Just an update.
My homemade IOTA is about a 5 out of 10. It probably doubles the clarity/resolution at 50 feet. Almost useful.
I have not heard from Bob and Chuck saI'd he is looking into (FRAUD ALERT) and that was the last I heard.
My scope has not fogged. I am hoping oxygen and moisture did not replace the noble gas in it, there is just less. I may send it in after Christmas break in case I get the chance to get some shooting time in then.
