I've been using the L-eNhance filter with my ASI533 and ASI2600 OSC cameras for a few months. I use a basic PI workflow, WBPP (I use to do each step manually) followed by some PP, e.g., ABE, color calibration, histogram transformation, noise reduction, image sharpening, and curves transformation. Images are pretty good especially considering the relatively short integration times of 120s subs for a total of 1-3 hours. However, the filter sometimes creates some undesirable color effects that PP really cannot clean up. I have seen some folks elude to ways to handle this for a better color image: 1) extracting the red channel from the image as it is basically Ha, using it as a luminance and then recombining it with the individually stretched RGB channels to get a better image and 2) extract the Ha (i.e., the red channel) and use it with the NBRGB script which I have never used.
From the above:
1- Do both of these approaches make sense (and are they in effect, the same with the same end result)?
2- If yes, which would sound like the best approach?
3- Can you please be explicit in your workflow steps if you provide any?
Thanks much,
Bruce
