Zhumell 12 inch dob...primary mirror question
It appears like the only way to get it out is remove the cell which looks easy enough. Six tube screws and the whole thing should lift right out. While doing that, having read about pinched optics due to the rubber mirror clamps being snugged down a little too much from the manufacturer, I'm going to check that while I have it out, using the business card gauge method I've heard about. Can anyone confirm that's the correct tension on those? Out of curiosity also, does anyone know if the Zhumell mirrors are glued/silconed in and not simply held in place by the 3 mirror clamps?
Orion ST80/SLT mount, Meade ETX80, Celestron Omni XLT 150/Orion EQ3 mount, Celestron 6SE, Skywatcher 8" Collapsible dob, Zhumell 12" dob. Boxes and boxes of misc parts, gadgets, and eyepieces....probably a bunch of stuff I forgot I have.

I do not recall anyone mentioning the mirror being siliconed in place.
