photographer to index focus position to within 0.0005” by means of a digital indicator. Mounting
points are provided on top of the focuser body and end of the draw tube for easy installation of the
various Digital Indicator Kits. Using the Digital Indicator provides a convenient way of finding best
focus, returning to it, or checking that it hasn’t changed.
Choose either the 10 Micron (0.0004") Indicator Kit (LMK-2404) or the 1 micron Indicator Kit (LMF-2405)
depending on the accuracy desired. Both indicators have 0.5" motion ranges and accept an RS-232
output cable for displaying readout on computer. The 10 foot long RS-232 Output Cable (RSC-2320)
permits remote indicator readout on computer screen via down-loadable software from the Tele Vue
website (www.TeleVue.com). The cable also provides power to the indicator.

6.0 Caring for your 102iis
The Tele Vue-102iis requires no special care. Treat it as you would any fine camera lens. Use the lens cap
when the telescope is being stored or not in use. The captive dew shield provides protection from glare,
helps protect the lens from dust or spray blown in by the wind and minimizes dew formation on the lens.
If dew forms on the lens during cold weather, it is best to use a hair dryer (on the lowest setting) to gently
warm it away. A few specks of dust will have no effect on image quality and may be gently blown off with
a squeeze bulb. Do not use compressed air cans to blow dust off optical surfaces.

Fingerprints, however should be cleaned off. Though the anti-reflection coatings are durable, they are
easily scratched. The simplest cleaning method is to moisten (not soak) a very soft, lint-free tissue, cloth, “Q-
Tip” or surgical cotton with a lens or glass cleaner and gently whisk away the stain. Do not apply any
solutions directly to the glass surfaces. After every cleaning stroke, use a fresh applicator. The fewer strokes
the better! Any residual “film” will not affect visual performance.
Collimation of your Tele Vue-102iis has been locked at the factory. With reasonable care it will remain
aligned. However, rough handling can cause misalignment. WARNING: Do not loosen the button head
screws in the front lens cell as this will cause misalignment. If necessary, contact Tele Vue for re-collimation.
The tube is powder-coated for durability and needs no maintenance. Black anodized surfaces can be
cleaned with Windex. If you have any questions about the care, operation or performance of your Tele Vue-
