Hi guys,
A certain astro shop just took delivery of a few 16" LB's. And DAMN if they aren't impressive. You even get a dual speed focuser now, and proper primary collimation knobs instead of screws. PM for details, I don't advertise in the main.
Anybody with knowledge of thin mirror flotation notice anything unusual about the mirror cell, and I'm not referring to the white silatic mirror bonding.

Yep, the inner triangle supports are in the wrong orientation.
WoW! That's actually NOT as big as I imagined it would be, doesn't look like a big leap over the 12"! It's sped up from f5 to f4.5, not f4, that's reasonable I guess, but the primary and bucket alone is a sweet 26kg, vs 16kg of the 12", I'd struggle with that.
Even so, the "truss design" maybe less useful as a point of mobility on this thing since this beast is less "transportable" then the other truss scopes in the range, but even if you don't plan to transport it, what's in the market that can compete with 16" for, what's it gonna be: $3k? Truss or not. Looks amazing.
Why of why do they have to make them so white. Anodizing is naturally dark, it takes work to make it so shiny and silver.??? You can see that beautiful double sided tape used to retain the mirror cell supports in pic3, someone has unstuck them and relocated them wrong. I have seen quite a few 12" mirror cells incorrectly aligned but stuck quite firmly with this tape. My own light bridge was like that. Why so white?
