Skies are ok at the moment but i'm really starting to loathe smoke.

Thanks George, I have been lucky with the smoke.(touch wood
) I know tracking is somewhat below average, the eq6 is about 12 years old now unopened. I'm either going to do the Rowan belt mod and Zero Backlash Worm Mount replacement or.....just get a EQ8 and be done with it. I cant get any better than .8 rms on guiding and that's only for a short duration. Probably a lot to be gained here as you said the stars are somewhat getting away from me haha. painful
but that's all I have to work with atm even after adjusting the RA/DEC gearing.
Pixinisight process:
DSS:
Stack and align, best 80% of subs.
Mainly because I'm familiar with this process.
Pix:
Star align
LRGB Combination (RGB combine)
DBE on rgb and the lum
Colour Calibration rgb
Histogram Transformation rgb+lum same level
HDR Multiscale Transform
LRGB Combination (adding lum to rgb)
Basic Colour saturation
Histogram Transformation and maybe curves.
That's my work flow to date. I'm guessing there is more I can do but when the stars are the shape they are I don't think venturing any further will help
Be good to get some direction on refinement, but I think most if it falls back on the guiding and mount respectively.
Current imaging chain recommends a good mount and tracking.
The ideal pixel size for OK Seeing (2-4" FWHM) seeing is: 0.67 - 2" / pixel.
This combination leads to slight over-sampling. Will require a good mount and careful guiding.
Cheers,
Dan
