NGC 2217 - Lenticular Galaxy in Canis Major

[TR]

This is NGC 2217, a lenticular galaxy located in the constellation of Canis Major, The Great Dog. It has a set of spiral arms tightly wound with a bluish colour. They form an almost circular ring around the galaxy. This blueish colour indicates the presence of hot, luminous young stars born out of interstellar gas clouds.

Contrasting this is the central bulge and bar region. This area is golden/yellower in appearance as it contains older stars. I especially love the two thin tight arms around the central bar. It looks like an eye looking back.

I didn't find many renditions of this galaxy. I guess it's on the small side. I think it's an interesting object. Those almost circular ring arms are very cool.

Another lovely galaxy Terry (gotta love galaxies, they are the best :love:) and always good to see galaxies in constellations less travelled for them :thumbsup: Reminds me of a cross between NGC 7098 and 1291 :)

Looks like you are knocking them out of the park of late.

Nice one :thumbsup:

Great image Terry,
you've done well.
I did find many renditions of this galaxy and they show that bright bar
which you picked up very well:

Great shot! Very interesting structure on this one - reminds me a little of NGC5101. Wonderfully resolved with beautiful detail!

[TR]

Cheers Peter. Galaxies are so far out of the park. :)


Thanks Allan


Thanks David. Yes, it does look like NGC5101. It even has those two thin arms close to the bar. More image scale would help :thumbsup:

Many thanks Peter.


Thanks Adam. That is about the best comment you can get, "colour balance is very pleasing" Cheers.
