Have now finished and tested the mirror cell using velcro at the the 60% zone to attach and float the mirror . The images look good at 150x , only had an opportunity to test it on M42 and the pleiades from my verandah. I am quite suprised by the images since the mirror is "
only 17millimetres thick
" and 330mm in diameter. Pictures of the mirror cell are attached .
