Default ASTRO: The Saturn Galaxy?

Lots of galaxies in this shot and their distances can be very deceiving.
I took the shot for NGC 6470 which I call the Saturn Galaxy, complete
with E ring. If there can be a Saturn Nebula, why not a Saturn Galaxy?
It is about 60 million light years away. I put it off center to
capture as many others in the area as possible. Below it is NGC 6471
which is 350 million light years away and to the right (west) is NGC
6463. It must be a huge elliptical galaxy as its distance is 530
million light years. All distances are per NED. So as you go to larger
appearing galaxies you are really going much deeper in space, not closer
as size would seem to indicate. 6470 is classed as a spiral not a dwarf
but it sure is a dwarf compared to the others I have distances for. NED
didn't have data on the rest. I have provided a finder chart for the
brightest galaxies in the image.

The night I took this was awful in transparency, seeing and wind. The
image came out far better than conditions would have led me to expect.
Sometimes you get lucky.

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

Rick, that's a great bunch of galaxies. NGC 6470 really looks like Saturn in
a small telescope.

Oops, I made a typo in the ID of MCG+11-11-024. NGC MCG it's all so
confusing to my typing fingers. So I combined the two. Here's the
corrected version.

What's that bright blue object next to PGC 60721? Lower right.

It looks like it has jets.

It's just a very bright blue star that happened to hit a dust speck on
some optical surface. Most imagers clone these out. I don't.

Great images Rick

What's the magnitude limit on this pic?!

Not nearly as deep as my usual images due to all the gunk. Normally
limiting magnitude to my eye is about 6.5 but it was about 4.5 the night
I took this. That 2 magnitude loss appears to also apply to this image.
Normally I process down to 22nd magnitude though I can reach a couple
dimmer with more time and aggressive processing. In this case it is a
bit below 20 thanks to the gunk.
