I recently purchased an old Meade DS-16. Remembering the horror and months of therapy that were required when I discovered that my Hardin Optical DSH-10's primary mirror was ONLY 9-3/4" INSTEAD of 10", I cautiously measured my "new" DS-16's primary... 16-3/16" ! YAY! This means that I went from having ~2.56x the light grasp of the 10" that I now have to having ~2.62x. I'm sure I'll notice that when I'm looking at the moon... :p

What about the light loss from the clips? :mrevil:

Isn't it nice how stuff like that seems to work out in the end? :D

I don't turn down extra aperture... :grin:

I haven't had a chance to try it out yet. It needs some work.

I had the same problem with a few Z10's that I owned. 250mm instead of 254mm. Hardin and Zhumell are built by GSO. But then on the other side my 1976 Coulter 14.25" mirror is actually 14.375" with a full 2" thick glass. Its nice to know we used to get "more" than what we paid for!!! :roflmao:Clear&Darks.
