Preparing the telescope for an observation
A
. Upon delivery, and when not used, the
telescope and its accessories are inside the
aluminum padded case. Unpack the
instrument…
B
. The instrument is ready to be placed on
the mount, via the EQ5 (Vixen style)
dovetail bar. Please refer to your mount
manual for proper and secure installation.
C
. The 9x50 erect-image finder scope is a
small fixed magnification scope mounted
on the optical tube. When it is correctly
aligned with the telescope, objects can be
quickly located and brought into the field
of telescope (see also "
Aligning the finder
scope
" chapter, on next page)
To install the finder scope on the telescope
insert the positive dovetail of the finder
scope support inside the negative dovetail
mounted on the focuser, as shown in
picture.
Cooling the telescope
Telescopes require time to cool down to outside air temperature. This may take longer if there is a big
difference between the temperature of the telescope and the outside air. This minimizes heat wave
distortion inside telescope tube (tube currents). Your telescope would require at least 15 minutes
cooling off to outside conditions. Tip: use this time for planning your session and mount accessories.
