Operation Of The Eq-1 And Eq-2 Mount - Omegon EQ-1 Mode D'emploi

3.4 Operation of the EQ-1 and EQ-2 mount

Abb. c
The EQ-1 and EQ-2 mount sits on the tripod and is fixed in place from underneath by means of a large
thumbscrew. The mount can be moved around two different axes, in each case in two directions. The RA axis and
the DEC axis can be moved in each direction by means of the two flexible slow motion controls once the locking
screws have been tightened. This manual fine positioning allows the accurate centring of celestial objects as
well as tracking them, i.e. compensating for the Earth's rotation. Once the mount has been accurately aligned,
this compensation only has to be done in the RA axis.
