Re: [ATM] Cassegrain, primary mirror perforation size

[Otterstedt@t-online.de (Heiner Otterstedt)]

Hello everyone,

@Richard: Funny, everyone who makes a Cassegrain starts with a computer 
program at first. I did so as well, in order to understand all the 
Cassegrain formulas.:

As far as I can see both our programs show the same results, so I 
suppose they work correct. Thanks a lot for this verification! I 
couldn't find any results for the baffle and perforation sizes. I think 
it is not implemented, or did I overlook it?

@Michael: I tried openOffice on my office computer, but it is not 
working on my age-old laptop in the workshop. As far as I can see the 
openOffice results on my office computer and the results on Google-Docs 
seem to be identical.

Thanks a lot for your replies! Any further comments on my 97mm central 
perforation, however?

Cheers, Heiner
