It looks like the Lunt CaK modules are no longer available from Lunt. Would the Baader K-line filter work for viewing/imaging the Sun on a monitor and aid in detecting the bright ring around a sunspot visually? I know it cannot fully see CaK features but faculae may be more easily seen, hence the ring should be too.

Of course the CaK Quark is still available.

P.S. I later found the CaK module by Lunt. It's still there but has went up a lot in cost. The B600 costs about what a DayStar Quark does. Someone here recently mentioned something about Lunt maybe discontinuing them in the near future like Coronado has already done.

You can certainly do so James, it will enhance the faculae into the centre of the disc just like a Baader continuum filter enhances the granulation, but don't expect amazing CaK views, you will struggle to see the super granulation.

It’s a “ faculae filter “. I would find it still useful. I have a 430nm G band filter that I need to use more as well. The 540 gets a lot of use.

Today I picked out a faint ring around the double umbraed spot of AR12894. It was hard to see and I would have never seen it if I would have not been looking for it. Even in the SDO images it does not stand out.

It's hard to tell what is the ring and what is the faculae.

I viewed it at 83x using my Celestron 102 refractor with the Altair wedge and Baader 540nm filter. Higher magnification would have been useful if the seeing would have allowed it.

But is it the ring at all or just faculae?

Who knows if the ring is associated with faculae? just a height variable, that is the question :) there is plenty for us to study and observe.
