Single-speed Focuser Adjustment
To set the single-speed AR80S focuser to a desired setting
you will need to adjust the tension using the single thumb-
screw that can be found under the focuser.
Simply turn the thumb-screw
A one way to increase the
Crayford focuser’s holding capacity, turn the thumb screw
the other way to reduce the holding capacity of the
focuser.
Increasing the pressure will enable the focuser to hold more weight but the focuser
will become slightly less sensitive. As such it is important not to unnecessarily over-
tighten the thumb-screw.
An Imaging Setup
The Opticstar short tube refractors are ideal for deep sky imaging. They can be used
as part of an imaging system as illustrated below.
