I suggest that if you intend to visit, book passage on a very, very fast vessel, so that time, as you experience it, will be much, much less than 11 billion years.

As a practical matter, even if the vessel’s speed is constrained only by accelerations that humans can survive, it might take several lifetimes to complete the journey.
To your twin brother on earth the journey will still take at least 22 billion years, so things might change in the meantime. The sun will be dwarf, and the earth will probably not survive, but if it does, it will be little more than a cold cinder. It’s unlikely you will recognize your old neighborhood.
“Non-visible/optical images (infrared, UV, gamma, microwave, radio, etc) are typically converted to false color images in order that there is something for people to see and study.”
I don’t know which type of eye-candy I like better, super-enhanced digital images of galaxies, stars and nebulae light years away or some of the cars I’ve been seeing in HDTV on the Barrett-Jackson and Mecum auto auctions.
“What exactly are you referring to? “
11 billion years does not equate to 11 light years.
Years is a measure of time, but a light-year is a measure of distance.
It would still be 11 billion light years away, whatever that would be in miles or other distance unit of measure.
I explained in post 2 that I simply made a mistake leaving out billion in the first part of the post, but had it in the final part. And I know that a light-year is a distance. I think I made that pretty clear.
“That is, it’s ‘11 light-years away’, where ONE light-year, the *distance* light travels in a year at its fixed speed of 186,000 miles per second, works out to about 5.9 TRILLION miles. And so this ancient galaxy is 5.9 trillion x 11 billion miles away.”
...and as was pointed out by another poster and in the piece I followed up with on “Distances in an expanding universe”, the actual distance may be much more than 11 billion light years.
Kind of look looks like a swastika?
That’s one interpretation, by far the most common one. There’s another one, you say, ‘Civ? That guy, he never gives up... ;^)

Long ago and far, far away! LOL!
Cosmology and astronomy are simply fascinating!
I remember back in the mid-eighties when galactic lensing was first discovered. It was puzzling at the time and was described as McDonald arches in deep space. LOL It wasn’t much longer until explanations were rolled out.
Einstein once said that an Earthling observer, if his eyes were like telescopes, could see the farthest objects, and if the observer had ENOUGH time, eventually he would see...
The back of his head!
Oops! Post 33 was meant for another thread.
Sorry.
Here is video of the flight of the space probe.
Turns out there is a giant little girl in that galaxy.

That was because he mistakenly believe the universe, due to gravitational attraction, would eventually collapse upon itself. ie, be a "closed universe". But observations at the time seemed to indicate that the universe was "static". This was why he concocted the "cosmological constant", which was to be some mysterious anti-gravity force that would precisely balance out regular gravity.
Then when it was discovered that the universe was actually not static, but rather expanding, he called his introduction of the CC the 'greatest blunder' of his life. Turned out many years later that the universe is not simply expanding, but accelerating, as if there actually were some anti-gravity force pushing galaxies apart.
A billion here, a billion there, and pretty soon you’re talking about real time................
Yes, I have wondered for years why nobody ever thought of that.
This ‘old galaxy’ might just be US!..........
