ADAPTER M74 FEMALE - M63 FEMALE FOR RICCARDI REDUCER

This adapter allows you to connect the APM M63 Riccardi Reducer to Sky-Watcher Esprit 100, 120 and 150 apo telescopes. On the telescope side is an M74 x 1 female thread and on the reducer side is an M63 x 1 female thread.

Designed by legendary optical designer Massimo Riccardi, the APM 0.75x reducer provides a fully corrected field of 40mm and transforms your telescope into a true astrograph. By contrast, the Sky-Watcher reducers only cover a 34mm field, making them unsuitable for use with full-frame sensors.
