This is a brand new 2 inch JMI focuser model RCF-1 with "flat" base plate option. It is a reverse crayford design. I purchased it for a project that I have since abandoned. This unit has never even been mounted. It comes in the original foam padded shipping box with all mounting hardware and instructions. My price is $80 which includes shipping in the contiguous 48 states.
Note: photo is of a standard version with radius baseplate. This unit has a "flat" baseplate.
