Can you help me find ANY Lunt CaK filter examples for recording CaK filaments??

I've had a go with my CaK PST this morning but I don't think I can see anything. Unfortunately since removing my eyepiece filter (rust) I have not been able to get such good contrast, I think the band is much wider with the Baader CaK filter

I know that Robert from the Isle of Skye has caught one in the past

Alexandra,
Thanks for that.
A very surprising result based on my findings to date.

Hi Ken

I remember recording a very faint CaK filament not long ago. I will have to find the image though...

I'm also processing today's images, maybe the filament will be visible

Hi Ken

Check out this mosaic, CaK & Ha (20211122). The filament is faint but visible in Ca-K

best regards

I've got quite a few Ken - I searched CaK filaments on my website...

Thanks for the info and images of CaK filaments.
I've tried to summarise what I've found:
