AR12152 is by far the busiest and most active of this trio of active regions that are heading towards the limb in this image, and is infact undergoing a minor c-class flare. Taken with the DS40 at 925mm focal length with the DMK31 camera.
There seems to be alot of filaments visible on our star at the moment, here is another towards the eastern limb that I took today with the DS40 at 925mm focal length with the DMK31 camera.
I managed to get a moment of good seeing with this image in otherwise poor conditions of this train of active regions all heading towards the suns western limb. AR12152 which is closest towards the lefthand edge of the image was showing some minor c-class flaring at the time this was took with the 40mm scope at 700mm focal length with the DMK31 camera.
While it looks ok presented at this scale the seeing was very ropey when I took this image, and viewed full size soon breaks down. Shot with the 40mm scope at 700mm focal length with the DMK31 camera and homebrew CaK filter.
I took a number of video files to get this image on sunday afternoon as the seeing conditions were not great and I was pushing it using 80mm of aperture and 1750mm of focal length with the DMK31 camera, but, the whole principle of lucky imaging is that if you take enough images one of them will always be the best and will hopefully be acceptable. I like the detail recorded in the penumbra of the main spot and the thin light bridge that crosses the umbra.
This trio of spots get closer to the suns limb in this image taken with the 80mm CaK scope at 1000mm focal length with the homebrew CaK filter and the DMK31 camera.
A little late getting this up here, but here's the CaK full disk from sunday 31st august, taken with the 40mm scope at 700mm fl with the DMK31 camera and homebrew CaK filter.
