In my professional life, I have to write requirements first. I found out
that I did also for this project - some time in April this year (2003)
I wrote what I wanted from my telescope hut on the back of an envelope.
Here it is:
My main use of the telescope would be:
House the 16" Cassegrain
Protect telescope and observer from wind
Protect telescope and observer from lights
Allow view to the ecliptic - in the south down to 20 deg to the horizon
Accomodate two people
Allow comfortable (heated?) work when recording videos of planets and other
These requirements result in some technical requirements to the observing
Video observation of planets
Long-exposure CCD photography of comets, possibly of asteroids
Visual observation of everything ('sightseeing').
In the end I decided that I want a hut with 2.8 m x 3.5 m open space -
a little bit more to one side to accomodate a desk for star charts etc.
in the open. Plus a little area which is permanently covered of about 1.5
m x 2.8 m, resulting in a total ground floor area of 2.8 m x 5.0 m. Somehow
I always new I want a hut with a roll-off roof rather than a dome, due
to the easier fabrication.
Walls must be higher than my eyes - use 2 meters as baseline
Height of pier must be 1.2 m. This will result in a height of the center
of the axes of 1.5 m, thus I can reach 20 deg altitude.
Size of open area around telescope should be larger than 2.5 m x 2.5 m
(tested with my 6" refractor which has about the same length as the 16"
Have an enclosed part of the building which accomodates at least a desk
for the computer controlling the video camera and/or CCD camera
