Thanks for posting these.  Those are beautiful and far better than any I've come across so far.

A barred spiral with a bit of interaction with the neighbour here (587727222471131319, although this refers to the bright spot in the spiral)

A nice barred spiral in Leo Minor constellation (NGC 3400).

It's a problem for me with classification. This galaxy is known as spiral. But it's hard to determine, from a picture, the direction od the rotation. I have a slight impression it's anti-CW.

It seems that GZ keeps me in Leo Minor beautiful region. It's NGC 3686, another barred spiral :) (with clear rotation here)

If you zoom out you can find a couple of beautiful objects there like:

NGC 3684

NGC 3681, barred spiral so it fit's this thread.

Nice!  A best barred spirals thread?  I could really get into this!

I posted this a while back in the best spirals thread, but I think it's more appropriate here...


ObjId = 587732053782626521

No, I don't think that there's any interaction going on here, Conan. The object at the bottom right of the image has the text-book morphology of an SBa barred spiral, and it has no distortion indicating that it's being perturbed at all. And, the arms of the galaxy in the middle of the image are too symmetrical for them to be a perturbation caused by another object.

I agree, Karhu.  :) :) :) Very nice image.
