Freeing off a seized T ring adapter 5mm extension piece from ZWO camera front plate.

I had put a 5mm extension ring directly onto the ZWO camera between the filter drawer and the camera, instead of putting the filter drawer directly against the camera. I was then moving around and trying to adjust the back focal distance as I wasn't convinced I had it correct for my Celestron Edge 11.  Unfortunately the 5mm extension ring wouldn't come off and being so short could really get a could hold of it.  Even plumbers grips wouldn't turn it.... Armed with Sasha's sliders and WD40, problem solved! Note to self: Don't put small extension rings where you can't get a proper hold of them...
