A seldom imaged open in the Hydra constellation.

The Rosette Nebula (also known as Caldwell 49) 

Located at a distance of 15,800 light-years (4,850 pc), it is the largest globular cluster in the Milky Way at a diameter of roughly 150 light-years.

M3... considered one of the finest northern globular clusters. Taken from light a light polluted sky in Davie FL.

 Under dark skies the Beehive Cluster looks like a nebulous object to the naked eye; thus it has been known since ancient times. 

Both visible with the naked eye, NGC 869 and NGC 884 lie at a distance of 7500 light years.

The Wild Duck Cluster is one of the richest and most compact of the known open clusters, containing about 2900 stars. Its age has been estimated to about 250 million years. Its name derives from the brighter stars forming a triangle which could resemble a flying flock of ducks (or, from other angles, one swimming duck).

The brightest and largest globular cluster in the Milky Way, containing as many as 10 million stars
The globular cluster is found in the constellation Centaurus, in the Southern Hemisphere.
It is 16,000 light-years from earth.
