Heron galaxy and friends

 Hello,

for my first post here an image from last month, shot from my garden in the suburbs of Paris (Bortle 7/8) with my 200/800 newtonian (details below).

The most interesting object is a pair of interacting spiral galaxies in Canes Venatici, NGC 5394/95  or Arp 84, also known as the Heron Galaxy, 107 millions l.y. from us. The field contains also the barred spiral NGC5378 on the right and, in between, the lenticular galaxy NGC5380.

 

Here is the full-res image

and a crop on the heron:

Thanks for looking,

 

Dan
