The standard Kenko tracker's electronics and mechanical system
does excellent open-loop sidereal tracking. However, for some
situations such as shooting close
to the horizon where refraction effects may affect tracking, the
ability to correct the tracking is important.
The standard Kenko tracker includes a two-button hand control which
allows manual correction of tracking. This cable can be extended by using
common extension cables with 3.5mm 3-conductor stereo connectors.
The Kenko's RA correction input may also be used with an autoguider
using the KD-2 cable adapter (shown at right with autoguider camera)
which allows for the connection
of an autoguider with fully-isolated (e.g. relay) outputs. The adapter input is an
SBIG/Losmandy type (6-pin telephone) connector.
