripod with the SkyTracker on top. This is very solid and I wont have to worry about vibrations or accidentally bumping the tripod out of alignment.
The iOptron polar alignment scope is not the best one in the world and I decided to get close to target with a laser pointer. I made an aluminium bracket for the laser pointer out of two pieces of square aluminium and made sure that the two pieces are perpendicular to each other. It is now a simple matter of clamping the bracket on the SkyTracker body and pressing the laser switch while using binoculars.
If I take care with the alignment I can get a few minutes on a short focal length (14mm) without any star trials. I once got a 10 minute exposure that worked out well but I am sure there was a bit of luck involved at the time.
