    The next things that is done, and it's next on my list for experiments is.... doing small video clips, 500 frames or so
    then these are stacked in programs like Autostakkert! 2 or Registax, it picks out the best 10 - 20% of the frames and stacks them

    That would be neat! I'm looking forward to it.

    The Sun 24 Nov 2017

    trying a B&W version instead of colour .... sort of have the feeling it gives better contrast of the visible structure ?

    A reasonable prominence upper left, a sprinkling of smaller ones elsewhere

    some small filaments here and there but the major feature is the long lasting filament

    PS .... Just to clarify ... I didn't image this in B&W ( greyscale) It was imaged in colour and then fully desaturated in Lightroom whilst doing the other processing edits

    Several really nice prominences on the sun today .... was first chance to do imaging in over 2 weeks ....
    Has been a mix of nothing much to image and when there was, it was cloudy for me
    But finally a clear sky and good prom's

    During the 30 mins I was observing/imaging, that smaller upper right one disappeared
    and the lower left one, I could see changes as material was falling back towards the sun's limb

    Are these stacked or just single images?
