27th Nov spots in WL and CaK

Post by robert »

In between wintry showers the seeing was about 1 arcsec or less which is really good for here.

Wow!! superb imaging Robert, I love the animated WL/CAK :bow :hamster: James asked me about what I see when I visually look at CaK, I see exactly what your CaK shows. You always manage to get perfect real colourisation, I've never mastered that :bow

Thanks vm Robert for your excellent captures today and the animated pair of CaK and WL certainly show the differences very well.

Thanks for sharing

I love the GIF animation. CaK is certainly better at showing plage/faculae than continuum is.
