I love my new scope but although I am purely imaging I have noticed that the fine focus knob slips, like bad.
My purpose was solely to add the ZWO EAF but as far as I can tell the left "coarse" knob does not come off, I see no grub screws on it so I can't use the EAF. After taking the scope out the 1st night I got it I just winged it to test the scope out and it's great, at least for me. But very surprised of how weak the fine focus knob is, the coarse is working as it should. I am waiting on a reply from Mike/Astonomics about what may be wrong.
I have now ordered a Moonlite focuser so I can have my trusted stepper motor focus again, but am curious as to any settings/adjustment that is off for the fine to slip that bad. I would have considered putting the EAF on the fine shaft but can't trust the slippage for my focus to be right. Nice looking focuser on the 102EDL but not up to the task of precise repeatable focus for imaging for me.
