It is normal, per my experience, and that of others, that you need to add a 2"
extension tube at the front of the camera.
Then.... you should be able to focus.
Do you have an extender tube, or know of someone with one that you can try it
out ??
What part of town are you in ?? I am in Tempe if that would help.

I have the mentioned autoguider that is sold as compatible with the 50mm
guide scope. I can’t figure out how to get the StarShoot to be in focus.
I’ve tried using a 26mm eyepiece focused on a tree light as far away as I
can see. That I can focus but just before I reach the end of the focuser
travel. When I put the StarShoot in place of the eyepiece, it’s not in focus
and no amount of adjustment will bring it into focus.
I’ve noticed that there’s quite a bit of backlash in the focus ring on the
guide scope when reversing directions. About a third of a turn before it starts
changing the focus. Is that normal?
If anyone has a procedure for setting up the autoguider with the guide
scope for the first time that might work with my combo, I’d love to hear about
it! I had planned on bringing everything to the “Non-existent ATM meeting”
tonight but that got cancelled. :-) (Hi Paul!) I’d love to get this figured out
before the next ATM meeting.
