Denk II Premium Newtonian Power x Switch Package
See the Standard and Denk II Power x Switch Package Manual for more details and pictures after reading the basic information below.
Newtonian Use
This Package
includes a Premium Denk II Binoviewer with 2 SCD Holders, a Dual Arm
Newtonian Power x Switch, a 2" Newtonian OCS, an aluminum case and a
1.25" nosepiece. The Binoviewer, Power x Switch and Newtonian OCS are
loaded into the 2" focuser of the telescope until the Power x Switch is
flush with the top of the telescope focuser tube. The 2" OCS can expand
if focus is not immediately reached in the low power 1.4X mode
(Logo-Side Arm "IN"). The middle spacer tube has been designed to
increase in length and then be locked in position since focus varies
from telescope to telescope. For telescopes like the Obsession® and the
Discovery® and any other Newtonian where the focal point is located
closeer to the focuser base (single eyepieces need to be racked in
almost completely), the 1.4X version is recommended unless the user is
willing to shorten truss tubes a bit or move the mirror cell forward
toward the secondary (in a solid tube Newtonian).
For those using
telescopes made by Nightsky®, Starmaster® and other companies where the
focus is well out from the focuser base with ample in-travel remaining
after single eyepieces
are focused, a lower power 1.2X OCS is a viable
alternative. This 1.2X Cell offers 1.2X/1.8X and 2.3X when used with
the Denk II Newtonian Power x Switch included in this package. Also see
Denk
II Universal Power x Switch Package information for more details
because the 1.2X cell is standard in that package and an extra spacer
tube is included to make up for the 3/4" focuser travel required.
There will most likely be intrusion into the lightpath when the 1.2X is
used but this will occur in the Lowest Power Mode of the Power x Switch
and the mid and higher Power x Switch settings require racking out of
your focuser. The Denk II Universal Power x Switch Package is
featured in this "Newtonian" product section and is the last Package
choice found. For scopes like Discover and Obsessions, this 1.4X
Newtonain Power x Switch Package is recommended though The Denk
II Universal Power x Switch Package will also allow focus though
intrusion at low and mid powers will be significant. We believe that
the diffraction effects are minimal but we also wanted to point out
that intrusion with the 1.2X optic when used in scopes where the focal
plane is close to the upper cage will be evident.
SCT Use
This
Package will be usable with SCTs and Meade®, Questar®, and Intes Micro
Maksutovs. If the telescope can accept 2 accessories, the OCS must be
unthreaded leaving the 2" nosepiece in the Power x Switch. The
Binoviewer is then loaded into the 2 star diagonal and two levels of
focal reduction result when the Power x Switch Arms are moved to the
"IN" positions, one at a time. Generally, .6X occurs with the Logo-Side
Arm "IN" and .8X occurs when the opposite arm or the Newtonian Power x
Switch is moved to the "IN" position.
Refractor Use
This
package may be used with Refractors also. The large 2" format front
cell called The Multi-Purpose OCS Cell must be threaded into the 2"
Star diagonal filter threads located on the telescope-side star
diagonal tube. The binoviewer is loaded into the eyepiece side of the
star diagonal and the Power x Switch arms will function allowing a low,
mid-range and a higher magnification factor with a single pair of
eyepieces. If a 1.25" star diagonal is being used exclusively, the
1.25" Refractor OCS Cell must be ordered.
Star Diagonals When Used With Refractors
Denkmeier
2" Star Diagonals are ideal for providing a lower-end magnification and
maximum illumination when used with this Package and a Refractor. This
is because the Newtonian OCS Cell included in this Newtonian Package
can be situated very close to the star diagonal mirror. The optic is as
close as possible to the star diagonal mirror because the diagonal
telescope-side nosepiece can be unthreaded and the OCS Cell can replace
it. For added stability, the nosepiece can then be threaded to the OCS
Cell. This allows lowest possible magnifications when the Power X
Switch Logo-Side Arm is moved to the "IN" position. Illumination is
also maximized and the telescope focuser tube position in all Power x
Switch settings is brought inward. This last effect is beneficial for
balance and allows refractors with less overall focuser travel to reach
focus in all three Power x Switch magnification levels. Use of the
Denkmeier Diagonal also allows the OCS Cell to thread to the end of the
Diagonal Nosepiece as an alternative position. If the nosepiece is not
removed from the diagonal and the OCS Cell is threaded to the end,
magnification increases and focuser positions of the Power x Switch
move outward. Any 2" diagonal with 48mm filter threads on the telescope
side tube (Nosepiece) will allow the OCS Cell to install in this latter
position.
Coronado Filter Use
An
optional 1.25" OCS Cell be used if the binoviewer and Power x Switch
System is to be brought to focus in Solarmax Telescopes®, or Refractors
equipped with Solarmax Filters. This optional cell installs in 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 this Package in a Solarmax90 Telescope®, the 1.25" Refractor OCS
Cell is unnecessary because this particular telescope has a special
shortened tube that is designed to allow the Denkmeier Binoviewer to
reach focus (see S&T Magazine Maxscope 90 Hot Product description
in Jan 2004 issue).
