CaK activity 4th Feb 2022

[Merlin66]

The active areas, showing very well formed sunspots, AR2936/38/39 and 2940 make a very nice layout.
There's another large unnamed AR just coming into view in the north east - multiple spots...
I used both the MiniSHG (see the proms) and the DIY Cak Filter on the Custom Vixen 90 (for the detail)
Enjoy!

Your CaK images are 👌🏾 - the framing on the 4th one is excellent, a real sense of motion & energy 👍🏾

Thanks for the feedback, appreciated.

I'm quite pleased with the performance of the Vixen Custom90 at the CaK wavelength.

NiCo10,

The Lunt CaK module is still available. https://luntsolarsystems.com/product/lunt-calcium-k-modules/

Note, the Lunt is quoted as 2.4A bandwidth. My DIY version is a 25mm double stacked assembly and gives 1A bandwidth.
