The Focal Reduce probably isn't dodgy Robbie. The "sweet spot" of the reducer is designed to illuminate a chip the size of the original DSI colour (3.7 x 4.9mm), but will handle slightly larger ships (SBIg ST7 etc). Unfortunately your Orion Starshooter has a chip about 20 times the surface area (15.6 x 23.4mm). To fully illuminate that size chip using and SCT you will have to look elswhere for a focal reducer. Actually what you are really after is a Focal Reducer/Field Flattener combination.
