11.5” f9 Maksutov Cassegrain from zen italy

[stuy]

Hi all!

just acquired this stunning 11.5” Maksutov from Romano zen , being a f9 it’s a compromise of a scope  with a CO of 32% not just a planetary  scope but a bit of an all rounder ( I’m sure planetary will be excellent ) my good friend paul c will make a few bits for it also a carbon fibre dew shield ,Romano has a fantastic reputation for high end optics across Europe he doesn’t make whole tube assembly anymore this is his last one he had il be taking this to Spain next year for 2 weeks with my 10” Mak newt to test and hopefully get some good seeing

The largest I have seen of this type, F9, is fast for these where F20 is not uncommon. Lovely scope I am sure, heavy too I would imagine.

Lovely scope, must be a Rumak design is it? Dont see many non-Gregorian maks around.

Yes Alan it’s 30kg , and craig it’s a rumak design , Romano does do optical sets of Gregory in 12” but you’d have to tube it yourself no mean feat but there are a few company’s than can do it ( watch this space !) stu

I made a few 12" F13.5 Rumak design Maksutov-Cassegrains in the 1980's. They were certainly heavy, the meniscus corrector was around 18mm thick.    😀
