- The
Tectron tools have been the most popular collimation tools on the
planet since 1984. They are more responsible for the revolution in
good telescopic images than all the other tools ever made. They are
still available by direct order from Tom Clark, at very reasonable
prices.
-
-
- Sight
Tube...........................................$38.00
- The basic mechanical alignment
tool for Newtonian telescopes. This tool is necessary for placing
the diagonal mirror in the proper place, and aiming the diagonal mirror
at the center of the primary. If you only buy one tool at a time -
this is the one you need first.
..
- Cheshire..............................................$46.00
- Once your diagonal is in
the proper place, you are ready for the Cheshire. This tool is probably
one of the most used tools of the set. It is used for very close collimating
the primary on a Newtonian, either in the daylight or in complete
darkness, for those times when you don't set up till late. Simply
shine your red flashlight into the opening. If you have a refractor,
this is the tool to use.
- ..
- Autocollimator...................................
Included with Full Set of Tools
- This is the final step for
collimating your Newtonian. Don't try to use it without first going
through the proper steps with the Sight Tube and Cheshire. It won't
work! The collimation has to be close to begin with or this tool will
frustrate you because it is so critical. This tool is also for collimating
classical cassegrains. (Not for catadioptrics.)
- .
- The
autocollimator is not available separately, but only when purchased
with the full set of Tectron tools. The cheshire and sight tube will
still be sold separately.

"The
most important tool any technician can use to achieve a
complex task or create a complicated device is to have a
plan. The plan should explain what is to be accomplished
and list the procedures or processes that detail 'how to
do it'. With this principal in mind, the most important
item provided by Tectron is their booklet "Perspectives
on Collimation."
Paul Valleli, S&T March 1988 |
