Re: OSC Optolong l-eNhance colour

Thanks Ivo, will certainly try this L-Enhance-UV/IR combo as you outlined. I assume when creating the two separate stacks in DSS you simply use a reference light frame from the first night's stack, add it to the 2nd night's stack as the reference frame but ensure it is unchecked; this should properl...

Re: OSC Optolong l-eNhance colour

Interesting suggestions from all, worth trying out to get the nasty blue/cyan gremlin pushed back a little (besides tweaking the RGB sliders in Color module). In the Compose module, after putting L-Enhance data in Luminance and Visual Spectrum in RGB slots, what would you set the Luminance, Color se...

Re: OSC Optolong l-eNhance colour

Another approach might be to use the l-enhance for what it was named for. Expose for several hours with the filter and use the stack as luminance data. Expose also without a filter (or an UV/IR cut) and use this as chrominance rgb data in the compose module. Not sure what result you would get. But ...

Re: OSC Optolong l-eNhance colour

Thanks Ivo; makes sense and appreciate the response; 100% agree with you as I follow the mantra of not changing things to looks "non-kosher"; I am all about keeping what I capture natural and scientific. Shooting from a Bortle 8 location doesn't exactly makes things easy capturing subtle details and...

Re: OSC Optolong l-eNhance colour

Team, following this thread with interest. I also use the L-Enhance filter extensively for emission nebulae with my QHY168C OSC, WO GT-81 APO and StarTools for all processing. I follow the Compose process by loading the same dataset FITS stack in the R, G, B slots and select L + Synth L From R(2xG)B...

Re: 1.74x N/R corrupts star centers

I experienced this same issue on a few star cores in images and had to use Heal to remove the black holes; intermittent problem.

Cheers,

Nick
