Do you know of any images on the net taken with one of these?

No - sorry Greg,
I made an extensive search with Google & can find nothing.
It seems that the Company that does the polishing - Optiques Fullum -
would do proper Zygo Interferometer tests? - but there is nothing I can find yet.
Dream - does have a Zygo Interferometer on site to test all their mirrors.
After many emails:
It would seem that many of us would have to increase our buying power
by pooling our money together to get a discount on a number of mirrors -
mirrors in bulk.
I am thinking about that to try & get the astronomical price of cellular mirrors down.
I want a 10" f4 because that's the only size that will fit on a low end mount like most of us have - an EQ6 -
( which I have - although it's modified
https://www.flickr.com/photos/247194...in/photostream )
& that the telescope will fit in the back seat of any car to take to a dark site.
I don't want to spend big dollars on a solid heavy mirror &
then within 5 years want to replace it because everyone else has better cellular mirrors
offering greater lightness & much faster cool down times -
to help keep the boundary layer of air steady above the mirror.
That boundary layer problem may not affect deep sky imaging
as much as lucky planetary imaging but I want to find out.
I want to try & be at the cutting edge & not just buy something that's expensive & ready to go
but that everyone else has too.
I would only be repeating their experiment.
Those interested can PM me.
cheers
Allan
