ASTRO: NGC 6985 and 6985A

NGC 6985 and NGC 6985A are a pair of peculiar galaxies in southwestern
Aquarius 2.5 degrees northwest of M72. It is a quarter of a billion
light-years distant. While the pair are at about the same redshift I
can't find anything on whether they are interacting or not. NGC 6985 is
classified as SBs)a: pec. The colons are the same as question marks
in that they note there's some debate about it being a barred spiral and
it being class a which refers to how tightly the arms are wrapped. It
is also a very red spiral. Its companion is shown as IB(s)m: pec.
Considering most irregular galaxies are strange I don't know what it
takes to make one peculiar. In any case they do make a strange pair.

The rest of the field has nothing with redshift data and very few of its
galaxies even listed in NED. All that are are shown in the annotated
image. Normally I'd not annotate an image with so little in it but it
has four asteroids, 3 of which are very faint. They show how poor the
night was. Note the trail of the brightest just northeast of NGC 6985.
At magnitude 17.8 it should be much brighter with the color images
strong enough to color the background but it is very faint with a
somewhat broken trail of varying brightness due to the constantly
changing transparency this night. Makes me wonder how much of these
galaxies, especially NGC 6985A was lost to the poor skies.

Rick,

if they are a billion lightyears away they must be quite large...
