G'day all,
I hit a snag. Try to do the mirror cell for my Cass.
The DK Cass. primary has a vortex, and I think for proper collimation
need a lateral adjustment for centering.
I studied Tak's Mewlon300 DK and Takahasi using only a 4" cork pad and a
center hub for a cell. No 9 point floating cell, no lateral adjustment.
The 12.5" mirror is full thickness, just like mine.
Can I get away with it? No edge support? I assume the mirror will sag a bit and get just a bit less correction, which may effect the optimum BFL for the design.
The optics I have is the original AO 12.5" f16 DK Cass.
In that the cell was a wood plank, and the mirror was sit on 3 round bolt.....
Thanks for your help.
Mick.
