Description

Hickson 93 is fausse rolex  a galaxy group in the constellation Pegasus (inside the square).  It consists of four main galaxies that all lie around 200 million light years away.  Arp 99 consists of the large elliptical galaxy NGC7550 that lies in the lower left of this image, the distorted spiral NGC7549 that lies just to the left of NGC7550, and lenticular/barred spiral NGC7547 that lies beneath NGC7550.  These three galaxies are interacting and some tidal/star streams can be seen around NGC7550 and NGC7547.replique montre de luxe 

This picture also contains NGC7553 which lies above NGC7549 and NGC7558 which lies above NGC7550.  Both of these are tightly wound spirals and are likely not associated with the others three (and lie around twice as far away).  In addition to these galaxies, there are many, many other dimmer galaxies in this image (down to the area of magnitude 23 or so). copie montre breitling
