A couple of planetary nebulae, Heckathorn-Fesen-Gull 1 at lower left and Abell 6 at top right. The star that created HFG1 is V664 Cas, a binary star that's moving through the interstellar medium quite quickly. This motion is causing the blue shock front at lower right and leaving the red trail.

An intriguing field Rick. I'm impressed with the array of objects that you and your team manage to find for imaging. A great capture of two PNs in the same field. Thanks for sharing.
Really great shot of these two Rick. The bow shock ahead of Heckathorn-Fesen-Gull 1 (They should'a named the Sydney Ferry that ), is intriguing and although not common, there are a few of these out there

Thanks, Rodney! We do spend a fair bit of time on research.

Ta, Mike. I find it amazing how much variation there is between different PNs. Would be interesting to try modelling them in 3D.

Thanks, Steve. I think this one was proposed by team member Scott Johnson.

Honestly though, I would have expected the OIII bow shock to be a bit more smooth at 25hrs integration. Did you do any kind of noise reduction?
Thanks, Joel. Even with ~25 hours on each NB channel there was quite a bit of noise - it's a dim target. I did some very slight nr but tried to leave a little grit. It's possible that my processing emphasised that more than I intended. I'll give it a day or two and decide whether it needs a repro. I try to err on the side of leaving too much noise rather than getting that plastic look.

So...what processing software do you use again Rick .....have you tried Photoshop?
