Good call with the colour.

Thanks Dave,
The waisted 3 to 4 hours of Luminance was a real bummer. I don’t even know if it’s worth shooting 10 , 20 or 30 sec Lum subs as I’d need probably 500 to 1000 subs to achieve decent SNR. Really short subs are still noisy with some signal.Luminance is suppose to provide all your fine faint detail, but I certainly couldn’t see that after a stretch.
I’ve been reading a few Posts on CN and a lot of folk opt for capturing more RGB and using a Synthetic Luminance ( like I did on this image but unfortunately no where near enough RGB )
Seeing might have been poor but it didn’t reflect in my guiding , guiding was really tight , almost flat lining for my mount
I tried SV Decon in Startools to try and deblur the atmospheric effect but due to the massive noise reduction plus reduction in overall image size in pixels , this algorithm didn’t work that well, so I abandoned it ( it works a treat though for Narrowband or broadband in darker skies )
There’s no substitute for Dark Skies like down at my Dome !!
Cheers
Martin
