nearly-new GTs available

Posted By Roland Christen

I'm concentrating on making a large number of them, so they do not have the scarcity of some of the other scopes in the past. The list for these is getting shorter.

2010 Camaro SS Ahhh the good ole NEW days

Posted By Roland Christen

Nice looking car, however, the new Challenger SRT8 has it all over the Camaro in the looks department. I can't wait to "challenge" either one of them with my Roush Mustango wink

Extreme stretching will bring out gradient in the image. Some water vapor in the air will cause brightening around bright stars. You've seen this on nights when the Moon is full and surrounded by bright sky background that fades away with distance from the Moon.
