Hi everyone
I'm not a normal forum poster but have heaps of images
I was reprocessing some older Gabriella Mistral images and found this b"bubble" pointed to by the arrows.
I used the Optolong L-Ultimate to obtain the image and Reprocessed it in Pixinsight
I may have seen traces of it in other images but this one seems very pronounced. is it really a thing?

It is just a bubble of OIII around those two bright stars and it is real enough if you got a strong OIII signal. I can barely see it mine but with just 15 min of exposure it is to be expected.

Thanks for that I have not seen it in other images. Just a trace in some Amazing what you can uncover when changing your processing techniques
