OPERATING UNDER THE NIGHT SKY

1). Loosen the locking screw on the par-focal ring. Insert an
optical eyepiece into the eyepiece holder through the par-focal
ring, as shown on the right.
2). Slowly move the eyepiece in and out of the eyepiece
holder until the image of the star is the sharpest. Keep the
eyepiece still with one hand, and firmly push the par-focal ring
against the eyepiece holder with one finger, while tightening the
locking screw on the par-focal ring with the other.
3). The par-focal ring should be firmly attached to the eyepiece.
You may remove the eyepiece from the guide scope now.
ALIGN SYNGUIDER WITH MOUNT
Follow these steps to align the orientation of the autoguider with the moving direction of the two
axes of the equatorial mount:
1). Turn on the crosshair on the LCD screen using the CROSS menu.
2). Adjust the autoguider so that when the equatorial mount is slowly slewing in RA axis the star
image moves parallel to either the horizontal or the vertical line. Instead of using the hand control
of the mount, you may also use the LEFT/RIGHT direction buttons on the SynGuider hand pad to
control the RA axis of the mount.
Attach the 1.25” extention barrel to the eyepiece if the eyepiece is too short to reach focus.
Remember or mark the position of the SynGuider on the guide scope so you won’t
have to perform the autoguider alignment again.
