GoTo Hand Controller Operation

This section provides a guide for initial setup and alignment of the SkyView Pro mount with the GoTo hand controller.

Initial Setup

1.Perform the polar alignment using the procedure previ- ously outlined in Section 6 of the instruction manual that came with your SkyView Pro mount. A rough polar align- ment will suffice, but an accurate polar alignment using the polar axis finder scope will increase tracking accuracy (and pointing accuracy for one-star alignments).

2.Rotate the telescope tube about the mount’s declination axis so the tube is parallel with the mount’s R.A. axis (and the front of the tube is pointed to the sky, not the ground). Rotate the mount’s R.A. axis so the counterweight shaft is pointed straight down. This will be called the “home” posi- tion of the mount (Figure 15b).

Note: Once the mount is initially set to its “home” position, the mount should not be moved manually. Otherwise, the GoTo hand controller will lose track of the mount’s position, and the alignment procedure will need to be performed again. Keep both the R.A. and Dec. lock levers engaged.

3.Turn on the power switch on the motor control box.

4.The initial screen displayed on the hand controller is the version screen. Press ENTER to proceed.

5.The hand controller’s LCD screen will show a safe solar viewing warning message. Press the ESC button to con- tinue.

Note: The GoTo hand controller’s LCD backlighting will become dim and the illuminated buttons will turn off if left idle for 30 seconds. Pressing any button will re-illuminate the hand controller.

6.Enter your observing site’s longitude and latitude coordi- nates. First enter the longitude coordinate and hemisphere, followed by the latitude coordinate and hemisphere. Use the numerical keypad to enter the digits, and use the left and right directional buttons to move to the next digit. Use the scroll buttons to choose W or E (for longitude) and N

or S (for latitude). If you do not know the longitude and latitude coordinates of your viewing location, consult an atlas or geographical map of your area. Press ENTER to confirm your coordinates.

Note: Longitude and latitude coordinates must be entered in degrees and arcminutes. If your map or atlas gives coor- dinates in decimal values (i.e. latitude = 36.95 N) you must convert into degrees and arcminutes (i.e. latitude 36.95 N = latitude 36°57’ N).

Note: If a mistake is entered into the hand controller during the initial setup procedure, press the ESC button to go back to the previous screen.

7.Enter the time zone in which you are observing in hours (see Appendix D), using the scroll buttons (+ for east of Prime Meridian, - for west of Prime Meridian) and numeric keypad. Use the left and right directional buttons to move to the next digit. Press ENTER to confirm your choice.

8.Enter the date in mm/dd/yyyy format using the numeric keypad. Use the left and right directional buttons to move to the next digit. Press ENTER to confirm your choice.
