Tele Vue IS End Ring Addendum - Manual

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.
