Photographic Set Up and the Tele Vue Imaging System

Tele Vue Imaging System Accessories provide solid threaded connections between components. Use

these accessories requires the insertion of the Imaging System Adapter (ISA) into the focuser. To install

the ISA, first back off the four 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 case so as not to misplace it. You will

then need to back out the screws further so their ends are flush with the inside diameter of the End Ring.

We have found that three point suspension (lock screws set 120

°

apart) is best to hold the ISA flat

and firm against the end ring.

This will require you to re-

move the two button-head Al-

len screws from the end ring

with the supplied Allen key.

These button-head screws are

found below (to the left of)

the upper-left and lower-right

Thumb Screws.

Move the two nearest

thumb screws into these new-

ly revealed holes. You may

remove the lower-left thumb

screw or simply leave it in

place so it is not lost. Make

sure all screws are backed

out enough so that they do

not protrude into the focuser.

Insert the ISA and tighten

the three Lock Screws located

at 1:00, 5:30, and 9:30 (if

you imagine the end of draw-

tube as the face of a clock).

The Imaging System’s

threaded accessories pro-

vide a variety of options for

camera adaptation and focal

length variation. The goal

of the Tele Vue Imaging Sys-

tem is to let you pursue your

astrophotographic passion

with ease, by providing ac-

cessories designed to work

together.
