Double rainbow
Two weeks ago I got my Baader Herschel wedge. I could not get my 4-inch refractor into focus using my 1.25 eyepieces. I could not turn the focusser inward far enough. Yesterday I visited a fellow observer who is going to shorten my TAL 100RS refractor by two inches. I hope that I can use the Herschel wedge with this "shorter" refractor. I will keep you updated. Just before leaving I shot this image of a beautiful (double) rainbow.
