Then the display will read,
SET FORK
TO ZERO
This is your cue to rotate the telescope in azimuth until the two stickers on the drive base line up. Then press ENTER.
Next the display will read,
TUBE TO
DOWNSTOP
Now move the telescope tube to the downstop position (pointing down). Press ENTER. The display places you into the
SKY align menu. The display will look like this,
S
KY
ACHERNAR (this will show the catalog object last displayed in the CATALOG menu)
Use the UP/DOWN buttons to scroll through the different ALIGN menu settings (SKY, EARTH, ETC...). Press ENTER
when you decide which alignment method you wish to use. The display will now read,
SKY
A
CHERNAR
with the “A” blinking. You can use the UP/DOWN buttons to scroll to different alignment objects until you have reached
the desired object. Center the telescope on the object and press ENTER. You have just aligned to your first alignment
star. Align the telescope to another star to complete the alignment procedure (an example is given in Chapter 8).
Menu GO TO
This menu tells the telescope to go to the last object displayed in the Catalog Menu. GO TO has three sub menus. Use
the UP or DOWN arrows to scroll to the different sub menus. Here is an explanation of each.
AUTO: Press ENTER here to have the telescope automatically slew to the last object accessed in the Catalog
menu.
MANUAL: Press ENTER here and the display will tell you how far and in what direction the telescope should move
to center the object. Press ENTER again and the information about the object will scroll across the
screen. If you press ENTER while the screen is scrolling, the telescope will slew to the object.
You can also move the telescope by hand to the object. The guide arrows that tell you how far away
you are from the object will guide you to the object.
RELATIVE: This GO TO feature is an even more precise way of finding non-stellar objects. This option is to ensure
that an object is in the field of view of a CCD chip or a medium power eyepiece. When you press
ENTER from this setting, the computer searches through a database of stars to find the brightest star
within 5º of the faint object. The display will prompt you to center the object. After you have centered
the object, using the Diamond Buttons, press ENTER. The telescope will slew to the original object
sought.
Menu CATALOG
This menu is very extensive. You may scroll through the list of catalogs with the UP and DOWN buttons; pressing
ENTER selects a particular catalog for you to scan. Catalogs can be accessed in two ways. You may scroll through the
items or you may input a particular object. Once an object is selected, press ENTER to get a description of type, size,
magnitude, and chart number. Press ENTER twice and the Ultima 2000's built-in high speed motor drive system will
locate the object for you, typically in 10 seconds or less.
The CATALOG menu contains the following: a Star Catalog (ST) which is unique to the Ultima 2000, the Messier
Catalog (M), the Revised New General Catalog (RNGC), Non-Stellar Catalog (NS), portions of the Index Catalog (IC),
portions of the European Southern Observatory (ESO) Catalog, portions of the Uppsala General Catalog (UGC), a user
