Description

Another very bright small planetary nebula. Mice discussion on Cloudy Nights:

Their information:

NGC 6210 is a planetary nebula found in the constellation Hercules.

It is located between 4000 and 6500 AL of the earth.

It is difficult to exactly locate a planetary nebula.The problem is that it is impossible to tell the difference between an NP which is 4000 AL of another which is 8000AL but which is 2x more luminous !

The Turtle is a very bright NP (mg area: 9) but small, the heart is almost 18 ''. It takes tight sampling to differentiate the details between them.

For something that actually looks like a turtle, see Hubble:
