Is it I. S. O… or ISO… read all about it on this months Sky & Telescope Blog.
I’ll be attending Daystar’s annual Solarfest star party October 4-7. I will be giving a presentation about @focus3, a new autofocusing technology I developed at Software Bisque. Unlike most “star based” astronomy focusing techniques @focus3 can focus on the sun (and moon, planets, etc.). It’s great for “lucky imaging”, and will achieve good focus even when seeing is not so great; giving confidence that you are at optimum focus even in the case of significant atmospheric turbulence.
