Classical or DK Cassegrain optical set or scope, 10" or larger

Hi all,

I'm looking for a classical cassegrain optical set, or scope, that is 10" or larger. I will also consider a DK or modified DK or other similar cassegrain. I am not after a Mak or SCT.

Could also be part of a Newt/Cassegrain instrument.

f/ratio, well let me know what you have. f/9, f/12, f/15, f/20, whatever - doesn't matter, just let me know.

Let me know what you have, or if you know of one.

Thanks for looking,

Alex.

Still looking for a set of optics.

If you know of a set or of a scope, let me know and I'll be happy to chase it up.

Thanks for looking,

Alex.

My intention is to build a Nasmyth Cassegrain.

The final design could be an orthodox Nasmyth with the focuser set at the centre of the altitude bearing (alt-az/dob mount), or as a semi-Nasmyth with the focuser set on top of the OTA. Whichever the final configuration, it is intended to make a monster table-top scope that can also be set on top of a tripod or pier.

I'm taking inspiration from a clever Dutchman who also makes his own optics.

Alex.
