NGC6952 was discovered at the Marseilles Observatory by French astronomer Jerome Coggia in 1877. Lewis Swift, independently discovered this same galaxy using the 16" refractor of Warner Observatory 8 years later on September 14th, 1885. John Dreyer catalogued Swifts object as NGC6951, ignorant of Coggias previous entry of NGC6952 and subsequent positional error of nearly 20 minutes. Upon the finding of Coggias error, NGC6952 was dropped and Dreyer made the proper designation correction in his Index Catalogue.

Visually, NGC6951 is a fairly large barred spiral located 70Mly away in the northern constellation of Cepheus, thereby making it a circumpolar object for many northern latitude observers. Located near the plane of our own Milky Way, NGC6951 can be a bit difficult to eek any real detail out of. A rather large but low surface brightness object, NGC6951 has a bright stellar nucleus with a bar extending W-E apparent in larger telescopes. The beautiful spiral structure, as seen in pictures, can be quite elusive. Dark conditions and larger scopes are needed to see the brighter eastern arm that wraps nicely around the galaxy.

Another factor that may possibly play a part in limiting finer visible details is the IFN. The Integrated Flux Nebula, or IFN is a structure of dust and gas that lies in intergalactic space just outside of our own Milky Galaxy. Not unlike Zodiacal Light which is reflected sunlight off of particulate in our own solar system, the IFN reflects the combined starlight of our own galaxy. NGC6951 lies in the direction of some very dense regions of the IFN. So it is possible that between its position near the plane of our own galaxy as well as in the direction of our IFN, finer details of NGC6951 may always be a challenge to us visual observers. (this is strictly my own theory of course)

So what observations have you had? Were you able to see the arms of this beauty? In what size scope?

And as always,

"Give it a go and let us now!"
