Thanks Robert. I won`t swear to 20th wave, but it does measure out to better
than 1/8th. It is very smooth and no turned edge at all. I used a Mosby null test
on it this PM and it looked very good. There is a very slight raised area in the
center, but VERY slight. I have the mirror in the scope now waiting for the secondary to arrive
tomorrow or Wednesday. Will do the star testing then. Thanks for the advice, I`ll probably go
ahead with Clausing. I have used him before with a club 14" mirror and we were happy with it.
I just really liked the enhanced coating, that extra 5 or 6 % was appealing, but probably not noticible
except under very perfect conditions.
