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.

Thanks for these Fabio! They look great. Pouring with rain here today so nice to see. In terms of CaK you can stop the scope down to 60mm and will improve things.

Hi Fabio,
Excellent images and your white light from today confirms the two pores ¿ mini spots ? I saw yesterday while trying to ficus White Light but had back luck in doing so. Now there seem to be a few more.

Re: Feb, 20 2021 - Sun in three lights
I love the WL, what a great shot I think I remember Eric saying that you need to lower the gamma and raise the gain for the CaK proms which is exactly the opposite to Halpha. I've never tried it but it might be worth trying.

Super captures Fabio and those spots have particularly shown-up so well. In fact a closer look at AR2803 shows that three-smaller spots to the north
are possibly forming and the main two may well have bridges in them..
Thanks vm for sharing

Very nice Fabio. They all look great. The first white light one shows more tiny pores than I can see on the SDO images!!
