are above the horizon
select and confirm the first calibration star with ENTER

2.

center the star in the eyepiece (the finderscope is often not very helpful, since it is most of the

3.

time not well aligned with tube)
confirm with ENTER

4.

press ALIGN → afterwards the telescope suggests the second alignment star

5.

select and confirm the second calibration star with ENTER

6.

center also this star in the eyepiece (in case it is not possible to find this star, one can select a

7.

new star by pressing UNDO)
confirm with ENTER

8.

press ALIGN → subsequently, the alignment can be improved with additional stars (3 are

9.

recommended, 6 are possible)
press UNDO to complete the alignment

10.

Hibernation

The hibernation mode offers the possibility to use the telescope several nights in a row, while
switching off the power supply during the day. It ensures that the alignment will be conserved.
However during hibernation, it is not allowed to move the telescope at all. The following steps are
necessary to put the telescope into hibernation:

press the MENU button

1.

select HILBERNATE from the UTILITES menu

2.

move the telescope to the desired park position

3.

switch off the telescope

4.

disconnect the power supply and arrange for weatherproof cover (Important: do not move the

5.

telescope anymore!)

Wake up:

reconnect the power supply

1.

switch on the telescope

2.

confirm Wake up with ENTER

3.

confirm the time and the location

4.

The telescope is ready for the next observation!

5.
