The Standard SCT Power x Switch Package
See the Standard and Denk II Power x Switch Package Manual for complete operating instructions and pictures.
With SCTs
This
system is designed for an SCT that uses a 1.25" star diagonal or a 2"
diagonal with 1.25" adapter. The patent pending Power x Switch allows
any typical F/10 Meade® and Celesctron® SCT to operate at two instant
magnifications though some focuser knob adjustment is necessary. With
the Power x Switch Arm "IN", the magnification will be .66X and with
the Power x Switch Arm "OUT", the magnification will be approximately
1.15X (this added magnification is due to the interaction of the
secondary mirror and the primary mirror in an SCT).
Also included
is a thread-on 1.25" 2X Multiplier that attaches to the
binoviewer 1.25" nosepiece via matching threads. It is used with the
Power x Switch Arm in the OUT position and allows a third SCT
Magnification of 2X (F/20) to occur.
With Refractors
This
Package also operates with any Refractor using a 1.25" star diagonal
with telescope-side filter threads. The 1.25" 2X Multiplier Cell must
be threaded into the 1.25" filter threads located on the telescope end
of the star diagonal. Then the binoviewer with the Power x Switch is
loaded into the eyepiece-side of the star diagonal. The refractor will
now operate at a low and higher magnification. The Power x Switch Arm
is in the "IN" position for lower power, "OUT" position for higher
power.
Maks,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" Multiplier Cell must be installed in the star diagonal at all
times.
When using telescopes like Questars®, Meade ETX90 and 125s®, Meade
Maksutovs, Orion® Maks, Intes Micros® and some others, the Multiplier
Cell should not
be installed in the diagonal. Focal reduction is possible using the
Power x Switch in these telescopes and due to the long focal length and
small relative aperture inherent to many of these Mak telescopes,
reduction is very desirable. Our Patent Pending Power x Switch contains
the Star*Sweeper" which creates this focal reduction and taking
advantage of this feature will no doubt prove attractive to you. With
the Power x Switch Arm in the "OUT" position, normal magnifications
will result and by adding the 1.25" Multiplier Cell to the binoviewer
nosepiece and keeping the Power x Switch Arm in the "OUT" position, 2X
magnification will result. These magnification factors are in
comparison to magnification using the same eyepiece as a single the
telescope with no binoviewer.
With Newtonians
If
a Newtonian telescope is added and this Standard SCT Power x Switch
Package is already owned, an additional middle spacer tube may be
purchased that will allow the Newtonian to be used. This item called
the 1.25" Newtonian Spacer Tube (also know as the 1.25" Part C)
and is priced at $29. It threads to the 1.25" nosepiece currently
attached to the binoviewer and then the 1.25" Multiplier Cell is
threaded to opposite end of this spacer tube. The Power x Switch will
then function and a Newtonian will reach focus at both low and high
magnifications. Use the link at the top of this page to view the Manual.
