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.
