I took out my refractor this morning and noticed my Starbeam red dot pointer is higher on the clamshell ring than the piggy-back bracket. All I have to do is move the piggy-back bracket where the Starbeam is mounted on the clamshell ring. Then I move the Starbeam to the right ride of the clamshell ring where the piggy-back bracket is. With the bracket nearly at the top of the clamshell ring, the scope should not be in the camera's viewfinder. Thanks to all that responded. Joe, one of the first things I do when I set up is balance the scope in RA then balance the scope in Dec. Otherwise, stars tend to trail when taking photos because of the movement of the scope.

With that solution, I suspect some telescopes may need balance weights. At the back of the tube it's close to the axis and doesn't tend to throw off the 'scope too much. But at the front it may be off balance. Just a thought. -- Joe

But the biggest problem was that my piggy-back adapter is not high enough above the telescope. I got some of the telescope in the lower left corner of the slide.
Had the same problem with my C-8 and later my C-14. In both cases I fixed the problem by moving the piggyback adapter and camera to up near the front of the tube.
