I have a couple domes I have built and am looking to sell. they are 22 ft -2V. made of 1-3/8 steel tubing. the steel was outside, so they got rusty & a little pitted, so I sanded, primed and painted them. I will sell each frame for $700. I know with the price of steel you cannot even get the material for that price. I really need an excuse to go to dark skies, so If you want one i will deliver it to DS and show you how to set it up. I can do it alone in less than 2 hours. If interested, contact me & we can discuss it further.
