Messier 5 or M5 (also designated NGC 5904) is a globular cluster in the constellation Serpens.
M5 was discovered by the German astronomer Gottfried Kirch in 1702 when he was observing a comet. Charles Messier also noted it in 1764, but thought it a nebula without any stars associated with it. William Herschel was the first to resolve individual stars in the cluster in 1791, counting roughly 200.

Messier 14 (also known as M14 or NGC 6402) is a globular cluster in the constellation Ophiuchus. It was discovered by Charles Messier in 1764.
At a distance of about 30,000 light-years, M14 contains several hundred thousand stars. At an apparent magnitude of +7.6 it can be easily observed with binoculars. Medium-sized telescopes will show some hint of the individual stars of which the brightest is of magnitude +14.
The total luminosity of M14 is in the order of 400,000 times that of the Sun corresponding to an absolute magnitude of -9.12. The shape of the cluster is decidedly elongated. M14 is about 100 light-years across.
R = 9 * 400 sec. bin1, G = 9 * 480 sec. bin1, B = 9 * 560 sec. bin1.

Messier 85 (also known as M85 or NGC 4382 or PGC 40515 or ISD 0135852) is a lenticular galaxy, or elliptical galaxy for other authors, in the Coma Berenices constellation. It is 60 million light-years away, and it is estimated to be 125,000 light-years across.
It was discovered by Pierre Méchain in 1781.

NGC5395 also known as Arp84 the Heron Galaxy is approximately 162 million light years away. NGC5394 is an interacting galaxy, believed to have cartwheeled through NGC 5395. This is a rather small galaxy at 2.7 x 1.3 arcmin.
L = 12 * 1800 sec. bin1, R = 10 * 1000 сек. bin2, G = 10 * 1100 сек. bin2, B = 10 * 1200 сек. bin2, Ha = 12 * 1800 сек. bin2.
