Arp 241 and distant galaxies

[Mike JW]

Hi, I have just been going back over some earlier Arp shots.

Arp 241 in Bootes, Arp classified this galaxy as having the appearance of fission , that is pulling apart/breaking up. Galaxies do not actually do that by themselves.. Later images have shown that Arp 241 is really two galaxies doing a merry dance and in time will be come as one. I just managed to catch the swirling arms as a result of the merger.  Arp 241 is the double blob in the centre of the shot. However as I studied the shot and then looked up decent images I realised that some of the noise is in fact distant galaxies. I have drawn lines to some of these distant galaxies and the number by them indicates the distance in billions of light years - mind blowing stuff. Must re-visit this one and mess about with time/subs/settings and focal length.

Details: 20 x 15 sec subs, C9.25 @ f 4.4, (March 2019)

Just returning to Astro and this deep galaxy hunting is inspirational!

Hi Tony, it is also addictive. Mike
