Never use a telescope or spotting scope to look at the Sun! Observing the Sun, even for the shortest fraction of a second, will cause irreversible damage to your eye as well as physical damage to the telescope or spotting scope itself. To utilize all the features of the telescope, it is necessary to enter some information into the telescope's computer memory, and learn the menu structure of the Keypad hand controller, described later in this manual. As advanced as LX electronics are, the telescope is very straightforward to operate even if you have no experience whatsoever in using a personal computer.

Since the GPS uses Universal Time, and the keypad starts from local time, there is the potential for timing issues that affect precise calculation of the meridian overhead hour angle and the horizons. While these issues will not affect normal go to operation during a night of observing, they can affect syncs done very close to the meridian, and they will affect park position calculations adversely.
Either of these situations can result in the scope being driven into the mount, so it is important that you follow these instructions. For example, for those of us in the US who might be setting up in the evening, UT may already be into "tomorrow," so tomorrow's date could be the correct entry.
Likewise, an Australian setting up his or her keypad in the morning might need to remember that it is still "yesterday" in UT. You can still have locations entered into the keypad, for quick setup at home without using StarGPS, but your time zone for ALL of your entered locations in the keypad must be set to "00" since the entered local time is UT. You will also need to remember that the keypad will now only show UT as the local time.
This should not really pose a problem for astronomers, since we are quite used to converting local time to UT and vice versa. Accurate local time is not necessary in the keypad as long as the keypad can correctly calculate UT, which it does with StarGPS. This means that StarGPS will be initializing your mount, not the keypad. You should be aware that there are additional parts of the initialization sequence that StarGPS cannot perform.
Fortunately, the keypad supplies these parameters even in the External Startup Mode. These parameters include the tracking, guiding and slew rates; the backlash compensation settings for both RA and Dec; reticle brightness and focus speed; and the PEM state. Also, if you are not using StarGPS, you can still proceed through the start-up by pressing the menu button as instructed on the keypad's display, and then proceeding to enter a location number and resuming from park or polar aligning.
You can certainly use your favorite software, just like you normally would. You can change individual parameters that are part of the initialization, like backlash compensation or tracking rate, but DO NOT send time and location data from the computer, and do not do a full initialization. Doing so will overwrite the StarGPS data and may cause the same timing issues that were mentioned above.
It also spoils the whole point of having a StarGPS in the first place. NOTE: You can disconnect the AA power cell at any time following step 9 but you should leave it connected for 20 minutes during the first use.
A single Alkaline AA can supply over 4 hours of continuous power and should last several months unless you forget to unplug it. For maximum battery life and cold weather operation we recommend using an Energizer AA Lithium battery.
To begin with you need to configure the handset to look for a GPS. This is a one-time operation but will need to be repeated if you ever turn on the telescope without the GPS connected Celestron designed it to work this way. NOTE : The local time displayed by the handset is based on the time zone and daylight saving settings. The mount will operate correctly regardless of these settings because all calculations are based on UTC.
Local time is only used for display purposes and for manually inputting time. If you would like the correct local time please be sure that the handset time zone and daylight savings are correct. Please contact us for details. This cable is still available by special order but has been replaced by the GPS-Celestron cable see above. If your HC version is 5. Gemini Level 3 and 4 have the ability to detect a GPS receiver and don't require a power cycle, so we recommend upgrading your Gemini software.
Using the incorrect cable will cause damage to your mount. Meade has corrected the AUX port on newer LX65 mounts as indicated by a white sticker on the battery compartment, see below. The following original Meade versions have a bug in at least one LX command such as "set latitude" or "set date": Autostar 27, 30, 35, 40, 41, 42 , Autostar EP all versions , Audiostar A4S1 and all versions prior to A3S4. If your handset displays any of these version numbers eg.
