Finding new PN's in plain Sight

Here is an image of very deep OIII minus continuum stars.

There are quite a few putative PN's in this field. I bet none of them have been catalogued.

It will take verification at far longer focal lengths to get to the reality.

Wow first thing I did was look up what putative means then looked at your image Bert.
It's a lot to take in, would one of the mapping utilities identify many of them or will they be called bert1 Bert2 etc

So much in that shot

It only occurred to me after I looked at the differential image David that this may be a way of finding dim PN's in a very cluttered star field with lots of nebulousity.

I do not have the knowledge to identify or patience to check on whether an object is already known. I offer it to all of you as an other method of finding unknown objects.

Anyone is welcome to use my images to hunt these down. There are enough Berts in my family without adding more to the sky.

Did you see the NII-Cont version?
