Getting Started
The ShortTube 90 comes nearly fully assembled from the factory. The
telescope’s optics have been installed and collimated, so you should
not have to make any adjustments to them. Open the box and inspect
the contents to make sure all of the parts listed above are present.
WARNING: Never look at the sun with your telescope
(or even with just your eyes) without a professionally made
solar filter. Permanent eye damage or blindness could
result. Young children should use this telescope only with
adult supervision.
Avoid using the type of solar filter that screws into an eye-
piece. They are susceptible to cracking under the intense
heat that builds up near the focus point, and could cause
severe retinal damage. Use only the type of solar filter that
covers the front of the telescope. Be sure also to cover the
front of the finder scope with aluminum foil or another
opaque material to prevent physical damage to the internal
components of the scope itself as well as to your eyes.
