PRIMARY MIRROR ADJUSTMENTS

 

If the 

secondary mirror 

(fig. 7, #1) and the reflection of the 

primary mirror 

(fig. 7, #2) appear centered within the

 draw tube

 

(fig. 7, #3), but the reflection of your eye and the reflection of the 

secondary mirror 

(fig. 7, #4) appear off center, you will need to 

adjust the 

primary mirror tilt screws 

(fig. 3, #2) of the 

primary 

mirror cell.

 These 

primary tilt screws

 are located behind the 

primary mirror

, at the lower end of the 

main tube. 

To adjust the 

primary mirror tilt screws

 (fig. 3, #2), first turn by 

several turns, the 

primary mirror cell lock knobs

 (fig. 3, #3) 

that are next to each

 primary mirror tilt screw

. The three 

primary mirror cell locking screws

 are slotted head screws 

on the EclipseView 114 models. Then by trial-and-error, turn the 

primary mirror tilt knobs

 (fig. 3, #2) until you develop a feel for 

which way to turn each knob to center the reflection of your eye. 

Once centered, as in 

Figure 5

, turn the 3 

primary mirror cell 

locking screws

 (fig. 3, #3) to re-lock the tilt-angle adjustment.

(114mm Models Only):

NOTE: The EclipseView 82mm telescope does 

not have primary mirror collimation screws and is 

permanently mounted at the factory.
