How can I remove a 5mm extension ring that is stuck on my ZWO224MC camera?
I've tried using two rubber strap wrenches, but the pieces are too small to grab a hold of and they just slip.
I tried putting the larger red part in a padded vise and turning the smaller black ring with a pair of channel pliers but
the vise will not hold the ring securely without damaging it. I also tried using pliers to turn the black ring (and red ring)
and that just scratched things up.
