Observers in the Northern Hemisphere
N-7 a) Determine the rough longitude of your observing site (example: Munich is 12º E). Now determine
the longitude of the time meridian according to your local time. For the central European time,
this is 15º E (do not use daylight savings time). Calculate the difference between both longitudes;
in our example with Munich, it is 3º.
N-7 b) Now set the secondary scale at your month ring (E 20 10...) to this difference. If your observing
site is east of the time meridian, turn to “E”, if it is west of the meridian, turn to “W”. This setting
has only to be changed when the observing site changes by more than 2-3º.
N-7 c) Loosen the RA setting circle locking screw, turn the setting circle to “0” and tighten the screw
again. In normal operation, this screw should be loose!
N-7 d) Now loosen the RA lock and turn the RA axis until the actual date at the month match with the
local time.
N-7 e) Now adjust the mount using the azimuth and latitude knobs until Polaris fits into the small
circle between 40’ and 60’.
N-7 f) Tighten the RA wedging again and set the telescope to its polar home position.
