Hello,
Pleasant imaging session: today the transparency wasn't exceptional, but the air was really still.
Had a look at all the wavelenghts, starting with white light of the emerging AR:

Then tried a couple mosaics in Ha and Ca-K: Microsoft ICE is really intuitive to use

I also experimented capturing the prominences in Ca-K, however the glow and ghost images (due to reflections ?) are really annoying. I am using a stock Lunt Ca-K module: all suggestions are welcome.
