USEFUL AUTOSTAR PROCEDURES

Before trying out the examples in this section, familiarize yourself with the basic oper- ations of Autostar described earlier in this manual. The following examples assume that you have a basic knowledge of Autostar and understand how to scroll to a desired menu or menu option, and how to enter numbers and text. It also assumes that you have initialized and aligned your telescope.

Adding Observing Sites

If you plan to observe using Autostar at different geographic locations, you can store up to six observation sites in Autostar's memory to help simplify your telescope setup. Perform these procedures using the Site options (Add, Select, Delete, Edit) of the Setup menu.

To Add a Site to the user-defined site list:

In this example, you will choose a city and add it to the database list. You will then select the site to enable it.

1.Navigate to the "Setup: Site" menu. Press ENTER,

2.Scroll through the options until "Site: Add" displays. Press ENTER.

3.Scroll through the list of countries/states. Press ENTER when the country/state you wish to add displays.

4.Scroll through the list of cities. Press ENTER when the city you wish to add dis- plays. The Site is now added to the database. You may add 5 sites using this method (the sixth site is the site you added during the manual initialization process).

5.To choose a site, navigate to "Setup: Select." Press ENTER. Scroll through the list of sites. When the desired site displays, press ENTER.

To Edit a Site

In this procedure, you will enter a location that is not available in the Autostar data- base by editing data of a nearby site. You will edit the location's name, latitude. lon- gitude and the time zone shift. You will then select the site to enable it.

You will need to know the latitude and longitude of your location to perform this pro- cedure.

1.Using the Add option, choose a site on the list that is closest to your observing site and press ENTER so that the site is added to your observing sites list. Choosing a site already on the list (as opposed to using the "Custom" feature) makes it easier to edit, as the "Time Zone" value may not need to be changed.

2.Scroll to "Site: Edit" and press ENTER. "Edit: Name" displays. Press ENTER.

3.The name of the site you have just entered to your list displays; if it does not, scroll to the site.

4.Using the Arrow keys, change the name of the site so that it now reads the name of your observing location. Press ENTER. "Edit: Name" displays again.

5.Press the Scroll Down key and "Edit: Latitude" displays. Press ENTER.

6.Using the Number Keys, enter the latitude of your observing site and then press ENTER. "Edit: Latitude" displays again.

7.Press the Scroll Down key and "Edit: Longitude" displays. Press ENTER.

8.Using the Number Keys, enter the longitude of your observing site and then press ENTER. "Edit: Longitude" displays again.

9.Press the Scroll Down key and "Edit: Time Zone" displays. Press ENTER. (If the site you chose from the list in step 1 has the same Time Zone as the site you are editing, just press ENTER again to go on to the next step.) "Time Zone" refers to the Greenwich Time Zone shift. Users West of Greenwich, use "-" hours (one hour per time zone) and users East of Greenwich use "+" hours. For the United States, look up the shift in TABLE 1, at the left.

10.After entering the shift, press ENTER. "Edit Time Zone" displays.

LXD75 specifications

The Meade LXD75 series represents a remarkable range of telescopes designed for both amateur astronomers and advanced users seeking high-quality performance at an affordable price. Known for its robust construction and innovative technology, the LXD75 aims to provide a user-friendly experience while catering to the demands of stargazers looking for sophistication in their equipment.

One of the main features of the LXD75 is its advanced German equatorial mount, which provides exceptional stability and tracking accuracy. This mount is equipped with dual-axis servo motors facilitating smooth movements, making it easy to locate and follow celestial objects. The LXD75 also includes a built-in autostar system featuring a database of over 30,000 celestial objects, allowing users to effortlessly navigate the night sky with a push of a button.

The LXD75 series includes several models, each with different optical configurations to suit the preferences of various users. The telescopes come with either an achromatic refractor or Schmidt-Cassegrain optical design, providing clear and bright images. The Schmidt-Cassegrain models offer a compact design with a fast focal ratio, making them excellent for both astrophotography and visual observation.

In terms of build, the Meade LXD75 features high-quality optics with multi-coated lenses, reducing glare and enhancing light transmission. This results in sharper and brighter images, making it easier to observe delicate details on planets, the moon, and deep-sky objects. The telescope tubes are crafted from durable materials, ensuring longevity and resilience against the elements.

Another characteristic worth noting is the ease of setup and operation. The LXD75 mount comes equipped with adjustable legs and can be easily assembled, requiring minimal tools. The intuitive control system also features a user-friendly interface, allowing both novices and experienced astronomers to operate the telescope with confidence.

For astrophotography enthusiasts, the LXD75 provides excellent support, with a wide range of accessories available to enhance imaging capabilities. The mount can accommodate various cameras, providing flexibility for capturing stunning astronomical photographs.

In summary, the Meade LXD75 series delivers a robust combination of features, technologies, and characteristics designed to meet the needs of both amateur and advanced astronomers. With its reliable mount, quality optics, and ease of use, the LXD75 ensures that stargazers can enjoy the wonders of the universe with clarity and precision.
