Shooting Mercury
From: Gary LaPook

I did something tonight that I never did before, I took a shot of Mercury as it in conjunction with Jupiter and Venus just after sunset. Now I have to figure out how to work the sight. I figure that I can get the right ascension, convert it to degrees and minutes and then convert it to SHA by subtraction from 360 degrees and then work the sight like a normal star sight. So, does anybody know the right ascension of Mercury at 03:38:50 Z, May 26, 2013?
