To open up the telescope, you need to open the dome shutters and the mirror
petals in the following way:
Open the dome shutters by holding down the "OPEN" button under "SHUTTERS"
on the JKT control panel until the button is backlit in green.
Open the mirror petals by pressing once the "OPEN" button under "MIRROR
COVERS" on the JKT control panel. The mirror petals are open when this
button is backlit in green.
It is important to note that whenever you open or close the dome shutters,
the mirror petals must be closed first in order to protect the mirror from
any falling debris.
The JKT has a dome seeing problem. To reduce the temperature difference
between the mirror and the surrounding air (one of the causes of bad seeing),
open the door to the roof access and the door to the dome. This will create a
through draft when the dome shutters are open aswell.
