Face On Spiral Galaxy NGC2857 (Arp1)

            This is the face on spiral galaxy NGC2857 and is also the first entry in the Arp catalog. It's Arp class is "spiral galaxies with low surface brightness". NGC2857 shows two very long thin spiral arms, as can be seen in my image.  The galaxies of the lower left are NGC2856 and NGC2854, they are interacting galaxies and also listed in the Arp catalog as Arp285. These will be imaged at a later date using the Meade 12” to gain additional data.
