Little Sombrero Galaxy and some distant galactic fields

 Hi,

Here are my latest pictures with the usual setup (8" f/4 with ASI183mm).

NGC7814 is an aesthetic edge-on spiral galaxy in Pegasus, 33 millions l.y. away, with a very sharp dust lane and many globular clusters in the halo. I imaged it from a darker site than usual (about Bortle 4/5), with good seeing (FWHM 1.6" on the stack):

The other ones are from my Bortle 7 backyard 20km from Paris,

Arp 278 or NGC 7253 in Pegasus is an interesting  pair of colliding galaxies, about about 210 millions l.y. away. The aesthetic face-on spiral galaxy PGC 68543 nearby seems also to interact with a small companion.

The main galaxies of this field in Pegasus, the barred spiral NGC7342 and the edge-on galaxy NGC7345 were discovered by French astronomer Stephan as the Quintet nearby. Together with the PGC galaxies nearby on the image, they form the cluster WBL685, about 400 millions l.y. away.

Abell 2634 is a galactic cluster in Pegasus, about 380 millions l.y. away, whose main galaxy is the elliptical NGC 7720.

The NGC70 group (Arp 113) in Andromeda, a tight group of galaxies 320 millions l.y. away, with many others in the field:

Arp 112 is a tiny pair of interacting galaxies in Pegasus (spiral NGC7806 and elliptic NGC7805) which is actually interacting with a third one, the arc-shaped KUG 2359+311, 216 millions l.y. away. The field contains also the barred spiral NGC7819 as well as many other distant galaxies.

Thanks for looking,

 

Clear skies,
