Lucky you Nigella, all we have had is cloud and mist as well.

There was blue sky everywhere except where the sun was with mist passing over it, quite frustrating again when everywhere else was clear, typical, still it's an observation nonetheless.

Sometimes when it's really misty and foggy I've seen sunspots with the naked-eye, or at least I did many decades ago when my eyes worked properly.

Yeah, I've seen the spots through mist before. Well the larger one's, lol.

Is it possible to view directly in Cal-K , like H-alpha, or is it for imaging only?

I would say purely imaging because its at the ultraviolet end of the spectrum. I've heard of people after a cateract op saying they can and some with younger eye's, however. I've looked through the lunt calcium II K filter and all I've seen is a blue/purple disk with no details.
