Description:
M3 was wonderful; I resolved stars to its very core and was impressed by how
well it took magnification. Using a reference from the book The Messier
Objects, by Steve O'Meara, I determined that I was seeing stars down to 16th
magnitude. As I swept the sky nearby this magnificent showpiece, though, I
stumbled upon NGC 5263. This galaxy is nearly 14th magnitude, but obviously
elongated. By itself, it is not too impressive, but it lies a little over 30
arcminutes from M3. Thus, with a shorter-focal length instrument and a wide
field eyepiece, you could view the two at the same time. This pairing reminds
me of M13 and NGC 6207 in Hercules.
