Words from a recent mirror customer:
"I've had the mirror out for a few nights now, and all I can say is WOW! Last night was the first really clear night since I installed the mirror (we've been getting some early evening fog-- marine layer-- the last week). After a proper cool down the view of Mars was more than I could have hoped for! I'm sure my wife heard the audible gasp from the backyard. Until now I've never considered doing any sketching of Mars. But there's so much detail now, I owe it to myself. I can't wait for Jupiter & Saturn (at a reasonable hour). Plus, It splits the Double-Double in Lyra at the lowest power I've ever seen. Thanks again for all your help.
