I just purchased an AM3 mainly for a compact visual mount. In fact I wish there a way to bypass the connection step (flashing red/green) and just use the hand control as a manual alt-az. HINT!HINT! HOWEVER my investigation into the mount has re-sparked my interest in photography. SO my question is; what Wh power supply should I buy such that in the future I could drive an asiair mini with a 120 guide camera and a basic imager ( nothing too demanding) no extras?
