Mike,
This looks like a short duration shot since the Trapezium is not blown out. The
fun comes wen you have to combine this with a long duration shot to get the
nebula as well as the Trapezium. It looks like you have some issues with
guiding so if you could clean that up it would help.

Subject: [AZ-Observing] First multi channel image
Here’s my first RGB image made from separate channels:

Not in Bernard’s league but a first step.
I probably processed it wrong. (My “Inside PixInsight” book is supposed to be
delivered on Thursday.) I calibrated, registered, and integrated each of the
channels separately. Then I registered and combined those individual channel
“masters” into a single RGB image and applied a little histogram equalization
to it. I probably should have calibrated and registered all of the raw images
together in one operation. Then integrated each channel’s registered images and
then, combine them into a single RGB image. But hopefully the book will give me
some processing ideas when it comes. Like what to do with the L channel? :-)
