A-ROTARION PHOTO
1. Introduction
Change the power-magnification of your telescope with a
simple Click without touching your telescope and without
touching your imaging equipment!
AstronSCIENTIFIC ROTARION PHOTO is the universal tripod
for imaging equipment with automatic electromechanical
shutter for the ROTARION EyepieceWheel. You can quick
change 1.25· optics automatically in your ROTARION
without touching your imaging equipment.
Also, with the ROTARION PRIMEFOCUS accessory included
in this box, you can change photographic technique with a
simple Click. Replace one of the four optics mounted on
your ROTARION with the ROTARION PRIMEFOCUS
accessory and you can switch from planetary eyepiece
projection to prime focus imaging for deep sky objects. You
only need one telescope, three 1.25” optics and a camera
compatible with both imaging techniques.
2. Read first the ROTARION Eyepiece
Wheel Instruction Manual.
Before proceeding with this ROTARION PHOTO Instruction
Manual, you must perform the ROTARION assembly
according to the instructions in the Instruction Manual of
the ROTARION EyepieceWheel and ROTARION REMOTE
CONTROL software.
In the Instruction Manual of the ROTARION
EyepieceWheel and ROTARION REMOTE CONTROL
software it is indicated how to equal/level in height the
eyepieces and optics mounted in your ROTARION, a

fundamental requirement for the proper functioning of
the ROTARION PHOTO.
Only after having read the Instruction Manual of the
ROTARION EyepieceWheel and ROTARION REMOTE
CONTROL software, after verifying the leveling of heights
of the eyepieces and optics mounted in your ROTARION,
as well as having mounted the ROTARION correctly in your
telescope, and having finally learned the easy use of
ROTARION, continue with the reading of this ROTARION
PHOTO Instruction Manual.
Also, always follow the safety WARNINGS indicated in the
Instruction Manual of the ROTARION EyepieceWheel and
ROTARION REMOTE CONTROL software in addition to the
safety warnings in this manual.
3. Eyepiece Projection Imaging &
Primary Focus Imaging.
Among the different techniques of photography with
telescopes, two of the techniques most used in astronomy
are: 1) eyepiece projection imaging for planets and 2)
prime focus imaging, without eyepieces for deep-sky
objects such as galaxies and nebulae among others.
1. To photograph planets, you will use the eyepiece
projection technique in order to obtain the greatest
magnification in your telescope.
This way, although the planets are near objects, they
are small in comparison to the rest of the sky objects,

and for this reason you need the greatest
magnification possible.
Advanced photographers in planetary imaging use
the greatest magnification in the telescope with
eyepieces and / or optical Barlow lenses, and a
technique called image stacking. This technique
consists in the making of films of a few minutes
duration to obtain hundreds or thousands of short
exposure frames. Due to the turbulence of the
atmosphere, only a small percentage of those frames
are good. Using image processing software, only the
good frames are selected and after are stacked,
resulting in a single high-quality image. In the
internet, there is free software for processing and
stacking planetary images such as "RegiStax", among
others, in addition to commercial software.
This stacking imaging technique is also useful in long-
distance daytime and nighttime terrestrial
photography and “digiscoping” with telescope
magnification to minimize the effects of atmospheric
turbulence.
2. To photograph galaxies, nebulae and other deep sky
objects, you will use the prime focus photography
technique without eyepieces, replacing one of the
four eyepieces mounted on your ROTARION with the
ROTARION PRIMEFOCUS accessory included in this
box.
Although deep sky objects are light-years from Earth,
its size in the sky is very large and therefore no
increase in magnification is needed with eyepieces on
the telescope, as they reduce the field of view.

For this prime focus photographic technique without
eyepieces in the telescope there are a few very long
exposures images, which are then stacked with image
processing software. On the internet you can find
free software, as well as better known commercial
image processing programs such as MaximDL and
others.
With large focal-length telescopes, such as the
popular reflectors Schmidt-Cassegrain, Ritchey-
Chretien, Maksutov and other refracting telescopes,
a "Reducer" or "TeleCompressor" focal-reducing lens
are normally used with this imaging technique to
photograph deep sky objects. The advantages of
using this type of optics are the reduction of the focal
length of the telescope and the increase in the field
of view. Reducing the F number of the telescope
reduces the exposure times of the camera, and the
overall time of the imaging session. You can replace
an eyepiece mounted on the ROTARION by focal
reducer optics at your own discretion.
The ROTARION PRIMEFOCUS accessory for primary
focus photography mounting on the ROTARION
EyepieceWheel and the ROTARION PHOTO is
explained later in this manual.
If you are starting in astro-photography we recommend
that you begin with the single image shooting technique
until you master the operation of your telescope and your
imaging equipment.
Finally, although in the market there are cameras and
other specialized imaging equipment for each imaging
technique, we recommend beginning with multipurpose
cameras, compatible with both photographic techniques
such as DSRL and others until you choose your
specialization.

