Adjustment and Use
The Digital Indicator has
0.5" of travel. It is ideal to
set the shaft within the
middle of its travel range.
To do so: achieve a
rough focus with your telescope. Slide the indicator
against the stop until the
shaft has moved approximately half way through its
travel. Use the small Allen
key and tighten the two set
screws on the side of the
Dovetail Channel that contact the indicator Dovetail.
If the indicator needs more
or less adjustment room to
reach the stop, first determine if repositioning the Stop
Bracket will help. For more
adjustment, remove the digital indicator from the channel, loosen the set screws
(see step 4) and slide the
Indicator Dovetail in the necessary direction. Retighten
the set screws.
Turn the micrometer on
and zero it if necessary
Start critically focusing
the image. Take note of the
micrometer reading so you
may return to that position if
further adjustment does not
improve focus.
Details regarding the
use of the indicator can be
found on the instructions included with the unit.
The optional RSC-2320
cable plus TVFocus software
(download available at
www.TeleVue.com) permits
remote viewing of the
indicator's reading.
