Hi,

I finnaly acquired an Epson 1650 48bit photo scanner with cheap cost ($850 only). attached pls find one of my wide field photo at orion :

technical data :
canon EOS 66 / 50mm f/1.8 @f/4 and 15min exposure, photo taken at 27Dec at around 2:00am, Vixen polaris mount with celestron CG-4 motor drive. Kodak E200, unsharp mask and slight contrast adjustment via photoshop

the motor drive 's speed was wrong and I need to use a Ss100s as guider. this make me annoyed and mistekenly set the field stop at f/4, instead of f/2
