Well done !!
How much data was captured when the moon was up as I’ve noticed since Mono imaging with a dedicated 3nm Oiii filter , the moons glare really retards detail and adds so much more noise than obviously the Ha and Sii counterparts. It surely must affect the Oiii in dual bands as well.

Thanks Martin I appreciate you comments and encouragement! Ngc3132 has a very bright core but the outer regions are extremely faint which makes processing a challenge to get one without sacrificing the other.
I had 12 hrs under the moon, but the final 6 were under a full moon very close to target. This data was pretty noisy and I almost chucked it but managed to salvage it in the stack luckily. I’m not sure the noise was restricted to the o3 channel as it seemed to affect both (to a degree). Hard to say…
I was very fortunate to have 2 moonless nights in some of the best seeing I’ve ever had here. This is where pretty much all the fine detail came from. I’ve attached a screenshot of a single frame and my ASIAIR guiding on this night. My 20yr old eq8 still getting the job done!!
