Inspecting the Optics
A Note About the “Flashlight Test”: If a flashlight or 
other high-intensity light source is pointed down the 
main telescope tube, the view (depending upon the 
observer’s line of sight and the angle of the light) may 
reveal what appears to be scratches, dark or bright 
spots, or just generally uneven coatings, giving the 
appearance of poor quality optics. These effects are 
only seen when a high intensity light is transmitted 
through lenses or reflected off the mirrors, and can be 
seen on any high quality optical system, including giant 
research telescopes.
The optical quality of a telescope cannot be judged by 
the “flashlight test;” the true test of optical quality can 
only be conducted through careful star testing.
Gauging the Movement of
the Telescope
A common complaint of many first-time telescope 
owners is that they cannot see the telescope “move” 
when the motor drive is engaged. If fact, when the 
batteries are installed, the power is on, the telescope 
is moving. However, the movement is at the same 
speed as the hour hand of a 24-hour clock; as such, 
the movement is difficult to discern visually. 
To check the movement of your telescope, look at an 
astronomical object through the telescope’s eyepiece 
with the telescope polar aligned and with the motor 
drive on. If the object remains stationary in the field 
of view, your telescope is operating properly. If not, 
check to ensure that “Astronomical” is selected in the 
“Targets” option of the setup menu. 
Updating Your LS-6 Firmware
Meade is constantly refining and improving the operating 
firmware that controls our computerized telescopes and 
we even add new features and capabilities from time 
to time. Your new LS-6 shipped with the most current 
firmware at the time of manufacture, but there may 
well be a new version available through the AutoStar 
Updated program supplied on the AutoStar Suite DVD 
MAINTENANCE
supplied with your telescope. The Updater goes online 
to the Meade web site and checks to see if there is a 
newer version available and can download it directly 
to the telescope through a user supplied USB cable 
or it can create a bootable Mini SD Card that, when 
inserted into the telescope’s Mini SD Card slot (Pg. 12, 
Fig. 3, 10), will transfer the files to the telescope on 
startup. Please see the AutoStar Suite documentation 
for details on how to perform the update.
Here are the steps to update your firmware:
1. Install AutoStar Suite software and the USB driver
from the DVD included with the telescope.
2. Attached telescope with user supplied USB
cable or insert a mini SD card or micro SD in mini 
holder into a card reader to internet connected 
computer.
3. Turn on the LS-6 and press “MODE” to abort
from the alignment.
4. Run AutoStar Suite
5. Select the “Telescope” menu from the menu bar
near the top of the screen.
6. Select “Product Updates” from the drop
down menu.
7. Click “OK” or “Yes” in the message box to
be sure you have the latest version of the 
Updater software.
8. If you see “Error Box” about searching for COM
Ports and you have your telescope connected 
with a USB cable, click “Yes”. If you are using an 
SD Card, click “No”.
9. Click on “Upgrade AutoStar Software Now”.
10. Open the drop down menu called “Specify Type
of AutoStar...”.
11. Select LS-6.
12. If you want to make an Mini SD Card, check the
SD box.
13. Click “OK” and the firmware will download
and install.
