Great pic! Your guiding really works, stars are perfect!

Do you have GradientX Terminator, it could remove the gradient.

Cheers

Spent a bit of time on the gradient, seem to get issues here and need to get GradientX to play with.

Thanks all, I am definately going to try and get more data for this.

L is luminance (no filter or a uv/ir block filter)

Wonderful picture, being an utter novice when I read that this was done with a CCD (webcam) I thought - wow!

CCD = QHY9 mono with 2 inch QHY filters

And then I looked up how much the QHY9 costs... Holy C**p, that aint no logitech!

Great very smooth shot.

Might be my laptop, but I see some diffraction spikes that are only on orange stars?
