Nice and sharp and guiding looks spot on.

Very well done.

Thanks Matty

I actually don't mind the varying star colours. Gives the image a bit of spice.

Your data capture is great, infact I am amazed how good it is given the significant mass of your scope and not so big mount. Kudos to the G-11 for sure

Processing... sucks a little. I have no hard and fast rules, other than a warm human eye can sense a vast dynamic range and this is what I try to replicate in images. NGC2070 is a bit like M42 ie. vast dynamic range and needs much gamma stretching to show all the information in the digital data.

Peter,
Many thanks. Yes the G11 is a beauty. I've been trying to stretch the images by setting black points in darkest areas of sky and white points on white stars and ensuring all 3 levels are set appropriately (usually somewhere between 8 and 12 for black and 255 for white). Is that what you mean by vast dynamic range? Alternatively I suspect I can image a bit longer and capture a bit more of the faint luminosity which I suspect might be missing from this image thus accounting for lack of dynamic range? Am I on the right track?
I suspect I've stretched the data I have as much as it can be, it might now be a matter of capturing longer exposures, I think, is that right?
