NGC 7217 is Sb giant with a moderately bright halo that brightens towards the center. It has a prominent nonstellar nucleus, and across the granular disk there is a faint internal ring of low surface brightness.

The shot:

EAA is a very simple way of observing the sky and at the same time taking graphic records of what is seen. Judging by the post visits, the subject is quite interesting for people, of which I am very happy.

I'll keep posting weak little beauties :thumbsup:

That's great!

Also, the very latest 1.7 alpha introduces walking noise reduction to the Denoise module. It may help some people doing EAA where dithering between frames is not always possible or desirable.

Clear skies!

Arp 13 / NGC 7448 in Pegasus is a mag. 11,6 spiral with detached segments and high surface brightness, according Arp's catalogue description.

The chalenge is found the fading textures to the N-NE and S-SE (spiral structure)

NGC 7635 is about 11,000 light years away. The "bubble" in NGC 7635 is about 10 light years across. It was created by a fierce stellar wind from the hot, young, massive central star, which has blasted out the structure of glowing gas against denser material in a surrounding molecular cloud

NGC 457 is one of the finer star clusters in Cassiopeia. It was discovered by Friedrich Wilhelm Herschel in 1787. Besides its official name, NGC 457 is also known as the "Owl cluster" or the "ET Cluster".
