| NOTE |
We recommend using the MFNEX6
MOTOFOCUS for the
Celestron Evolution 9.25 telescope because
that MOTOFOCUS version is much smaller and, depending on the position of the
adjustable optical tube, you may have limited clearance at the base of the
scope.
|
 |
We NO LONGER SELL
a MOTOFOCUS unit for Celestron telescopes with the
rectangular plate at the base of the focus knob (part of
the scope housing). The rectangular plate can be seen in this
picture with our MOTOFOCUS Collar attached. |

* See the picture at left to identify the Round Focusing Knob (left) vs. somewhat

The other "sides" are curved. |
|
14" SCT Exception: It appears that ALL Meade 14" SCTs
have a ROUND knob with a LARGER
diameter
than the smaller SCTs and require the MFMH part number.
To verify this information with your 14" SCT, measure the knob diameter
(see picture).
It should be 0.975". If the diameter is 0.865" then order part number MFHR. |
|
|
NOTE |
The MFMRN (No JMI Hand Unit)
MOTOFOCUS is equipped with a built-in variable-speed adjustment. It plugs
into the telescope base allowing control from the Meade hand unit, with the
following restrictions: Our hand units include an electronic brake which
stops the motor as soon as you quit pressing the keys. Meade systems do not include this brake.
Older LX200 telescopes do not have enough power on the low setting to run a
MOTOFOCUS unit. The high setting works fine and you can vary the speed
using the variable-speed feature of the MOTOFOCUS unit itself.

ETX
Meade ETX-90
(non-EC version), ETX-90EC, ETX-90PE, ETX-105EC, ETX-105PE, ETX-125EC, ETX-125PE
MOTOFOCUS is especially important for the ETX
when viewing near Zenith (in Alt-Az mode) because it is very hard to reach the
focus knob at this position. We use miniature motors (motor and gear box
size is 1" x 0.5" x 0.375"!) for a very small package.
 |
NOTE: Meade modified their ETX
scopes near the beginning of 2014. The newer versions will not
work with our current MOTOFOCUS unit. You can identify the new ETX
version by the emblem on the side of the fork (see picture). |
 |
The hand unit cord is plugged into the side
of the miniature motor assembly.
|
 |
The MOTOFOCUS hardware does not interfere
with vertical operation at Zenith

MOTOFOCUS Conversion Kit
The conversion kit includes all necessary hardware to convert many
current MOTOFOCUS units for use on a different telescope. It does not include
the motor, cable or hand unit.
(Specify information
regarding the ORIGINAL and DESTINATION telescope models.)
CONVERSION RESTRICTIONS:
The conversion kit is for SCT (focus knob push-on style) and
Rack-and-Pinion (pear motor style) MOTOFOCUS units ONLY.
We can convert from one SCT style to another and we can convert
from one Rack-and-Pinion style to another but NOT BETWEEN the
two styles.
We also cannot convert to or from MOTOFOCUS units designed for
Crayford focusers or those with miniature motors. For
example, we cannot convert to or from models designed for the
following: Meade ETX focus knob (not including LS), Single
fork arm NexStar focus knob, Orion StarMax focus knob, Feather
Touch Crayford, William Optics Crayford, GSO Crayford and
Celestron Onyx Crayford.
SCT conversions include (as necessary):
sleeve, collar, coupler, knob, setscrew and hex wrench.
Rack-and-Pinion conversions include (as necessary): bracket, coupler,
shaft expander, setscrew and hex wrench.

What
is MOTOFOCUS?
MOTOFOCUS is a battery operated
hand control with an electric focus motor that attaches to the shaft of a
focuser knob (or the knob itself) for precise, vibration-free focusing
without the need to touch the telescope. It is great for visual and
photographic use and features variable speed for coarse and fine
adjustments. Precise positioning is accomplished through electronic
braking. Mounting is easy and requires no drilling or
tapping. Add the Personal Computer Focus Control (PCFC) or Digital Focus Counter (DFC), for
improved focusing accuracy and repeatability.

