Cover your astro:
I like the design. The crossbar across the opening will probably annoy me. Maybe I can contruct it without the crossbar???
I could always just construct panels. It may be simpler. Here is an example:
Any links, suggestions, or more pictures will be very helpful. I just want something transportable that I can take to my dark sky site to block wind, dew, and ground light.

The crossbar to maintain an opening is a pain due to its height, but you have to somehow link the two ends of the panel chain together for stability. Those panels are equally adept at blocking light and catching the wind, although if you could somehow guy them to the ground that would eliminate the need for attachment.

See "Folding Observatory by Ron Ravneberg", its on the last page of "photo albums"; 10 detailed photos, a nice panel setup.
Sorry, I can't seem to post a link.

Why not buy something like this? It's so cheap you can hardly save any money building it yourself I guess..
I've been looking for something like this for use when I have my scope set up for a week or two at a dark site. I was looking for a place to buy one in the US and discovered that I had a brand new one, from our camping days, sitting in the hall closet!
Thanks for a great idea.

Pannels are made of wood with black plastic 6 mil poly available at the home depot. Sections consist of two pannels connected with hinges with the pins removed. I replaced the pins with bent 4 inch nails. Price for the 6 pannels is less than 100 bucks.They are very lightweight and do the job blocking unwanted light pollution. Dimensions are 3 x 6 for the small pannels and 3 x 7 for the center one.Pannels are lightweigt and can be folded for storage.
