GSO RC8 Focuser.
Now I've taken a few images with this RC8 I've noticed streaky stars in one corner of the images, see top right in the attached image. If I run the subs through ccd inspector the tilt etc changes depending on how much tension I apply to the set screws on the focuser and which way the filter wheel is pointing. Looks like I need a new focuser before I tackle collimation.
A moonlight with a stepper motor including postage is close to US$500 which is basically half the price of the scope. Is there a cheaper option? Moonlight want US$190 just to add the stepper motor where as a robofocus motor can be had for half that. Has anyone successfully added a robofocus motor to a moonlight focuser?
Alternately, are there any alternatives that I won't have to sell an body organ to buy?
