Type Pec (Liner) LIRG

Dr Arp classified ARP 243 AKA NGC2623 in his Atlas of Peculiar Galaxies as "Galaxies with the appearance of fission". This is what a high speed head on galaxy collision in the late stage of merging looks like. Arp 243 is so bright in infrared that it is in an unusual class of galaxies called LIRG (Luminous infrared galaxy). In the tidal tails there are hundreds of star forming regions that have been charted. Arp 243 is 250 MLY away and when I look at images of it I always expect to hear a loud crashing noise.

My brief notes with my old 25" reflector on Arp 243 say, ARP 243 small very bright mottled core with faint arms that grow with averted vision. Looks like a lawn sprinkler. "Very Cool"

I wonder what is the smallest aperture that can see the tidal tails in Arp 243 be sure to,

"GIVE IT A GO AND LET US KNOW"

GOOD LUCK AND GREAT VIEWING!
