Jetting off to the sun! Flight LS271 Leeds Bradford to Alicante put on a nice transit for me this morning whilst I observed the sun with the Coronado SM90 double stacked with a Daystar Quark. Wish I was flying off to warmer climes like the people in this plane.
First trial today of double stacking the SM90 with my flat 50mm Lunt etalon. It works well even if there is little to see on the Sun at the moment!
Using the Coronado SM90 double stacked with a Daystar Quark to enhance the contrast I zeroed in on the active regions that are passing over the limb. These really have become quite active for solar minimum over the past couple of days, so it was nice to get a view of them before they departed properly.
Less than ideal conditions mean that the disk isn't as sharp as I know it can be, but it has still came out ok. Taken with the 60mm scope at f15 with the homebrew CaK filter and the PGR GH3 ICX814 camera.
There was the smallest of proms on the solar limb on Sunday, with a wispy filaprom associated the smallest of decayed active regions. This is the bounty that solar minimum delivers! Taken with the SM90 double stacked with a Daystar Quark with the FLIR GH3 ICX814 camera.
Zooming in on the region of decaying plage using the 100mm scope somewhere up around 2000mm focal length with the homebrew CaK filter and FLIR CH3 camera. The Airylab SSM was used to only harvest the best frames with the unstable polar maritime airmass that was over the UK this Sunday.
Viewing the sun in Calcium wavelengths showed a number of areas of plage around the solar equator that mark where active regions from previous rotations. These are the remnants of activity from solar cycle 24. Taken with a 60mm scope at f15 with the homebrew CaK filter and a FLIR GH3 ICX814.
