"Star" mirror cell for conical newtonian mirrors

Here's a pic of the cell I made for a 10" conical newtonian mirror. The 2 "stars" that comprise the cell are made of 3/4" baltic birch plywood. The smaller star attaches directly to the mirror and the larger one attaches to the tube. The mirror shows no sign of astigmatism when mounted in the tube and cools VERY rapidly. Its a little under 1/2" thick at the edges and 1.7" thick at the center. Vince
