Very nice. What is your setup? Experimenting now with iPhone 5c and my Lunt 60 B1200 CaK on a modified Eon 72, but clouds messed we up this afternoon. Have had fair results with Canon SX120 on manual mode at about 1/30-1/4 second exposures.

How do you get best focus? My old eyes seen nothing through the eyepiece, so all focusing must be done on camera screen.
