I have a very good Carton 100mm f11 achromatic objective in a machined cell.
Then there’s a hand picked 1 mtr length of 2mm wall aluminium tube and a TS dual speed focuser. Also a Vixen dovetail and rings ( brand new)
All the main components -only needs an adaptor ring from the objective cell to the tube - to assemble into a very special achromatic telescope.
The components were collected to produce a spectroheliograph.
A change of circumstances and relocation has put the project on the back burner.
If you’re interested in discussing the purchase of these components drop me a PM.
