Sunday Sun 11th April 2021
Another beautiful day with an almost cloudless start, so another opportunity for solar imaging in Ha and Ca II K. With half decent seeing (for a nice change) I even tried a close up view of the bright plage area towards the east.
Hydrogen Alpha FDs in Mono and Colour:
Lunt 60
Basler acA2440-75 um
1.5X Barlow
2 Pane Mosaic

Calcium II K FDs in mono and colour:
Altair Astro Lightwave 72mm
Lunt B1800 CaK module (modified)

1.5X Barlow

Seeing that the conditions were pretty good, I switched over to my Tecnosky 125 mm for a closer view of the bright plage region.

Basler acA2440-75um camera
2.5x PM
The images have been cropped a little.

Interestingly there are some bright points in the core of this region of magnetic froth, presumably indicating an increasing concentration of magnetic flux in these regions. There's also a little dark core. Maybe sunspot genesis......?

Thanks for looking.

Perfect images of Ha and CaK, Stu!
Sense of 3d effect when look on Ha image.

Stuart,
It looks like you have captured a couple of pores in your excellent CaK closups. Your Ha and Cak full discs look great too!

Super shots Stu! If you compare those bright points in CaK you find they are contemporaneous with small pores in WL.
