  1. I had problems stacking images when I took my Calcium H image on Saturday. Damian has suggested that i used too long exposures. Can i ask you what settings you had on your camera/exposure length/number frames per second etc.? How did you stack the images and improve contrast with processing?

    1. Sorry, Andy, I missed this one and the notification ended up in “junk mail”.
      The mikrokular works at 25fps but after all, it isn’t frame rate that is the potential issue, but shutter speed. In fact, I’ve tried imaging the Sun with the PD at a (claimed) very fast shutter speed and that showed no difference.

      All the rest is in the document I wrote for you a few months back
