Declination Axis Assembly (Dec Assembly)
The declination assembly is a permanent component of the Paramount and cannot be removed.
Paramount Serial Number (Serial Number)
The Paramount’s serial number is permanently affixed to the base of the hour angle assembly before
shipment (page 44).
Altitude Scale
The Altitude Scale is a series of tic marks machined into the edge of both altitude wedge plates. On the
Paramount ME, the longer tic marks represent approximately ten-degree increments, the medium tics are
approximately five-degree increments, and the shorter tics are approximately one-degree increments.
The short tic marks on the Paramount MYT and MX altitude scale represent approximately two degrees
in elevation; longer tic marks represent about ten-degree increments.
When the mount’s base is close to level, this scale can be used to set the altitude of the polar axis to plus
or minus fifteen arcminutes or so.
The altitude of the mount’s polar axis can be determined by looking at the intersection of the bottom of
the altitude reference block and the nearest tic mark on the altitude scale (Paramount ME, Figure 37), or
the machined arrow on the base of the Paramount MYT and MX hour angle housing Figure 38.
