Interestingly, it has a PK catalog designation of PK 294-00.1

Those details are from Sky Safari Pro 5

You found it!
The PK catalog must correspond to the PLN of TheSkyX.

Have a look here. There's a list of identifiers towards the bottom of the page: http://simbad.u-strasbg.fr/simbad/si...bmit=submit+id

Cheers,

I knew it would be out there somewhere! I found it on Aladin but I haven’t quite figured out how to get it to tell me object identifications. I’ve mostly just used it for star magnitudes.

Cheers Geoff, I was driving home last night and I think I’ve figured out a way of creating a H(b) channel to blend in with the blue. Certainly won’t help with any OIII signal towards the core of the PN however.

Thanks MnT Check our the 7 O-Clock position near the chicken, that’s where it’s located. It appears to have created its own cavity in the Ha.

Thanks Kevin, it’s actually really close to the chicken so as long as you’ve captured the entire region it should be in yours.