Customer
Comments
"Thanks very much for all
your help and support. You've gone over the top to accommodate my
case. And because of that, I would never hesitate to purchase any
product from JMI because now I know that the support service is great.
Thanks again." (J. T. 06/16/2016)
"MOTOFOCUS is an
incredible product for the price. It installed beautifully [and]
works smoothly and quietly. This will provide a quantum leap in
accurate astrophoto focusing for me." (R. P. 04/2014)
"I appreciate all the help I
was given by the employees at JMI, especially...patience with my lack of
expertise and knowledge. This type of professionalism will make me
a return customer." (T. A. L.)
"I handed the MOTOFOCUS
to my husband as soon as I arrived home...and we were both fascinated.
Excellent product, easy installation and now our telescope has been
enormously upgraded." (M. M. D.)
"I purchased two JMI
MOTOFOCUSers and found both to be very high in quality and workmanship,
also fairly priced.... I would recommend JMI products and service to
everyone. This company has its act together." (J. S.)
"Attaching your
MOTOFOCUS for my Williams Optics Microfocuser was simpler than I ever
expected, and it worked like a charm, to boot! Great engineering =
great products !!!" (G. B.)
"I recently purchased
from you a motorized focuser for my ETX-105. It has transformed my
viewing. It is almost like having a new and better telescope.
Congratulations and thanks!" (N. M.)
"An excellent all round
service with great delivery. Many thanks for a great
product." (M. B.)
"... As for the
product, it has made my viewing 110% easier. The MOTOFOCUS is very
easy to install on the telescope. It took me less than two
minutes. I would recommend this item to anyone who owns a Celestron
5, 6 or 8 SE. It will make their viewing experience much easier and
more enjoyable." (T. S.)
"Most of the time,
customers write to complain, but we should write also when
satisfied! I have received my conversion kit and I transferred
flawlessly my C8 MOTOFOCUS to my NexStar 11 GPS. I am very pleased
to see a company that allows its customers to update its product rather
than to force them to buy a brand new one by creating artificial
incompatibilities. Too many times such questionable marketing
practices are used. This is not the case with JMI. One should
note that my C8 MOTOFOCUS was more than 10 years old and still eligible
for an upgrade. Try to get this in the computer world... So
thank you and let me add that the JMI MOTOFOCUS is simply a mandatory
accessory on a telescope. And you can quote me if you
will." (Olivier Sanguy, Editor in Chief of ESPACE Magazine)
"Needed a replacement or
repair on an old MOTODEC and MOTOFOCUS for an old C8. Spoke with the
technician who then sent me the parts I needed and instructions on how to
do my own repairs. Saved me a lot of money. Much appreciated
and everything worked great! That was very good service."
(P. J. H.)
"I am wondering when you
guys are gonna release that cloud filter that allows me to see through the
clouds? j/k ;) You guys are like super heroes in the telescope
world!" (C. F.)
"MOTOFOCUS for my NexStar
8i worked like a charm. Nice bit of engineering and packaging.
(T. U.)
"Just a brief note to
tell you how happy I am with the recent purchase of the JMI MOTOFOCUS unit
for my Celestron 9.25". I have it on a Vixen Sphinx Mount which
is pushing the upper limit of this mount, so an effective auto-focus unit
is a must as it does take some time to dampen any vibrations. Your
unit worked perfectly out of the box and has made it a pleasure to get
[it] accurately focused (and I'm usually far too busy to send an email
like this unless the product really did exceed all my expectations).
(C. E. S. D.)
"Your MOTOFOCUS (MFCREF)
with my Vixen Refractor ED102SS [is] Great!" (J. C.)
"I received the MOTOFOCUS
in the mail yesterday and must say it is fine craftsmanship. ...thanks for
making such a quality item." (D. B.)
"...I've been using one
of your focus motors on my CG-11 for years. I recently converted it
to use on my LX200 with one of your conversion kits. Everything has
ALWAYS worked perfectly. My hat is off to you and your fine
company." (D. A. J.)
"...My
first purchase (from JMI) was a MOTOFOCUS ... I have nerve damage in my
arms and focusing was a real chore. Not any more! I was so
pleased, that when I was looking for an after-market set of electronic
setting circles, I researched them all and purchased the
NGC-MAX..."
(see continuing comments about the NGC-MAX)
(R. L.)
"...BTW, I'm a MOTOFOCUS
owner and it's the best purchase I've made yet. Great products you
have there! Thanks bunches!" (P. L.)
"I don't know how I got
along without (MOTOFOCUS)! ... I love your
products. There ought to be a law requiring all telescope venders to
include a JMI catalogue with every scope." (L. W. D.)
"It is nice to deal with a company
that is sincerely committed to offering a top-quality product and backing
it up with customer service to match. Needless to say, whenever I
need an accessory for my scope, I'll call JMI." (J. E. G.)

Frequently Asked Questions
(FAQ)
|
| Q. |
What
is the difference between a Focuser and MOTOFOCUS? |
| A. |
A
focuser is the mechanical device that moves an eyepiece (or other
equipment) in and out to bring an image into focus. On the other
hand, MOTOFOCUS units are designed to be attached to the shaft of a
focuser knob (or the knob itself) to motorize the movement of the
focuser. It allows the focuser to be moved in or out without
touching it. Touching the focuser usually causes unwanted movement
in the whole telescope. |
| |
|
| Q. |
Are
your MOTOFOCUS motors AC or DC powered? |
| A. |
All
JMI MOTOFOCUS motors are DC powered. The unit designed for the Meade
LX200 plugs into the telescope control panel and is controlled by the
LX200 hand unit. All other MOTOFOCUS units are designed to operate
with a JMI hand unit. These hand units include variable speed
control and electronic braking and are powered by a single 9-volt battery
(or two 1.5-volt AA batteries in a few older hand units). |
| |
|
| Q. |
How
much focusing control does a MOTOFOCUS give? |
| A. |
With practice, you
can move the focuser drawtube in increments much smaller than the thickness of the average
business card. |
| |
|
| Q. |
How
is the MOTOFOCUS unit attached to the telescope? |
| A. |
All
MOTOFOCUS units designed for rack-and-pinion focusers attach the same
way. One of the focuser knobs is removed and the MOTOFOCUS coupler
is pushed over the exposed drive shaft. The motor bracket is then
secured to the focuser. The units made for SCTs are
friction-driven push-on motors that go on and off the focus knob in
seconds for easy storage. |
| |
|
| Q. |
Can I get
some kind of visible readout of drawtube position? |
| A. |
Yes! Simply
order the Digital Focus Counter (DFC) upgrade
at the same time you order your MOTOFOCUS or you can purchase the
Personal Computer Focus
Control (PCFC) system for displaying and controlling the position on a
computer screen. Since the upgrades are
integrated during manufacturing, they cannot be added later. DRO and
DFC upgrades are not available for ETX and NexStar telescopes. |
| |
|
| Q. |
Are
there any telescopes for which you do not make a MOTOFOCUS? |
| A. |
Helical
and slide tube type focusers are not suitable for MOTOFOCUS. We also
do not make a MOTOFOCUS unit for any focuser that is physically unable to
support the system. |
| |
|
| Q. |
Do
you have MOTOFOCUS for telescopes not listed here? |
| A. |
We
have MOTOFOCUS units for many older telescopes. Even if your
equipment is not listed, we may still have parts in inventory.
However, the cost will be much higher than for those shown in our online
store. |
