CaK from 25th (and a WL of AR2976)

[Rob63]

Yesterday (25th) was my first decent length of session with the Lunt B1200 CaK module with the sun at a reasonable altitude.
Seeing was not great with a lot of high haze but there wasn't much in the way of wind or clouds.

I was able to test with various masks 100mm, 75mm and 50mm to figure out what the best option was for my Skywatcher ED120 DS pro (900mm f7.5).
Camera was the ASI290MM (usb3 at around 120fps)
The best by far from my session was 75mm giving f12, this is still a little bit undersampled but looks pretty good to my eyes.