4. Verification of your optics
assembly in the ROTARION.
At the end of Section 4 of Chapter C ROTARION
EyepieceWheel and ROTARION REMOTE CONTROL
software Instruction Manual, the mathematical
calculations for the recommended maximum power or
magnification of the eyepieces for your telescope are
explained.
As you can see in the example of the following data sheet,
you had 6 eyepieces 1,25" with different magnification
(mm), for the initial assembly of the ROTARION you
selected 4 eyepieces, with the scale of the increases and
magnification between them were the most proportioned
as possible.
First, you mounted the largest height eyepiece of the
Selected list, in this case the 17mm eyepiece, and
therefore in the position [POS-3] of the ROTARION

removing the "Extenders" mounted under the Baader
Click-Lock.
•Position [POS-1] ------------------------> (A).
•Position [POS-2] ------------------------> (B).
•Position [POS-3] ------------------------> (C).
•Position [POS-4] ------------------------> (D).
The result after mounting all eyepieces or optics and after
leveling the heights between the optics by adding or
removing "Extenders" to the Baader Click-Locks to increase
or decrease the heights, and also adjusting the heights of
the Baader Click-Locks with the helical top ring as indicated
in Chapter A, Section 3 of the Instruction Manual of the
ROTARION EyepieceWheel and ROTARION REMOTE
CONTROL software, was as follows:

If your ROTARION does not have all the optics leveled in
height, as shown in the previous drawing, you should check
the assembly again. Follow the instructions in the
ROTARION EyepieceWheel and ROTARION REMOTE
CONTROL software Instruction Manual in Chapter A,
Section 3.
If you are only going to make eyepiece projection imaging,
especially suitable for Planetary astronomy photography
and terrestrial photography, skip to Section 7 of Chapter A,
Mounting the ROTARION PHOTO in the ROTARION.
If you wish to install the ROTARION PRIMEFOCUS
accessory on the ROTARION to perform a prime focus
imaging of deep-sky objects too, such as galaxies, nebulae
and others, read the following Section 5 of this Chapter A:
Preparation of the ROTARION for the installation of the
ROTARION PRIMEFOCUS accessory.
5. Preparation of the ROTARION for
the installation of the ROTARION
PRIMEFOCUS accessory.
The ROTARION PRIMEFOCUS accessory kit included in the
box is a 3 piece black anodized aluminum cylinder, height
adjustable with a T2 thread, hollow and without any
internal optics, designed for prime focus imaging of objects
such as galaxies, nebulae, etc.

If you have the ROTARION mounted on your telescope,
now remove it carefully from your telescope and perform
the following operations on a table.
To mount the ROTARION PRIME FOCUS accessory you
must release the [POS-4] position of the ROTARION where
you will install it, selecting and relocating 3 optics or
eyepieces in the ROTARION:
1. First unscrew (A) to remove all the elements of group
(B) that form the eyepiece assembly of the smaller
number of mm eyepiece and greater magnification or
power, Baader Click-Lock and the "Extenders" (if any)
of the [POS-4] position, except the part with ring "T2
male to T2 male" threaded to the red carousel of the
ROTARION.
2. Unscrew and remove the group (C) from the upper
drawing corresponding to the [POS-3] formed by the
eyepiece, the Click-Lock Baader and the "Extenders",
leaving the piece with central ring of double thread

"T2 male a T2 male "on the red carousel of the
ROTARION. See the following drawing:
3. Next, you assemble the previous group (B)
corresponding to the smallest number of mm
eyepiece and greatest magnification, Baader Click-
Lock and the "Extenders" (if any) in the [POS-3] of the
ROTARION, where Before the group (C) was located.

