(NPE-1118) 1.5x Extender for Flat-Field Telescopes __

This 1.5x Extender is an Imaging System accessory optimized for Tele Vue NP

"is" telescopes. Perfect for achieving greater image scale and framing smaller

celestial objects. It slips directly into the focuser (without need for imaging

insert) to increase the NP101is scope's focal length to 810mm and the

NP127is scopes to 990mm. The wide 2.4" body is for formats up to 35mm

frame size. Includes ¼" spacer that must be attached for use. If you do not

have one of the configurations listed below, calculate the spacing as follows:

For the NP101is take your camera’s chip to surface plate distance (including

the optical path length of any filters) and subtract it from 87.54mm (3.45”).

For the NP127is subtract from 91.34mm (3.60”).
