Hi eveyone,

 

NGC 520 in Pisces is not easy to observe. Depending on the conditions, a sky a little less dark or a little more humid, and you can hardly see it. I observed it in two different locations, both Bortle 4.5. In September, impossible to detail it. This time, in November, it showed his face.

Located about 100 million light years away, it is actually 2 colliding / merging galaxies. It also bears the Arp n°157. Its mushroom shape reflects a very disturbed morphology with tidal tail and dust lane.

 

Clear skies,

Francis

I absolutely love these kind of targets and drawings.Well done Franc,excellent. Between your piece here and Jef De Wit's sketches of obscure OCs earlier I'm in hog heaven (american slang for very pleased)!

Francis,

 

Very nice sketch an persistence to get that fine sketch.

You can tell this is a pair of colliding galaxies in your sketch.