4. Now you remove the group (D) from the position
[POS-2] of the ROTARION, leaving the piece with
central ring of double thread "T2 male to T2 male" in
the red carousel of ROTARION.
5. If you have performed the previous steps 1 to 4
correctly, the result shown in the following drawing
is: ROTARION with the eyepiece named "large field of
view" and greater number of mm and smaller power
in position [POS-1] that you have never removed; In
position [POS-3] the smallest number of mm and
greater magnification eyepiece known as "planetary"
eyepiece; And finally, there are 2 unmounted groups
(C) and (D) of eyepieces, 2 Baader Click-Locks and
some "Extenders".

NOTE: Before mounting the "resolutive" eyepiece in the
position [POS-2] of the ROTARION, you must select the
intermediate eyepiece between the “large field of view"
eyepiece with greater number of mm and smaller
magnification in [POS-1] and the eyepiece with the highest
magnification and the smallest number of mm referred to
as "planetary" in position [POS-3], both already mounted
on the ROTARION according to the drawing on the
previous page.
To do this, you return to our sample data sheet of available
eyepieces. As you can see in the sheet, the eyepiece that
has the best intermediate scale between 40mm and 8mm
is the 17mm eyepiece.
When selecting proportional scaling, you ensure that when
you command the ROTARION to change an eyepiece, the
next eyepiece will always show you the object you are
imaging. If scaling between the eyepieces is not
proportional enough and when changing the eyepiece with
the ROTARION REMOTE CONTROL software the object you
were viewing does not appear, you may need to get a new

"resolutive" eyepiece of 1.25", with better scaling between
the "large field of view" eyepiece [POS-1] and the
"planetary" eyepiece in [POS-3].
6. Continuing with the preparation steps of the
ROTARION for the ROTARION PRIMEFOCUS
Assembly, select the 17mm "resolutive" eyepiece
according to the previous example.
In this example, the selected group (C) with the 17mm
"resolutive" eyepiece mounted in the Click-Lock Baader is
located in position [POS-2] and is already leveled in height
with the groups of the 40mm and 8mm eyepieces and you
do not need to add or remove "Extenders". The ROTARION
is ready for mounting the ROTARION PRIMEFOCUS kit.

ATTENTION: If in the previous points 6 and 7 you had
mounted another "resolutive" eyepiece different from the
one of 17mm with different height, lower or greater, when
assembling in the Baader Click-Lock the height of the group
(C) of the [POS-2] position would be different from the
heights of the 40mm and 8mm eyepiece groups plus the
Baader Click-Locks and the "Extenders" in positions [POS-
1] and [POS-3]. Then you would have to readjust all the
heights of all eyepieces and always first mount the largest
height eyepiece plus the Click-Lock Baader without
"Extenders" in the [POS-1], [POS-2] or [POS- 3] of the
ROTARION. Then you should match the other group’s
height of eyepieces plus the Click-Locks Baader with the
available Extenders and the fine tuning of the helical top
ring of the Click-Locks Baader.
NOTE: Replacement of small number of mm or high
magnification eyepieces by Barlow optics, extending the
focal length of the telescope, is common in high quality
planetary imaging. In which case, you may replace the
“planetary” eyepiece. In addition, the ROTARION allows
the assembly of focal reducing optics such as "Focal
Reducers" or "TeleCompresors". In which case, you may
also replace the eyepiece that suits you. It is very
important to respect the distance from the focal reducer
to the camera imaging chip. The supplier of these optics
should provide the optimal distance to the camera.
ATTENTION: ROTARION is designed to accept 1.25" optics
of 50mm maximum external diameter to avoid
interferences in the assembly and operation problems of
ROTARION and ROTARION PHOTO. You may exceed the
maximum outside diameter of 50mm at your own risk and
responsibility.

6. ROTARION PRIMEFOCUS kit
assembly in the ROTARION.
As we indicated at the beginning of Section 4 of Chapter A
of this ROTARION PHOTO Instructions Manual, the
ROTARION PRIMEFOCUS accessory allows you to
photograph deep sky objects.
If you have performed the steps in the previous Section 4,
your ROTARION is ready for installation in the [POS-4]
position of the ROTARION PRIMEFOCUS accessory.
1. Loosen the center ring (A) of the ROTARION
PRIMEFOCUS kit and turn the upper body (B) to
increase the height of the accessory.
2. Mount the ROTARION PRIMEFOCUS in the position
[POS-4] of your ROTARY by screwing it on the T2 ring
of the red carousel and once mounted equal the
height (B) to the rest of the eyepieces or optics and
tighten the center ring (A).
