AstronSCIENTIFIC ROTARION EyepieceWheel User manual

Congratulations on your purchase of ROTARION!
ROTARION is designed and manufactured to be used
for daytime terrestrial observation and for nighttime
astronomical observation.
ROTARION is a unique device, patented in the
European Union and the United States, to be used
with any telescope with a 2" focuser and four of your
favorite 1.25" eyepieces.
For the first time ever, you can change the power or
magnification of your telescope with just a simple
click, connecting your ROTARION remotely to a
Windows computer with the ROTARION REMOTE
CONTROL software included in this box.
ROTARION makes the eyepiece change easy.
Automatic, quick, and precise without touching the
telescope therefore avoiding disturbances in the
positioning or misalignment of the optical axis
between eyepieces. No more searching in the dark
for your next eyepiece!
The automatic eyepiece change allows you to adjust
the correct magnification on your telescope by
increasing or decreasing the focal length of the
eyepiece used, the "zoom effect".
Re-locate lost objects out of the field of view due to
improper alignment or poor tracking of the
telescope. Quick change to your largest eyepiece in
mm number to maximize visual field and re-locate.
All with a simple Click!
And with the Rotarion automatic eyepiece change
you can use higher power eyepieces than you ever
had before. Now you can discover the joy of bigger
and better views with higher magnification!

A-ROTARION
The EyepieceWheel
1. Introduction
Change the power-magnification of your telescope with a
simple Click.
The AstronSCIENTIFIC’s ROTARION EyepieceWheel is a
universal and automatic eyepiece exchanger. You can
automatically quick-change eyepieces and any other
optics. The eyepiece change is easy, fast, and accurate,
without touching the telescope, and therefore avoiding
disturbances or deviations in the positioning of the optical
axis of the telescope.
2. Selecting your eyepieces for the
ROTARION
Choose 4 of your favorite eyepieces based on a scaling
provided by the mm indicated in each eyepiece. From a
large field of view eyepiece, with the lowest magnification
and greatest number in mm, to the eyepiece with smaller
number in mm, smaller field of view and greater
magnification. It is important that the intermediate scaling
between the mm of each eyepiece is as proportional as
possible.
Example:
As you observe in the data sheet on the following page,
you have 6 available 1.25" eyepieces with different
magnifications (mm) and you select 4 eyepieces so that the
scaling of the magnification between them is as
proportional as possible.

When selecting a proportional scaling, you ensure that
when you order the ROTARION to change an eyepiece, the
next eyepiece will always show you the object you are
observing.
CAUTION: ROTARION is designed to accept 1.25”
eyepieces with a maximum 50mm outer/external
diameter. Depending on combinations with other smaller
outside diameter eyepieces, you may exceed the
maximum outside diameter of 50mm at your discretion
and your responsibility.
3. Mounting your eyepieces in the
ROTARION
Remove the ROTARION from the box and observe the 4
ports:
•Port [PORT-1], 12 hours of a traditional clock (A).
•Port [PORT-2], 3 hours of a traditional clock (B).
•Port [PORT-3], 6 hours of a traditional clock (C).
•Port [PORT-4], 9 hours of a traditional clock (D).

Once the 2 eyepieces with the greatest and the smallest
number of mm and the 2 intermediate have been selected
according to their best proportional scaling, you will align
them from lower magnification (largest mm) to higher
magnification (smallest mm) to verify their differences in
height between them.
The difference in heights between the eyepieces should be
compensated by combining the 5mm, 10mm, and 20mm
M42v0,75 Extenders supplied in the ROTARION threaded
to 3 of the 4 supplied Baader Click-Locks.
You select the largest height eyepiece (in this case the
17mm) corresponding to position number 3 in the series of
4 eyepieces on this page, we will place it in port [PORT-3]
of the ROTARION, corresponding to the Hour 6 of a
traditional clock, unscrewing first the "Extenders"
mounted under the Baader Click-Lock.
1. Unscrew Extenders from 5mm, 10mm and 20mm of
the Baader Click-Lock.

4. Once inserted in the Baader Click-Lock, rotate the
center cylinder of the Click-Lock Baader (4) clockwise
to hold the eyepiece in the Click-Lock eye-cup.
5. You will proceed inserting the following eyepieces of
lowest height, matching the height of the eyepiece
with the necessary "Extenders". Following the
example, you proceed to mount the eyepiece of
lowest height, in this case, the eyepiece of 8mm,
which corresponds to the position 4 of the series of
eyepieces drawn at the beginning of this Section 3, in
the port [PORT-4] of your ROTARION .

6. Note in the drawing of the previous point 5, that the
eyepiece of 8mm mounted in the Baader Click-Lock is
not equal in height to the 17mm eyepiece. Using a
combination of 5mm, 10mm and 20mm available
Extenders, you threaded them into the Click-Lock
Baader of the 8mm eyepiece to match the height of
the 17mm eyepiece. In this case you only need to use
the 20mm Extender, not using the 5mm Extender and
the 10mm Extender. Once the eyepiece has been
installed in its Baader Click-Lock, you proceed to hold
the eyepiece by turning the central part of the Click-
Lock in the clockwise direction, as in the previous
drawing in step number 5.
7. You continue to mount the remaining eyepieces. In
this example, you mount the 28mm eyepiece to the
[PORT-2] port of the ROTARION, corresponding to the
Hour 3 position of a traditional clock, using the extra
"Extenders" to equal the heights of the already
mounted eyepieces. In this case, you only use the
"Extender" of 5mm.

