lukepower Posted December 12, 2014 Report Share Posted December 12, 2014 Around 200,000 light years in diameter, NGC 772 is twice the size of the Milky Way Galaxy,[2] and is surrounded by several satellite galaxies – including the dwarf elliptical, NGC 770 – whose tidal forces on the larger galaxy have likely caused the emergence of a single elongated outer spiral arm that is much more developed than the others arms.LRGB of 32 exposures of 10 minutes each, taken between November and December 2014. I am still gaining more exposures to reach a better s/n ratio Link to comment Share on other sites More sharing options...
