ASTRO: ARP 65 has lots of friends

A temporary return to Arp galaxies. I have a lot to take but this is
all I've got to process right now as I have a bunch of other stuff to
work on.

Arp 65 (NGC 90) is part of a large cluster of galaxies known as SRGb 063
located some 240 million light years away on average. Some catalogs,
incorrectly, show Arp 65 as NGC 91. There are so many galaxies in this
area that early astronomers kept finding more and and in the rush not to
be scooped sometimes identified stars as galaxies. That happened in the
case of NGC 91. It is now known to be the blue star directly south of
Arp 65. Yet some catalogs claim that star is Arp 65 creating some
confusion. Other stars in this group were also assigned NGC numbers
adding to the confusion. My field isn't large enough to get all the
group. I'll make a separate post with an annotated version of the
image. Arp 65 is the spiral with drawn out arms in the center. It is
thought the culprit whose gravity rearranged its arm is NGC 93 to the
east (left). Indeed, it too looks distorted.

Correct domain name is arvig and it is net not com. Prefix is correct.
Third character is a zero rather than a capital "Oh".

Great images Rick.

Great picture Rick. Especially the pair in the middle has some verym good
detail.

Their tidal interaction helped create a lot of that detail. Though they
are the only two large spirals in the group. Still I like the whole
field and the hint of arms and a dust lane in NGC 83. I hadn't expected
that when I took the image.
