Ngc6357 in the dewy moonlight - Now with Ha data

Tried out the QHY10 camera with my 5" apo last night and managed to incorporate a meridian flip to gather 4hr of 10 min subs on this nebula in Scorpius. It was quite faint however even with the moon quite bright in the sky I was amazed that I could get away with 10 minute subs. But it was wet, wet, wet last night and I had to turn the heater on in the observatory while I collected my darks and flats etc which dried things out a bit so in the morning things were not covered with moisture.
Stacked in DSS and processed in PS3. I must get to learn PI one of these days but my head is like a sieve and although I follow the tutorials I can never remember them in full.
Comments welcomed.


Ive now taken Paul Haese'suggestion and added some Ha data to the image which I think lifts it. Thanks Paul.
The Ha data comprises 10x10 min shots with QSI583wsg which had a horrendous gradient due to the moon almost on top of the object. Aligned with Registar and combined in PS3
First image RGB, second HaRGB
Comments welcomed as usual
