final focusing for astrophotographic framing by
slightly loosening the focuser attachment collar
(turning it counterclockwise), then rotating the focuser
to the desired position, then retightening the collar.
Use of Optional Accessories
Your telescope does not come with eyepieces and
diagonal so as to offer the greatest flexibility in
configuring it to your needs.
The 2” compression ring accessory holder accepts 2”
eyepieces, star diagonals, camera adapters, etc.
There are several accessories that come with the RC
OTA. One is a 1.25” compression ring adapter that
slips into the 2” holder. This lets you use optional 1.25”
accessories (eyepiece, star diagonal, camera adapter,
terrestrial image erecting diagonal, CCD/CMOS
camera, etc.)
Also included with the telescope are three
threaded-on extension rings: one 2” long and two 1”
long.
These extension rings are provided to allow multiple
visual or photographic accessories to reach focus,
depending on their backfocus requirements. They are
designed for installation individually or in combination
between the optical tube and the focuser to take up
unneeded backfocus.
If the focuser drawtube is fully extended and you
are still unable to achieve focus you will need to
install one or more extension rings.
(1) First remove the focuser from the optical tube by
rotating the focuser attachment collar
counterclockwise (a RC8 is shown).
The focuser was removed from the scope.
(2) Install one extension ring, here is a 2” long one.
Thread it onto the telescope firmly. You may add
