Thanks for the nice feedback fellas glad it was worth a look

As for the faint Jet like feature, it is hard to confirm whether it is an actual "jet" say like these brighter ones emanating from NGC 1097 but the "feature" is indeed real as you can see from THIS Deep UK Schmidt comparison I have compiled. I have presented it quite small to simulate having the images farther from you on the screen and this makes the faint features more obvious, I also further lifted the contrast in the UK Schmidt image as the version I accessed was not contrasty enough to really show the feature well. I think the AG12 has gone deeper actually, at least in extended diffuse features anyway..? I would imagine such a feature is down around 28mag/squ arc sec?

The 48" UK Schmidt image was nearly 6hrs of exposure and composed from 5 emulsion plates and then amplified and contrast enhanced by David Malin.

Now under dark skies and especially with the new SX gear, this AG12 scope keeps amazing me with its capabilities

Lewis, that object could be a PN I guess but it's more likely a distant galaxy association I'd recon

DaveU, thanks for that link, I am sure there is a relationship then
