Could it be that my target street light isn’t far enough away? I was attempting
to get rough focus on a stationary object as I find trying to track a star and
focus at the same time to be very difficult. As in beyond my skill level. Maybe
I should try using the Moon as a target?
It looks like the scope has about 1/2” of focus travel. I “think” I was at the
full extension but it’s hard to tell which way I was without the tape measure.

Hi Mike,
I use this autoguider with an ASI-120MM and have no problem reaching focus
with this setup. Are you closer to being in focus when the focuser is at
its maximum extension (in which case you could try to simply not fully
engage the 1.25" adapter and gain a little bit of travel course by
extending it outside) or when it is at its minimum (in which case you would
need a low profile adapter which would reduce the distance to the CCD chip).

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.
