Hi, Just a bit of a basic math question that i am sure i am over thinking.
I have came across this document for calculating wall height for an observatory, it basically works on a 25 degree angle which i think is a good number, I think going below 25 degrees you end up in too much atmosphere ( any comment on this would be appreciated ) The shed is out in a pretty open area, so not much in the way of tress, houses

My shed is going to be 3m X 3m
Pier dead center and a height of 950 mm
I am just trying to work out with that document link above, if the height ( given as Hscope ) is just the height of the counter balance shaft when it is at horizontal?
If so, my mount is about 360 tall when the counter balance shaft is at horizontal.
So that makes the Hscope height a total of 1310mm
Putting it all together, 25 degrees ( 0.466 ) X 1500 mm ( Centre of shed to wall ) = 699 mm + 1310 (Hscope ) = 2009 mm Height of wall
So in summary, if this Hscope is the height of the counter weight shaft, then my wall height can be at a maximum of 2 meters tall.
Dose all this sound about correct?
Sorry for the long drawn out question here,
But any advice would be appreciated.
Thanks.
