Hello group,

 

Arp 188 has only a small apparent size due to its distance of 420 million light years, but since the galaxy shows interesting details and especially a large tidal tail, it went on my todo list. The tidal tail, with an extent of 280,000 light years, is thought to have been formed by an encounter with a smaller galaxy about 100 million years ago. There is also a distant galaxy cluster in the field with a redshift z = 0.251, which corresponds to a light travel time of 3 billion years.

That's a great image, very good detail in the galaxy!
When clouds go away that's a very nice target to try as well.
Thanks for sharing

That's a great image of Arp 188.  I spent 15 hours on it several years ago, and the result was a huge disappointment.  You've actually got some detail in the colors of the core, which I thought was never going to happen with any scope in the 11-12" range. Thanks for sharing!

Very nice, I love these challenging targets. Everything has to work perfectly, on top of conditions being near perfect. Also a dark site helps.  Looks like cosmic disc golf!
