Finally got my OAG auto-guiding setup up and running.
The following image was taken on a standard Canon 60D and is made up of 5 x 240s (1600 ISO) and 13 x 600s (800 ISO) subs and darks processed using Fitswork and Photoshop.
My original OAG purchase got lost in the mail (purchased from a member here) and I ended up getting an old Meade OAG which so far has worked ok.
