PST clamshell
Discovered during a recent observatory clean-up!
Coronado PST clamshell mounting ring.
Virtually "as new" in box. (as pictured)
Internal diameter is 58mm.
They don't look to be available anymore, but a web search found similar new units selling for $US 70 ++
Asking $A50 (local pickup southern Sydney) will pack & post anywhere in Oz for $15.00
P.S. Could be this ring was used to mount a SM40/60 and SolRanger finder (as pictured). Sorry that I can't give more detail on this.
