0.8x Reducer for NP Scopes

A reducer has the optical property of decreasing the effective focal length of the telescope. Reduced focal length results in wider-field and faster imaging time on nebulae and galaxies. The NPR-2073 0.8x Reducer for NP Scopes was specifically designed to be used with the NP127is and NP101is. While it can also be used to enlarge the field of other Tele Vue Petzval type telescopes, it will not provide additional correction for those models. This reducer was designed to minimize vignetting with camera sensors up to 43mm diagonal (Full Frame) and is a replacement for the previous 0.8x reducer, the NPR-1073, which worked best up to APS-C sensors. When combined with a Tele Vue Petzval type telescope, it reduces the focal length of the telescope by 20% and increases the telescope's field of view by 25%. See instructions for back focal length spacing details.
