When I stretched this channel, I noted the gradient wasn't as prominent.

Thanks Jase, I think the gradient was caused by the stray light from the last quarter moon as these were taken around the time the moon was rising.
Also thanks for pointing out the histogram, that one snuck by me on the last few steps of processing since I usually keep an eye on it.
I had a quick look and did adjust the clipping and there was a marked improvement (attached).
Cheers for that.
