Post by KingNothing13 »


Hi all - I apologize for the lateness of this list, as well as for missing December - things got out of hand, and time has been moving way to fast for my liking lately!

Anyway, here are 4 targets for this month, good luck and "keep looking up!"

All of the text descriptions come from SkySafari.

Some day, maybe I'll get to participate in my own program! :lol:
