Connection Instructions
( Aligning R.D.F. )
Step-2
Use a 2mm Allen key to loosen
the setscrew on the left side
of the RDF, near the bracket
under the letter "R". Using a
2.5 mm Allen key make
adjustments to the Alt-Az
adjustments (marked R and
UP) until the red dot in the
reticule overlays the same
object as the center of the
eyepiece view.
Step-3
Using a high magnification
eyepiece (short focal length)
repeat this procedure for fine
alignment.
Step-1
Find a distant object in the

Step-1
Take out the finderscope screw from
the drawtube top with a small flat
screwdriver. This is the larger black
screw at the left of the rotation lock
thumbscrew.
We suggest positioning the RDF base
with the thumbscrew facing towards
the left (for clarity purposes it's shown
on the right hand side on these
instructions).

Astronomical Instruments
The alignment of the finder needs to be performed only when necessary. We
recommend aligning during daytime by point telescope and finder at the same
far object.
