Sun in Hydrogen Alpha / CaK
With Coronado 40 / Lunt 60mm CaK

had many hours of clear skies, and I was able to get much better
seeing than the day before. This is apparent in the detail in
the prominences and on the calcium light disk. AR1289 is still
a huge powerhouse of a sunspot, and we look forward in the coming
days to more flare events! |

Certainly AR1287 looks a lot better in CaK

I really like the resolution and image scale
of the Lunt system

If you look at this medium sized spot, it is
cut in two by a light bridge. This rare
phenomenon usually marks the end of a spot
but here the spot has lingered on. Look
very carfully just below the spot and you can
see the white light faclulae mottling. This is
exaclty the same mottling a thousand time
more easily visible in CaK light above.
