Meade 8" LS-8 ACF, 8" LS-8 SC, 6" LS-6 SC, 6" LS-6 ACF instruction manual Slew Speeds

Page 21

Arrow Keys: Slew the telescope in a specific direction (up, down, left, and right), at any one of nine different speeds. Speed selection is explained in “SLEW SPEEDS”, below. The following functions are also available with the Arrow keys:

•Moves the telescope – Use the Up and Down Arrow keys to move the telescope vertically up and down. The Left Arrow key rotates the telescope horizontally counterclockwise, while the Right Arrow key rotates it clockwise.

•Data entry – When the scope is prompting for user entered data, use the Up and Down Arrow keys to scroll through the letters of the alphabet and numerical digits. The Down Arrow key starts with the letter “A” and the Up Arrow key starts with the digit “9.” The Left and Right Arrow keys are used to move the blinking cursor left and right across the LCD display.

•Catalog Paging – When the scope is presenting long catalogs of information, cities, celestial objects, stars, etc…, you can move through the list a page (8 items) at a time using the up and down arrow keys.

Number Keys: Each number key on the handbox serves a dual function. When you prompted to enter numerical information, the keys allow you to directly enter digits into the handbox. At all other times, the numeric keys act as shortcuts to frequently accessed places in the menu tree. The keys have the follow effec:t

“1/Speed” – instantly brings up the scope slew speed menu so you can change the slew rate of the telescope

Slew Speeds

LS has nine slew speeds that are directly proportional to the sidereal rate (the rate at which stars appear to drift across the sky) and have been calculated to accomplish specific functions. Pressing a Number key changes the slew speed, which is shown for about two seconds on AutoStar’s display.

To change the speed, press the 1/Speed. Nine available speeds are:

Number Key “1” = 1x

Number Key “2” = 2x

Number Key “3” = 8x

Number Key “4” = 16x

Number Key “5” = 0.25°/sec

Number Key “6” = 0.50°/sec

Number Key “7” = 1.0°/sec

Number Key “8” = 2.0°/sec

Number Key “9” = 4.0°/sec

Speeds “1”,“3”, or “3” Best used for fine centering of an object in the field of view of a higher power eyepiece, such as a 12mm or a 9mm eyepiece.

Speeds “4”, “5”, or “6”: Enables centering an object in the field of a low-to-moderate power eyepiece, such as the standard Super Plössl 26mm.

Speeds “7” or “8”: Best used for rough centering of an object in the Red-Dot Viewfinder.

Speed “9”: Moves the telescope quickly from one point in the sky to another.

“2/Caldwell” – instantly brings up the Caldwell catalog entry menu, so you can access any Caldwell object by its catalog number.

“3/Messier” – instantly brings up the Messier catalog entry menus, so you can access any Messier object by its catalog number.

“4/Focus” – If you have a optional electric focuser attached to your telescope, this key will change the function of the Arrow keys, to move the focuser in and out, rather than to move the telescope.

“5/Planet” – instantly brings up the solar system object selection menu. So you can quickly locate the moon, planets, comets and asteroids.

“6/Stars” – instantly brings up the star catalog selection menu, so you can quickly locate bright stars by name, or select stars by their catalog index numbers.

“7/Volume” – brings up the volume control for the built in speaker in your telescope.

“8/Tours” – instantly brings up the guided tours
