Focuser for 90mm refractor
I bought one of those cheap 90mm Dia. F8.8 achromats (and tube) currently advertised on eBay... trouble is, I can't find a METAL focuser/adaptor combination to fit the 89mm (I.D.)/93mm (O.D) tube! Anyone got a (metal) R&P focuser from an 'old' 90mm refractor? Will pay up to $50 for something in reasonable condition... Andrew
