Abell 2744 again but this time with the available light from some deeper infrared data, specifically from the F160W filter. Any of the very, very red galaxies you see were very faint in the previous images or went undetected. In short, we can see the redder galaxies better with this one.
I think I like this one the best so far because of the extra infrared data and also because the closer crop lets us see the lensed galaxies easier. My favorite part is in the lower left quadrant of the image. There is a faint spiral galaxy which is blue and has a red center repeated at least three times that I can perceive.
Now there are lens models!

This data is all available here.

North is NOT up. It’s 6.6° clockwise from up
Hubble data is public domain, but I put a lot of work into combining it into beautiful color images. The minimal credit line should read: NASA / ESA / J. Schmidt
