At over 200 million light years, NGC 6935 & 6937 are two small galaxies in Indus with nicely contrasting morphology. The two galaxies are indeed close to each other, with NGC 6935, the tightly wound spiral with prominent blue ring of star formation, being the closest of the pair at about 209 Million light years, while the more open blue spiral NGC 6937, sporting a vague bar, is slightly farther away at 220 million light years.
Of course at these sort of distances both appear only 2 arc min in angular size, so this was another test of my site, requiring good seeing to do them any justice.
I collected the data last Thurs, Fri and Sun nights, over New Moon (with the usual beer drinking
visual observing...and singing
), and luckily Friday night was cooperative in the seeing department, providing above average to rather good seeing most of the night
...so I took the bulk of the 10hrs Luminance on this night.
The full frame includes literally hundreds of background galaxies and a couple of galaxy clusters.. all at clearly great distances
...so it is worth having a look at the full frame full resolution version
NGC 6935 / 6937
Full Frame Full Resolution (have a swim
)
