Figure 25. Collimating the optics. (a) When the mirrors are properly aligned, the view down the focuser drawtube should look like this. (b) With the collimation cap in place, if the optics are out of alignment, the view might look something like this.

(c)Here, the secondary mirror is centered under the focuser, but it needs to be adjusted (tilted) so that the entire primary mirror is visible. (d) The secondary mirror is correctly aligned, but the primary mirror still needs adjustment. When the primary mirror is correctly aligned, the “dot” will be centered, as in (e).

Setup Functions

The Setup functions allow you to change any system variable or information regarding location, time, date, and alignment configurations. To access the Setup Functions, either press the SETUP button on the hand controller or browse to SETUP on the Choose Menu screen using the mode and scroll keys. The different types of functions available to you are listed below, along with their respective purposes.

Date: Allows you to change the date entered at the initial setup.

Time: Allows you to change the current time.

Observ. site: Allows you to change the current location set- ting.

Daylight Saving: Allows you to change the Daylight Saving option.

Alignment: Allows you to re-perform the star alignment.

Alignment Stars: Allows you to choose how alignment stars are displayed.

Auto Select: When selected the hand controller will filter out stars not available for selection.

Sort By: Generates a list of alignment stars sorted alpha- betically or by magnitude.

Backlash: This function allows you to insert a value for each axis to compensate for slewing backlash experienced on that axis. Backlash is a delay in motorized motion of the mount due to slack between gears. Backlash is experienced when the slewing direction is reversed on one or both axes of motion. For improved pointing accuracy, it is important that the back- lash value is set to be equal or greater than the actual amount of backlash between the gears. The default setting is 0° 00’ 00" (degree, arcminute, arcsecond). Use the numeric keys to set the values and press the RIGHT directional key to pro- ceed to the next digit. First set the value for R.A. backlash, then press ENTER to set the value for DEC.

Note: Backlash compensation is only active for comput- erized slewing, not for manual slewing with the direction- al buttons.

Tracking:

•Sidereal Rate: Activates tracking at sidereal rate. This is the default tracking rate.

•Lunar Rate: Activates tracking at lunar rate.

•Solar Rate: Activates tracking at solar rate.

•Stop Tracking: Stops the tracking motors.

Auto Tracking: Allows the telescope to automatically track a celestial object without star alignment. The hand controller will display the coordinates of the direction in which the telescope