8. Finally, on the following page, you assemble the
remaining eyepiece. In this example, the eyepiece of
least power and greatest number of mm and greatest
field of view, the 40mm eyepiece in port [PORT-1] of
the ROTARION, corresponding to Hour 12 of a
traditional watch. If necessary, you will use the spare
Extenders. In this example, you thread the "10mm
Extender2 in the Baader Click-Lock to match the
height to the rest of the eyepieces.

9. Once all eyepieces have been assembled by
combining the Baader Click-Locks and the 9
"Extenders" included in the ROTARION, it is possible
that you must perform a "fine-tuning" of all final
heights to accurately match the height of the 4
eyepieces mounted on the ROTARION. To do this, you
will use the helical adjustment of the Baader Click-
Lock that has an additional travel of 6-7mm by turning
the top ring (10).

10. You perform the heights adjustments using the top
helical rings of the Baader Click-Locks according to the
previous step 9. In this example, you adjust the height
of the 40mm, 28mm and 8mm eyepieces to equal the
height of the 17mm eyepiece. Note the small
difference in height of the 40mm eyepiece Baader
Click-Lock, before and after the fine adjustment,
indicated by an arrow (10). The result, indicated in the
second figure of this page, are the heights alignment
of the 4 eyepieces mounted in the ROTARION,
indicated with an OK.

11. CAUTION! Once all the heights have been adjusted
by means of the helical adjustment of the Baader
Click-Locks, ensure that the eyepieces are secured to
the Baader Click-Lock by turning the central cylinder
according to the drawing in previous step 4.
12. For the final verification of height adjustment of your
eyepieces, an easy method is to place the ROTARION
and its eyepieces face down on a flat surface, for
example a table, ensuring that the eyepieces are
firmly attached to the Baader Click-Locks as indicated
on previous point 4, to avoid any eyepiece fall.
13. If the ROTARION placed face down on the table is not
stable, you must adjust again the heights between
eyepieces using the helical top ring of the Click-Lock
Baader, as indicated in previous step 10.

NOTE: Currently there are more than 500 models of
eyepieces in the international market and although the
ROTARION has been verified with many models of 1.25”
eyepieces, it is normal to have some unused Extenders. But
it is also possible, although unlikely, that in a particular
case, the differences in height between your eyepieces are
very large and you will need some additional "Extenders",
in addition to the 9 "Extenders" included in the
ROTARION’s box. In which case, in your usual astronomy
store, you should be able to purchase additional
"Extenders" M42x0,75 of different heights, since it is a
standard component.
4. Mounting the ROTARION on your
telescope.
If you have not mounted your four 1,25” eyepieces in the
ROTARION you must follow the previous instructions of
this manual, Chapter A, Sections 2, and 3 which explains
the selection of eyepieces and the assembly of eyepieces
in ROTARION.
After completing the method of selection and assembly of
the eyepieces in the ROTARION, according to Sections 1, 2
and 3, you proceed to mount your ROTARION in your
telescope.
1. Remove the additional 2 "barrel from the box and
thread it to the 2" barrel with retaining ring already
mounted on the ROTARION.

2. Insert the ROTARION into the 2 "focuser female draw-
tube of your telescope and hold the ROTARION to
your telescope by firmly tightening the 2" focuser
screws of your telescope.
3. If you do not find the correct focus point with your
telescope, unscrew the fastening screws of your
focuser (A) and move the ROTARION position on the
2" female draw tube of the focuser (B), sliding it in or
out with care (C). Once the correct focus point is
reached, retighten the retaining screws of your
focuser (A) firmly.

4. Once you have reached the optimum position of the
ROTARION on the 2 "female of your telescope's focus,
use the 2" movable retaining ring (A) in the lower
drawing, unscrewing and re-screwing the micro
screws (B) to “memorize” the correct position of the
ROTARION in your telescope’s focuser.
NOTE: After adjusting the position of the ROTARION within
the 2” female draw-tube of your focuser, your telescope
must allow the focus of the 4 eyepieces by the exclusive
use of the wheel or motor of your focuser. Due to the large
number of types and models of 2" telescopes and focusers
on the market, it is possible that you may not reach focus
with all eyepieces. It can happen with some Newton type
reflecting telescopes or also in some refractor models. In
your usual astronomy store you can find Barlow lenses and
A.

B.

optical path corrector lenses, either "Focal Point
Extenders" or "Path Correctors" for telescopes and
focusers with little focal travel range, or with back-focus
limitations. In the specific case of Newton-type telescopes,
there are several manufacturers of "Coma" corrective
lenses that further extend the focal length of the telescope
by solving the "back-focus" limitations.
Optics such as "Barlows", "Focal Point Extenders" and
"Path Correctors" with focal length extension should be
installed by replacing the (A) 2” barrel in the ROTARION.
AstronSCIENTIFIC cannot recommend specific optics (B) to
increase focal travel due to the enormous number of
eyepiece combinations, its later leveling through the
“Extenders” in the ROTARION and the specific back focus
needs of each telescope. At your usual specialized store,
they can recommend the optics that suits your specific
needs of your telescope.
To reach focus in refractors and Newtonians a 2-inch
Barlow (B) x2, x3 x4 or a combination of them works fine.
