New to me! Thought I would share... Tadpole bubble!

I was looking at some starless images of the southern tadpoles and I realised that there is a lovely OIII bubble, above the tadpoles. Unless this is a processing error on my side (very possible!), this is a fun object because it seems to be entirely in OIII, not sure what the name is. Maybe someone can confirm this is a real target not an artifact?
Anyway - if real, an interesting target for those of you with longer FL.
The OIII image details:
25 X 300s 7nm Baader OIII filter
ASI2600MM
SkyRover 115+0.8 reducer/flattener
Processed in Pixinsight, PS
plugin:StarXterminator

I believe that is an artifact. A filter halo that is left behind when doing star removal. I've got the same artifact with my Baader 7nm OIII filter on my 1600MM.

sorry to burst your bubble....

It's no artefact it's definitely a bubble look at my attachment of my image
