Recently there was a request for Oslo files on TCT's, particularly the
Kutter 2 mirror Schief.

I've got that if you'd like to inquire off list.

Also I've modeled a 200 mm f/15 Yolo.

The optical quality makes you wonder why more aren't built, especially
after Jose Sasian's great article ( Telescope making #37) on producing the
toric secondary.  Coupled with flex-mirror technology for the very slight
asphere on the primary, Yolos could be more popular.

I'm hot on a 10" Yolo since my flex-mirror scope came out so well.
