If you don't already have it this site is very useful. A search by name of object or co-ordinates will give you a DSS image of the area.

The NED site that Ron refers to is listed below below and can be searched by a host of criteria.

Yup Roger is right, it wasn't that long ago that NGC5189 in Musca was classed as a galaxy and is now classed as a planetary nebula - The Spiral Planetary in Musca
Did you end up finding a Sky6 Pro?
