A closeup of the new active regions in CaK, hopefully it will develop a little more.  Taken with the ED60 with 'new' Baader Blue ERF, homebrew CaK filter and PGR Blackfly IMX249 at 1900mm focal length.

CaK Full Disk July 18th

Transparency wasn't great when I took this image, but the PGR Blackfly has low noise when using gain so it is easy to compensate for.  Not a lot going on, but at least the disk isn't blank!  Taken with the 40mm at 650mm focal length with the home brew CaK filter.

The PGR Blackfly GigE IMX249 allows these great closeups in CaK using the ED60 at 1900mm focal length showing oodles of detail, especially when you click on the image to view it in full size.

There is a lot of plage activity again on the sun as a new set of active regions rounded the limb this weekend.  Taken with the 40mm scope at 650mm focal length with the homebrew CaK filter and the PGR Blackfly GigE IMX249 camera.
