A little bit of my first ever attempt at barlowing the Calcium stack today and got a good taste of how difficult Ca K can be in moderate seeing and at 3x magnification...
Wind was cranking 40mph when I got going this 8am, the images kept snapping off till the cloud rolled in ending it at 8:53, seeing all over the place with the gusting winds so a challenging session to capture all I could swapping lights, mags and refocusing as quickly and accurately as I could.
Burned off a bunch of Ha data too but my reducer wasent set rite so all junk,
I will be adding Ha every session now or attempting to do so for a series of sessions.
Well thats it, and a bit more...
Wishing you clear skies with your active Sun and an awesome Weekend Everyone Indeed !

Nicely done Aaron despite your conditions! Mike's right; lots to see now. Unfortunately, all I see now is clouds. As an added bonus, it was hailing an hour ago...
Best of luck!

Cloud all day here though the wind is let up, if I were imaging outdoors it would have blown my scope rite over it was so bad for this session...

Nice work Aaron. I'm afraid to dip my toes into CaK imaging. Yet another money pit. My wife might divorce me!
Thanks Greg,
Your seeing though it appears would tolorate it at times I think, you are rite in that its expensive indeed ..
But if you do get into it with the 152 I'd be a fan for sure.

I've resisted even researching what it would take. Maybe you can PM me some details on your setup? I don't want to hijack your thread here.
Not saying it will happen any time soon, maybe down the road after I get the observatory fully automated.
I've also been looking at the LACERTA or Baader Hershel wedge as I hear that is the best for imaging. Even better than my Bader ASTF solar film.
