GoTo and Tracking Upgrade for Meade LightBridge Meade LightBridge
Dobsonian 12"
The GoTo and Tracking AutoStar™ Upgrade for the LightBridge Telescope
adds hardware and software to transform the Meade LightBridge Telescope into a
Computerized GoTo Positioning and Tracking System. It includes Genuine
Meade and JMI parts. The Meade components includes an AutoStar™ Hand
Control, Software and Motors (including GPS). The JMI
parts include the mounting and drive gear hardware. An upgraded system
uses the AutoStar Hand Control to control virtually every telescope function
from tracking to automatically moving the telescope to one of over 30,000
objects in the database.
Installation requires some drilling of
pilot holes and takes about one hour. Allow an extra hour to read the instructions and
watch the video. Drop-in brackets make removal and re-installation
short and simple.
You must supply the LightBridge telescope or include a LightBridge in your purchase from JMI.

Counterweights
for Meade LightBridge Meade LightBridge
10" / 12" / 16"; Zhumell Z12 Dobsonian
These counterweights help counterbalance heavy equipment at the
eyepiece or on the nose assembly. The clip-style mounting brackets attach to the bottom of the
mirror tub by sliding the
clip onto the mirror cell support. There are two counterweight clips in a
set with each having two weights (approx. 1 lb ea) for a total of
approximately 4 lbs. With each clip you can use a single weight or stack the two
weights together. These counterweights are included with the DELUXE
Transporter Kit (above).

NOTE
|
These counterweights will not work on the
8" LightBridge.

The Train-N-Track (TNT) system is a basic
alt-azimuth motor drive system with adjustable or trainable tracking. A
simple 30-second training procedure allows the scope to track for 10 minutes or
more.
The TNT motor drive system includes adjustable speeds on both axes and high
speed centering. The friction drives also allow you to move the telescope
around by hand without unlocking any clutches. You just let go and the
drive takes over. With a little practice, objects can be kept in the
eyepiece for 10 minutes or more. This version of the TNT is battery driven
with 8 AA batteries.
The TNT system does not interface with any other products.
Installation is easy. You must supply the Astro-Tech Voyager Mount.

What
is a GoTo Upgrade?
The GoTo Upgrade adds
Meade's AutoStar™ Computer Controller to a Meade LightBridge Dobsonian
telescope. The AutoStar adds motorized tracking and GoTo
positioning capabilities. This is accomplished with genuine Meade
parts for the Computer and Software plus JMI parts for Mounting the
hardware and Driving the telescope. The system includes the
following components: Meade's Handbox Controller, Computer
Controller Electronics (including GPS and LNT™ modules) and Motors (with
worm gears) plus JMI's Drive Equipment and Covers. The AutoStar Handbox controls virtually every telescope function
from tracking to automatically moving the telescope to one of over 30,000
objects in the database. |
What
is Train-N-Track?
The Train-N-Track (TNT)
system is a basic alt-az motor drive system with adjustable or trainable
tracking. With alt-azimuth mounts, the motor speeds will vary
greatly depending on what area of the sky you are viewing. In some
situations, the altitude motor will run very fast and the azimuth motor
will run very slowly. In other areas of the sky, the opposite will
be true. Completely computerized alt-az systems will track
automatically in any part of the sky. The TNT, however, requires
that you adjust the motor speeds for your position.
The adjustment, or training, is very simple. Once you become
familiar with the process it can be accomplished in about 30 seconds and
tracking will continue for 10 minutes or more without noticeable
drifting. At that point you will need to do another simple
training adjustment. Quick slewing can be accomplished, without
adjusting the tracking speed, by simply pressing one key. This
feature allows for re-centering an object without changing the carefully
adjusted tracking speed. Manual movement is possible at any time,
in both altitude and azimuth, without releasing any clutches.

What is an
Alt-Az Mount?
The Meade
LightBridge Dobsonian telescope includes an altitude-azimuth mount.
Altitude-azimuth is sometimes abbreviated as alt-azimuth or just
alt-az. An alt-az mount moves in altitude (up and down) on a
horizontal axis and in azimuth (left and right) on a vertical axis
like a gun turret on a tank. By comparison, an equatorial
mount is essentially an alt-az mount that is tilted to match your
latitude, allowing a telescope to track the stars with the
addition of a simple clock drive. Both types of mounts have
their advantages. Which one is best for a particular
situation depends mostly on how one intends to use the telescope. |
What is a
Transport Storage Kit?
A transport kit supplies
accessories for transporting and using your Alt-Azimuth telescope more easily and
effectively. The kit for the Meade LightBridge includes a bracket for
storing the truss rods and brackets for securing the nose assembly to the
mirror tub, both intended to ease the job of transporting the scope.
Mirror tub counterweights are included for counterbalancing equipment placed
on the nose assembly (on a scope that is already nose heavy without extra
equipment). |
Customer
Comments
"I'm very happy with my TNT and we can
do some good photography with this system. Moon and planets are very
easy targets and some bright objects like M45 too. I expect a
productive winter with my new JMI TNT" (L. C.) |

Frequently Asked Questions
(FAQ)
|
| Q. |
Can I
use the Train-N-Track for Astrophotography? |
| A. |
The TNT is not
designed for astrophotography or for long-term tracking. Rather, it
is designed for easy viewing without having to constantly move the scope
to keep up with the rotation of the earth. |
| |
|
| Q. |
Why
can't the Train-N-Track continue to track all night? |
| A. |
With an
altitude-azimuth (alt-az) mount (see definition of Alt-Az
Mount above) the speed of movement in altitude and azimuth varies throughout
the entire movement of an object across the sky. With the TNT, you
are the one who varies the speed. The Train-N-Track system is
designed to be an affordable alternative to more expensive computerized
tracking systems, which calculate the exact speeds needed in all parts of
the sky. TNT continues in the tradition of the Dobsonian telescope
which was designed to be the most affordable way to get a large-aperture
telescope. |
| |
|
| Q. |
Is the
Train-N-Track compatible with your other products for the LightBridge? |
| A. |
Yes, the TNT is
compatible with our MAX computers, encoders and hardware as well as our
Wheeley Bars. That is, they do not mechanically interfere with one
another. The TNT does not interface with any other products. |
| |
|
| Q. |
How easy
is it to separate and reassemble the scope and rocker box with
Train-N-Track installed? |
| A. |
Technically, the
scope can be lifted off of the rocker box without doing anything to the
TNT. However, we recommend that you remove the thumb nut on the
tangent arm and separate the tangent arm from the bearing and lead
screw. This can be accomplished very easily and quickly. Reassembly is just as quick and easy. |
