I found this article on cloudy nights
http://www.cloudynights.com/item.php?item_id=2316
and I wondered if anyone has tried to construct one of these? The link to the Cover Your Astro has been dead for a long time and there does not seem to be any copies of the plans floating on the net. Having said that I spent today pricing the matierials for this from sketches I made from the article and one other at
www.esmithonline.com/astronomy/observatory.htm
The cost of 40mm PVC retic pipe and all of the associated 45 degree bends, wheels, T pieces and Poly tarp to cover it comes out at an estimated $350. Not bad really!
Of course if anyone knows of a copy of the original plans that would be nice?
all the best
