This Package includes a Premium Denk II Binoviewer, 2 SCD Holders, Dual Arm Universal Power x Switch, 2" Newtonian Spacer Tube
assembly, 2" Hollow Nosepiece and 2" Multi-Purpose OCS Cell. A Denkmeier Aluminum case is also provided and the binoviewer and the
binoviewer and other optical elements are protected with machined aluminum caps and machined laser engraved dust plugs for the
eyepiece holders.
Newtonians
The 2" Nosepiece, 2" Newtonian Spacer Tube assembly, and 2" 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 1.2X, 1.8X, and 2.3X by moving the Power x Switch Arms
"IN" and then "OUT" so that three instant magnification settings are possible. The package is shipped in the Newtonian
configuration.
Refractors
The middle Newtonian Spacer Tube is never used with a Refractor. The 2" Multi-Purpose OCS Cell is threaded into the
telescope-side of a 2" star diagonal filter threads. The Binoviewer is then loaded into the eyepiece-side of the star diagonal and
low, mid-range and high magnification will occur when moving the Power x Switch Arms "IN", and then "OUT".
SCTs
Only the binoviewer with Dual Arm Power x Switch and 1.25" or 2" nosepiece is used for reduction and normal magnifications. Move
the Logo-Side Power x Switch Arm "IN" for .6X reduction and "OUT" for 1.15X (normal) magnifications. Move the Non-Logo-Side Power
x Switch Arm IN for .8X reduction. If the 2" Multi-Purpose OCS Cell is threaded to the 2" nosepiece and the Power x Switch Arms
are 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®, and
Classical Cassagrains require the system to be used as if these scopes were refractors. Just follow the Refractor instructions and
remember that the 2" Multi-Purpose OCS Cell must be installed in the star diagonal at all times. Focal reduction cannot be
achieved in such telescopes.
When using telescopes like Questars®, Meade ETX90 and 125s®, Meade Maksutovs, Orion® Maks, Intes Micros® and some others, the
Multi-Purpose OCS Cell should not be installed in the diagonal. Focal reduction is possible when using the Power x Switch in these
telescopes. The 1.25" nosepiece is provided in order to allow scopes with 1.25" focusers to be used. Due to the long focal length,
and small relative aperture inherent to Maksutovs, the two reduction modes of the Denk II Universal Power x Switch are very
desirable for deep sky work. Push the Power x Switch Arms to the IN position for focal reduction. If the Maksutov has a 2" focuser
and diagonal, the 2" Multi-Purpose OCS Cell may be threaded on for 2X magnification. The Power x Switch Arms must be moved to the
"OUT" position.
Coronado Filters
An additional 1.25" accessory for the Coronado BF Filter Diagonals is needed if this system is to be brought to focus in Solarmax
Telescopes®, or refractors equipped with Solarmax Filters. This optional cell is called the #150 1.25" OCS Cell and it threads
into the filter threads on the telescope-end of the 1.25" Coronado Blocking Filter star diagonal. This cell must remain in place
for the binoviewer and Power x Switch to function. When using a Solarmax90 Telescope®, the 1.25" Refractor OCS Cell is
unnecessary because that telescope has a special shortened tube designed to allow the Denkmeier Binoviewer to reach focus (see
January 2004 S&T Magazine Maxscope 90 Hot Product description).
