I am looking for a cheap 60mm ~f6 or f7 achomat (preferably in a cell) to make a very portable backpacking scope. Where can I get such a thing? Surplus shed doesn't have exactly that, and Apogee said it would be several months before getting short fl 60mm in. I would have thought this was a simple thing to find.

Thanks,
Charlie

Faster and bigger than you were hoping for, but you may need to compromise in your endeavour. Price seems nice.

Charlie,
My first suggestion would have been Apogee but how about these?
