The Standard Refractor Power x Switch Package
See Standard and Denk II Power x Switch Package Manual for more details and pictures after reading the information contained below.
With Refractors
This system is designed for use in a Refractor that uses a 1.25" star diagonal. It also includes a machined adapter called Part T
that allows the 1.25" Refractor OCS Cell to be carried by a 2" star
diagonal. Both the 1.25" and 2" star diagonals must have filter threads
on their telescope side tubes. The patent pending Power x Switch allows
any Refractor to operate at two instant magnifications though some
focus adjustment is necessary. With the Power x Switch Arm "IN", the
magnification will be 1.25X and with the Power x Switch Arm
"OUT", the magnification will be 2.5X. These factors will be
somewhat higher if a 2 star diagonal is to be used.
Coronado Filters
The
Refractor OCS Cell may also be used in Coronado Blocking Filter
Diagonals. These BF diagonals have filter threads on the telescope side
and the Refractor 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 Refractor OCS Cell must be used at all times in either the
1.25" Coronado Star Diagonal or focus and Power x Switching will not be
possible. 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 S&T
Magazine Maxscope 90 Hot Product description in Jan 2004 issue).
With SCTs
This
Package also operates with any SCT. F/10 SCTs will be capable of
achieving .66X focal reduction with the Power x Switch in the IN
position. With the Power x Switch Arm in the OUT position,
magnification will be 1.15X due to the interaction of the SCT primary
and Secondary mirror. If 2X is desired, the Refractor OCS Cell may be
threaded to the binoviewer nosepiece which is threaded for 1.25"
filters as well as the OCS Cell. In this way, 3 magnifications are
possible when using the Standard Refractor Power x Switch Package on
SCTs. In the event that an unusual SCT which does not provide an ample
amount of back focus is to be used, it may be necessary to use this
package in the same way that it is used for refractors. This means that
the Refractor OCS Cell would need to be used in the SCT diagonal filter
threads at all times for focus to be achieved. Focal reduction would
not be possible in this case. For the major brands of SCTs, use of the
OCS cell in the diagonal will not be necessary.
With 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 OCS 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 OCS cell
should not be installed. Focal reduction is possible using the Power x
Switch in these telescopes and because of the long focal length and
small relative aperture of many of these designs, reduction may be very
desirable. Our Patent Pending Power x Switch contains the Star*Sweeper
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 OCS 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 package is 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 (or formerly
Part C) is priced at $29. It threads to the 1.25" nosepiece and then
the 1.25" Refractor OCS Cell is threaded to the opposite end of this
Newtonian Spacer Tube. The Power x Switch will then be functional and a
Newtonian will reach focus at a low and high magnification.
