This is a work in progress and colour will follow when the moon goes away. It's quite a deep Hydrogen Alpha shot (I may go even deeper) which shows the faint shell structure around NGC2438 and the faint Calabash nebula, a proto-planetary nebula, to the lower left. Mike's recent great shot also shows the Calabash quite clearly too.
Faint shells and a baby rattle, not seen on IIS before and now two in a week cool
Good confirmation actually, that very outer shell is not complete...maybe with heaps more exposure the missing section might show..? I gave up (impatient )
Nice work, Steve. Looking forward to the colour version!
Thanks Rick. Hopefully shouldn't be too long.

Thanks Mike. Not sure exactly where I'm going to go yet - narrowband or HaRGB - perhaps both. A long SII exposure might be interesting because the Calabash contains lots of sulphur hence the alternative name of rotten egg nebula.
Because there isn't much else to do at full moon except image in Ha I added some more to this image and it's now up to over 11 hours. Nothing much added to the overall result except it looks a bit cleaner now because I didn't have to stretch it as much.
cool