This can be used to replace the built-in GPS in any of the above models and is useful in cases where the internal GPS is not operating properly. For example, an external GPS-NX02 can be mounted outside an observatory dome and connected via a PS2 keyboard extension cable of up to 50 ft 15m. A StarBook controller with firmware version 1. Before using the adapter for the first time please be sure to charge it as follows:. This procedure will not work with a Synta handset, eg. Run redirect.
Select the Telescope COM port and the same baud rate as above. Turn on the telescope. Press "Connect" to establish the connection between the telescope and GPS. Press "Exit" to disconnect and exit from redirect. GPS results are displayed but not saved. This occurs if you have updated the handset using the free trial version of StarPatch. Turn the telescope off. Check the GPS cable connections and try again.
This problem indicates a faulty GPS receiver or connecting cable assuming that the telescope power supply is working. This problem indicates a faulty connecting cable. This indicates that the GPS is unable to get a satellite location fix. This can happen indoors and can also occur outdoors if you do not have a fairly open view of the sky e. Try leaving the GPS turned on for at least twenty minutes or move to a better location.
You must complete steps 4a thru 4c quickly or the GPS will finish setting the telescope before you skip past the date, time and daylight savings prompts. In this case the GPS results get overridden by the default date and time.
Meade handset display goes blank when the GPS blinks once every two seconds. Press the "0" key to turn the display back on any key will do but "0" is the safest. This happens because the handset automatically turns the display OFF if the keypad is not used for 10 minutes. When the GPS sets the time to anything more than 10 minutes ahead, the handset mistakenly thinks that the keypad has not been used so it turns the display OFF - a minor annoyance. Meade Autostar latitude is not being set.
This problem is due to a bug in Meade software versions 27 and The software version is displayed by the Autostar just after you turn on the power. Meade Autostar alignment fails motor stops or extended slewing. This problem is due to a bug in Meade software versions 35, 40, 41 and This problem is indicated when the GPS LED displays a short on-blink once every second but never transitions to a short on-blink every two seconds.
The problem occurs with handset firmware versions 5. The problem can be corrected by returning the GPS to us for a firmware update - contact us for details. This section describes how to use StarGPS and its components. The Autostar has one serial port which allows it to be connected to a PC for software updates. Follow these steps to update your Autostar:. NOTE: If your handset already had a recent version of software installed prior to using StarPatch, you may not need to reset, re-calibrate and re-train.
In this case you might want to try out the telescope and skip those steps if everything works. Get Updates Connects to the StarGPS web site and lists the latest patch and ROM files that are available based on the current language and handset type. Determines which files you need if any and downloads them.
The file is named according to the patch version number and is placed in the StarPatch folder see installation notes. Prints the current patch file documentation to StarPatchFile. Additional handset registration keys can be entered here if you need to install the GPS Setup patch to a second or third Autostar. COM port Allows you to select which COM port the handset is connected to otherwise this will automatically be determined when you use the "Update Handset" button.
SmartLoad Allows you to enable or disable the SmartLoad feature default is enabled. SmartLoad can achieve faster updates by just sending data that has changed since the previous update. You can disable SmartLoad if you want to force a complete update.
The distribution files include:. The filenames indicate the handset type and software version as in:. If you need older patch or ROM files you can find them here:. These steps assume that you have already used StarPatch to update the handset software so that GPS data will be recognized. At this point you would normally see the "Enter Date:" prompt. This message will appear for 3 seconds and then revert to the "Enter Date:" prompt if there is no GPS connected. This step is not required but is recommended it looks better.
It describes how to setup a "GPS Site" name rather than using a fixed "city name". For example, if the you had previously chosen "Seattle" as the current site then the GPS Setup patch would update the latitude and longitude of "Seattle".
This is probably fine since you are likely to do most of your observing in that area. However, you might want to change the site name to something more generic like "GPS Site". You can do this as follows:. The handset converts UTC to local time by looking at the time zone offset for the current site and the DST daylight savings time setting.
The conversion formula is:. For example, if you selected "Seattle" as the current site then the handset would set the time zone offset to
