zoomed night Sky Comet?

Best on black. We went out to try to see the green comet. I'm not sure that this was it, but I am perplexed by the black arrow that seems to go through it. Anyone who knows more about astronomy able to help me out?

I'll be interested to see if anyone knows more about this - quite interesting and a super shot

Unable to provide info but I find it to be an amazing capture!

I googled green comet images and the round part of yours looks similar to some. I didn’t see any with the arrow, so I was wondering if you could have also caught a contrail passing in front of the comet.

Wow, so interesting!

Great shot. Very interesting.

Asked David what he thought it was and he thinks it may be the
Spindle Galaxy and the black line is a dust cloud.
