Hi Paul,

That looks pretty cool.
The fact that you can see the DSO in your guider image is crazy.
is it field rotation at the top left and right? that is possibly to do with PA, not sure what the synscan method is.
Also, I'm no expert, but mono imagers usually get luminosity as 1x1 bin and RGB as 2x2 as 1x1 provides more finer details.
So shouldn't the Ha be 1x1 as that's going to add to the fine details?
Did you rescale it to 1x1 while stacking?
what if you scale the RGB to 2x2 and then stack with Ha as a test?
I'm looking at stacking an OSC Ha with OSC RGB as well, hence the question.

Cheers
