NGC672
& IC1727
Galaxy
Pair in Triangulum
Uploaded

This
stunning duet in the constellation of Triangulum is often overshadowed
by other brighter galaxies in this part of the sky. Going beyond
the usual fare that everyone seems to spend all their time on
for the hundredth time, I concentrated on this fine pair. NGC672
is a 11.5 magnitude inclined spiral, type SB which as you can
clearly see here in the larger images sports some fine pink HII
regions. Its companion, IC1727 is much fainter at 12.1 magnitude
and is of low surface brightness in the arms which do not have
any discernible HII. The cute little edge on galaxy is much more
remote as you can see by its deep yellow color from intergalactic
reddening. This 16th magnitude anonymous galaxy is only 1 arc
minute in size and beyond the visual realm with this same instrument. |
