The Standard Universal Power x Switch Package
See The Standard And Denk II Universal Power x Switch Package
Manual for more details and pictures.
The 1.25" Newtonian Spacer Tube assembly, 1.25" nosepiece and
1.25" Multi-Purpose OCS Cell are used as a single connected unit and
threaded into the Power x Switch. This allows a Newtonian to operate at 1.5X
and 2.5X by moving the Power x Switch Arm "IN", and then
The middle Newtonian Spacer Tube is never used with a Refractor. The 1.25"
Multi-Purpose OCS Cell is threaded into the telescope-side of a 1.25" star
diagonal filter threads. The Binoviewer is then loaded into the eyepiece-side
of the star diagonal and low 1.4X and high 2.5X magnification will then occur
when moving the Power x Switch Arm "IN" and then "OUT". If
using a 2" Star Diagonal. Part T has been provided so that the 1.25"
Multi-Purpose OCS Cell can be threaded into the telescope-side filter threads
of the diagonal. Higher magnifications will result as compared to using this
system in a 1.25" star diagonal.
Only the binoviewer with Power x Switch and 1.25" nosepiece is used for
reduction and normal magnifications. Move the Power x Switch Arm "IN"
for .66X reduction and "OUT" for 1.15X (normal) magnifications. If
the 1.25" Multi-Purpose OCS Cell is threaded to the 1.25" nosepiece
and the Power x Switch Arm is moved to the "OUT" position, 2X
magnification will result.
Maksutovs, Classical Cassegrains, Mewlons, Tec Maks
With any telescope that uses a star diagonal but cannot provide the back focus
necessary for the binoviewer to reach focus, the system is essentially used in
the same way as it is with a refractor. Scopes like Takahashi Mewlons®, TEC
Maksutovs®,Classical Cassagrains, and Tal Klestovs require the system to be
used as if these scopes were refractors. Just follow the refractor instructions
and remember that the 1.25" Multi-Purpose OCS Cell must be installed in
the star diagonal at all times. Focal reduction cannot be achieved in such
When using telescopes like Questars®, Meade ETX90 and 125s®, Meade Maksutovs,
Orion® Maks, Intes Micros® and some others, the 1.25" Multi-Purpose OCS
Cell should not be installed in the diagonal. Focal reduction is
possible when using the Power x Switch in these telescopes. Due to the long
focal length, and small relative aperture inherent to Maksutovs, this is very
desirable for deep sky work. Push the Power x Switch Arm to the "IN"
position for focal reduction. The 1.25" Multi-Purpose OCS Cell may be
threaded on for 2X magnification. The Power x Switch Arm must be moved to the
Coronado Filter Use
This 1.25" Multi-Purpose OCS Cell may also be used in Coronado Blocking
Filter Diagonals. These BF diagonals have filter threads on the telescope side
and Multi-Purpose OCS Cell must be installed when the binoviewer is used or
focus will not be possible. The binoviewer with Power x Switch can then be
loaded in the front of the Coronado Diagonal for H-a use. Operation is
essentially the same as with night use in a refractor. Note: The Multi-Purpose
OCS Cell must be used at all times in the 1.25" Coronado Star Diagonal or
focus and Power x Switching will not be possible. When using a Solarmax90
Telescope®, the 1.25" OCS Cell is unnecessary because that telescope has a
special shortened tube designed to allow the Denkmeier Binoviewer to reach
focus (see S&T Magazine Maxscope 90 Hot Product description in Jan 2004
