Tail turning green?

[Scooot]

It might be my processing but the tail looks as if it now has a green hue to me. I managed to get a decent run of images for this on the 20th which is 65 15 second exposures wide open at f2,ISO400,135mm, on the star adventurer.I have stretched it as far as I dare  or perhaps too much. By the time I finished imaging it was only 13/14° above the horizon.

Not sure if it is or not, but many people have imaged green in the coma (as you have), so could be a trace in the tail.

Nice image anyway.

Thanks carol, I can only see it in the back end of the tail, it’s more pronounced on my pc than iPad.

There's been a definite green edge to the coma in recent days, I've photographed it as have many others. I think that's ionised cyanogen?

Thanks for the info. I’ve noticed quite a few images with green in and around the comet head but I must admit I hadn’t noticed any green in any tails, but that’s probably just me being unobservant.

The Swan bands in the green are becoming more obvious, the yellow sodium emission is reducing.

Many thanks, I’ve just googled it as well.
