Calibrate Motor: If the telescope motors appear to have a problem, use this option to retest the motors before doing a Reset. This option is also used if a Starfinder unit is moved between telescopes to match Starfinder to the telescope.

High Precision: If High Precision is turned on when looking for a faint celestial object (i.e., a nebula or galaxy), Starfinder first slews to a nearby bright star and requests "ENTER to Sync." Center the star in the eyepiece, then press ENTER. At that point the telescope has a high precision alignment to that part of the sky and it then slews to the object that was originally requested.

Targets switches between astronomical targets and terrestrial targets. If "Astronomical" is selected, the telescope tracking motor is activated. If "Terrestrial" is selected, the tracking motor is turned off. See "OBSERVE A STAR USING THE AUTOMATIC TRACKING FEATURE," page 16, for more information.

Site provides access to the following options:

Select: Displays the currently selected observing site and also allows you to select other sites you have entered into a user-defined database (see "Add" below). Use the Scroll keys to cycle through all available sites in this database. Press ENTER when the site you wish to select displays. Use this option when you move to a different geographic location.

NOTE: Only the site that is entered during Initialization (see page 17) will be displayed in this database until other sites are entered with the "Add" option.

Add: Allows you to add new observing sites to the database (up to six sites may be stored). Scroll through the list of Countries/States. Press ENTER when the site you wish to add displays. Then choose the desired city in the same manner.

Delete: Deletes a stored site from the database.

Edit: Edits a selected site, including: the name, latitude, longitude, and time zone. Time zone refers to the Greenwich Mean Time (GMT) time zone shift. Users West of Greenwich, England, use “-” hours, East of Greenwich use “+” hours. For the United States, look up the time zone shift in Table 1.

NOTE: Starfinder compensates for daylight savings time, if selected (see "DAYLIGHT SAVING," page 31).

Owner Info accesses the owner information menu options, including:

Name: A user may enter both his or her first and last names using the Up and Down Arrow keys to cycle through the alphabet. Use the Right and Left Arrow keys to move across the text. Press ENTER when the entry is complete.

Address: Use the Up and Down Arrow keys to enter your street address, city, state, and zip code. Press ENTER when the entry is complete.

Download transfers information from a personal computer or another Starfinder.

NOTE: The Download function requires the optional Cable Set. See the instruction sheet for the optional cable set for more information on how to download.

Statistics provides basic statistical data about Starfinder, including:

Characters Free: Shows how much room is available in user-defined object memory.

Version: Shows the current version of the Starfinder software.

Reset completely resets Starfinder. Starfinder requires initialization again after a Reset before proceeding with observations. See “ INITIALIZING STARFINDER,” page 17. You will also need to perform “TRAINING THE DRIVE,” page 19, after a Reset.

Meade 4504 instruction manual Time Zone Shift

4504 specifications

The Meade 4504 is a notable member of Meade Instruments’ extensive line of telescopes, designed for both beginners and experienced astronomers. This telescope is known for its user-friendly features and impressive optical performance, making it an excellent choice for stargazers keen on exploring the night sky.

One of the key features of the Meade 4504 is its 4.5-inch aperture, a critical factor that determines the amount of light the telescope can gather. This larger aperture allows users to observe fainter celestial objects, from nebulae to distant galaxies, with clarity and detail. The telescope is equipped with a Newtonian reflector design, which utilizes a primary mirror to collect light and a secondary mirror to direct it to the eyepiece. This design effectively eliminates chromatic aberration, offering sharp and crisp images.

The Meade 4504 also boasts a mount that is robust yet user-friendly. It typically comes with an Altazimuth mount, which allows for smooth movement both vertically and horizontally. This makes it easier to track celestial objects as they move across the sky. The mount's stability is crucial during high-magnification viewing, as it minimizes vibrations and provides a steady image.

A standout feature of the Meade 4504 is its ease of assembly and operation. Designed with beginners in mind, it usually includes a straightforward setup guide that allows users to get their telescope ready for use quickly. Additionally, the telescope often comes with a finderscope, which helps in locating objects in the night sky, a crucial tool for novice astronomers still learning to navigate the cosmos.

In terms of accessories, the Meade 4504 often includes a variety of eyepieces, allowing users to switch magnifications for different viewing experiences. These eyepieces enhance the versatility of the telescope, catering to varied interests, whether it's observing planets within our solar system or examining the details of various star clusters.

Overall, the Meade 4504 represents a balance of quality, convenience, and affordability, making it an ideal choice for anyone looking to embark on a journey of astronomical discovery. It effectively brings the universe closer to home, allowing enthusiasts to explore the wonders of space with ease. Whether you are a first-time observer or someone with a passion for celestial exploration, the Meade 4504 offers a remarkable gateway to the night sky.
