About this product
Model: tv_NPR-2073_Reducer_0.8x_rf
Part Number: NPR-2073
The Tele Vue NPR-2073 0.8x Reducer is specifically designed for use with Tele Vue NP127is and NP101is Imaging System telescopes.
It minimises vignetting with camera sensors up to 43mm diagonal (full-frame) and replaces the discontinued NPR-1073 (which worked best up to APS-C sensors).
When combined with a Tele Vue Petzval-type telescope, the NPR-2073 reduces the telescope's effective focal length by 20%. This makes the telescope faster and increases the field of view by 25%.
Tele Vue Imaging System Compatible
The NPR-2073 is threaded on both sides for the Tele Vue Imaging System. It attaches to the Imaging Insert included with 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. Back Focal Length spacing for the reducer is included in the instructions.
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. On Tele Vue Petzval model telescopes with 2-inch focusers, use the 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.
