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.
