Cellular Mirror Availability

[COLOR="Purple"]On a certain large auction site, there is an intersting looking cellular mirror available. This got me thinking about how many cellular mirror manufacturers there are out there. Stabilite is gone. There's Jean-Guy in Canada. Wonder who makes the blank for sale on that other site? Guess I'll ask that question and see what answer I get.

[COLOR="Purple"]Add Lookinglass Optical to the list of cellular makers.

Also, I had a reply from the seller on that big auction site; he makes them himself. I'll ask if any are in use or if is this his first.

I purchased a 16.25" X 3.25" F5 cast cellular mirror that is still catalogued by Edmund Scientific for around $5500.00 Its available in enhanced aluminum or gold. Mine was tested by Paul Z. at the Chabot Telescope Makers Workshop and was better than 1/4 wave (tested to about 1/8 wave but testing conditions are almost always funky with people going in and out}. The face plate is 1.38" thick. The ribs are hex and heavy. Remember this is a cast mirror so everything is unitary, no "real" face plate and ribs. Its completely open in the back.
This is a heavy mirror @ 37 lbs. I think the cellular aspect has more to do with cooling than weight. Its a beautiful mirror.
