ASTRO: NGC 6745

Another I wanted more color data on but the clouds had other ideas and
now with the bright moon and still more clouds I've decided to go with
what I have. This guy is in Lyra, a constellation not noted for its
galaxies. But it is high over head where the #$%@# clouds are the
thinnest so it became a target one somewhat cloudy night.

This is variously described in the literature as two, three and even 4
interacting galaxies. Actually it is only 2 but the distance of over
200 million light years and the small size of the galaxies involved made
it difficult to tell what was going on. It was, before the interaction,
one normal spiral plus a tiny dwarf of unknown (to me) type that grazed
it. This left the arms of the spiral distorted and rather blue along
the path of the graze. The north end (the end nearest the companion
that caused all the ruckus) is a mass of giant blue-white stars and can
appear as a separate galaxy. So can a knot of new stars in one of the
spiral arms. The "bullet" galaxy is seen faintly due north of the
bright knot of blue-white stars. Hubble took the definitive shot though
the "bullet" is mostly out of frame.

I thought this would be one not posted here before but see Stefan beat
me to it years ago -- twice In fact this was the first object he ever
posted according to my notes. Hard to find one he hasn't yet done!
