March 20th in Ha and Ca II K
The seeing conditions were less than ideal this morning, but stable enough at times to capture some close views in Ha and Ca II K, although most of my data ended up in the bin as a blurred mess.
First up is a full disk in Ha. There's almost nothing to see at this scale, except for a small newly formed active region towards the eastern limb. There were no filaments that I could see and only a couple of faint proms that are missing off this image.

The active region and associated plage is more discernible in this calcium II K image taken on a 72mm f6 refractor and B600 Lunt CaK module with an omega filter and Baader CaK line.

Looking more closely in Ha, out of 8 SERs this is the only one that survived processing to give something half decent. It's a little active region, but I'm not entirely sure where. This was captured using my 150/Lunt 35 mod.

Likewise in Ca II K I was struggling to achieve sharp focus and capture usable SER files. This one was taken on my Tecnosky 125mm with a B1800 CaK module.

Thanks for looking.

Beautiful crisp and clean images.
I tried to image today, but it was hazy and with jumping seeing.
Lets see what I got as soon as I process the session. }
Good day and keep well,
Eric.

Very nice view Stuart. Fighting clouds today I could never manage to see that tiny AR. CaK shows it very well!

Conditions/seeing has been challenging here as well.
Still a very good result though, Stu. Nice work.

Great images are usual, Stu, H alpha at full res is impressive.

Re: March 20th in Ha and Ca II K
Many thanks everyone.
It was supposed to be sunny today, all day.... however, it looks like the clouds are set in for the duration. SAT24 shows a broad band up and down the UK with the wind from the east not making any headway pushing them out to the west.
Ah well, there’s always tomorrow.
Thanks again and stay safe, everyone.

A beautiful set of images, Stu. Very clean FDs and great close up of the chromosphere. Well done !

Really nice set of images Stu, these came out well. Seeing today was bubbling too.
