Large, faint blue arcs

There are a couple of faint blue arcs in the top left corner.
Is this a known lens candidate ?

I am still learning how to work tools - but it looks good. The alignment is a bit strange - is that because it is a cluster, or is more than one galaxy being lensed?

There may also be some , more arcs further out - exciting! Can't wait for a Scientist to give their opinion.

Ooh nice ! Tx.
Yes, I also see some arcs further out. The cluster explanation looks plausible.

That could well be lensing. It's a bit too faint to really be sure. I'd like to see a bigger field to confirm that this is a cluster, but the fact that there are lots of similar colour galaxies implies that it is a cluster.
Clusters are almost always lenses, because they are so massive. But, cluster lenses are really hard to model because there are so many clumps of matter (galaxies) in them.
