This offer consists of three items from OPTEC:
Part No. 17402 f/3.3 Telecompressor System for 2" motorized focuser
Part No. 17415 Mounting Plage for ST237/PixCel 237/255 Cameras
Part No. 17422 Mounting Plate and Kit for ST-7 Camera
The boxes were opened to confirm their condition when I purchased them two years ago, and, alas, never used. I'm asking 50% of what I paid, $150 shipped CONUS.
Thanks for looking,
