NGC 5463 galaxy and group in Bootes

So I was working my way through another list of galaxies last night. One of them was NGC 5463 in Bootes.

At the time it was just another nice find in my 16 inch. I noted I could almost hold this galaxy even with direct vision. I could see the star below and right of the galaxy.

Initially when I looked up the details it was just another typical mag 13 galaxy. I looked up the red shift and this was 7092km so pretty far away at just over 300 million light years.

Then I looked up NGC 5482 which I had looked at next. It was also just over 300 million light years away.

So had a stumbled on a group of galaxies at 300 million light years away? The answer seems to be yes. Here is the list of all 30 ish of them. They are all around mag 14 and 15.

When I was researching groups in 3D a while back I did find a blob of galaxies at 300 MLY in Bootes so I think this is a group within a larger gathering of groups all at this distance. You can see 5549 on this image which is in the 5463 group.

Here is a better image. I cannot find any amateur images? Go on someone, It looks an interesting interaction. ARP seems to have missed these!

Looking at the image there is another galaxy NGC 5463 B. It is to the top left in this image. I did not notice it last night. Mind you even the Gottleib with his 17.5 inch calls the companion extremely difficult. I might try again and all of you guys out their with the big dobs with your 1/10 wave mirrors can try it at high power :)

Looking at my logs I have seen NGC 5463 / NGC 5482 / NGC 5546 / NGC 5549 / NGC 5519 / NGC 5436/7/8 in this group

So go out and see how many galaxies you can spot in this group.

Skysafari has 5463A listed as mag 14.  as it's pretty small at least this may be in range for a 12", can't vouch for its companion though at mag 15. None of the others are showing on Skysafari so I guess they are fainter than mag 18.5.

Hello Mark hope you are keeping well and enjoying that 16".

On Interstellarum NGC 5463 states it visible in an 8" but I doubt that. There are lots of galaxies very close to the right of NGC 5463 which should be visible in a 12" according to Interstellarum but I think you need a very dark and transparent sky.
