Introducing the 0.8x Reducer for NP Scopes
Model NPR-2073 0.8x Reducer for NP Scopes is specifically designed to be used with the Tele Vue NP127is and NP101is Imaging System telescopes. 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 discontinued NPR-1073 (which worked best up to APS-C sensors). When combined with a Tele Vue Petzval type telescope, NPR-2073 reduces the focal length of the telescope by 20% and makes it that much faster. This increases the telescope's field of view by 25%.
This reducer is threaded on both sides for the Tele Vue Imaging System. It attaches to the Imaging Insert included with the Tele Vue NP127is and NP101is scopes and the other side accepts all the spacers, camera adapters, and thread converters included in the Tele Vue Imaging System.
The NPR-2073 can also be used to enlarge the field of other Tele Vue Petzval type telescopes, but will not provide additional correction for those models. For use on Tele Vue Petzval model telescopes with 2-inch focusers, use Tele Vue Imaging System Nosepiece for 2" Focuser (RAD-1074). The RAD-1074 slides into a 2" telescope drawtube and has a 2.4" Imaging System thread on the other side to accept any Imaging System accessory.
