It'll be interesting to see how well it holds collimation with that cell setup, is it sitting on bubble wrap?
This is not my mirror just an image I found. I understand many mirrors used for high definition imaging are blacked out along 5mm of the outside edge to improved image quality and nothing to do with bad edges.

Yep sitting on bubble wrap which is what I'll do initially to see how well it works and a number of other options including an 18 pointer.
