Can I please re-open this one?
Likewise, I have a GSO focuser. I am having issues with the fine adjustment knob. It only works if I back the tension screw right off, but this is kinda pointless - because the focuser can no longer bear any weight at these settings.
What could I be doing wrong?
The locking screw is backed right off. Check.
Regardless of how tight I turn the compression screw, the main focuser adjuster knob works (you can see both the L and R sides of the focuser spinning).
When the fine adjustment knob is not working, only the right side spins (one one that I'm turning), and the left side does nothing. When the fine adjustment is working, both the left side and right side spin...
Pls help guys
Thx
Logan.
