NGC 2217 - Lenticular Galaxy in Canis Major

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.

A few quick facts:
  • Surface Brightness 23.69 mag/arcsec2
  • Major Angular Size 4.63 arcmin
  • Minor Angular Size 4.12 arcmin
  • Right ascension 06h 21m 40.35s
  • Declination −27° 13′ 56.90″
  • Distance 73 Mly 22.4 Mpc
  • Position Angle 113°

Instruments Used:
  • 10 Inch RCOS fl 9.1
  • Astro Physics AP-900 Mount
  • SBIG STL 11000m
  • FLI Filter Wheel
  • Astrodon Lum, Red, Green, Blue Filters

Exposure Details:
  • Lum 35X600 Bin1
  • Red 16X450 Bin2
  • Green 16X450 Bin2
  • Blue 27X450 Bin2

Total Time: 13.20 hours

Thanks for looking
Terry

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

Nice one

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!

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