    It's been some time since I visited boards and even longer since I posted anything. Thought I'd share a few images taken this year. Upgraded from unmodified DSLR to RGB imaging with a mono CCD. Still trying to scale a new learning curve but feel am making some real headway with it.

    How does that work? Multiple exposures through different filters?

    Hi Mikhail. That's right, multiple images are taken through luminance, red, green and blue filters. Calibrated and combined in pre-processing. Then further stretched and enhanced in post-processing.
