Description

The purpose of this group is to encourage engaging debate and fresh ideas on L. Schupmann's medial and brachymedial telescope designs, historical record, construction, and astronomical uses.

Questions regarding the fabrication and testing of Schupmann optics as well as the mechanics of the telescope itself are welcome, but for more general inquires on the optical and mechanical fabrication of telescopes please see www.atmsite.org, the ATM mailing list (see http://www.atmsite.org/contrib/
Poulson/faq/atmsect1.html#11) and the ATM mailing list archive at http://www.atmlist.net/pipermail/atm .

Above right : Minor Planet 5779 has now been named after Ludwig Schupmann!
