4.0 Photographic Set Up and the Tele Vue Imaging System
Tele Vue Imaging System Accessories provide solid threaded connections between components. To use
these accessories requires the insertion of the Imaging System Adapter (ISA) into the focuser. You will find
the ISA in the accessory compartment in the lid of the telescopes case. To install the ISA, first back off the
three Lock Screws far enough to pull the 2” Accessory Adapter out from the drawtube to reveal the 2.4”
diameter. Store the adapter in the accessory compartment in the case.
You will then need to back out the screws further so their ends are flush with the inside diameter of
the End Ring. Insert the ISA and tighten the three Lock Screws located equidistant around the end ring.
Conversion from visual (top) to imaging (bottom) con-
figurations. Remove 2” Accessory Adapter if present
and back off the three lock screws flush with the inside
ring. Insert the Imaging System Adapter and tighten
the three lock screws.

The Imaging System’s threaded accessories provide a variety of options for camera adaptation and
focal length variation. The goal of Tele Vue’s Imaging System is to let you pursue your astrophotographic
passion with ease, by providing accessories designed to work together. The following summary of parts
and pictorial diagram will help you understand each part’s use and its sequence in the chain. Please
note that spacing requirements of any particular camera will need to be met by the appropriate Imaging
System spacer or combination of spacers.
