AR12139 Ha 13th August

Frustrated by continual passing clouds I decided to just image regardless this afternoon.  While this shot lacks the usual sharpness and contrast that I like it does show AR12139 undergoing a small B class flare.  Taken with the DS40 at 800mm focal length with the DMK31 camera.

Ha Full Disk 13th August

Most definitely a day of cloud dodging today, there are lots of clouds and not many gaps, and to this point have only managed a full disk.  Not much in the way of proms at all today, but this disk itself is looking nice.  Taken with the DS40 at 700mm focal length with the DMK31 camera.

Hydrogen Alpha Full Disk 11th August

Another quick full disk of our sun from the morning of 11th august.  Some nice detail but a few more active regions wouldn't go amiss!  Taken with the DS40 at 700mm focal length with the DMK31 camera.

CaK Full Disk August 11th

The seeing conditions were far from great when I took this image early on monday morning, but atleast the sun was out briefly, for a bit!  The disk is starting to look quiet again compared to how it has been lately.  Taken with the 40mm at 700mm focal length with the DMK31 camera.

AR12135 CaK Wavelength 9th August

Despite it emerging only a few days ago, and containing 2 large sunspots, AR12135 is already starting to decay and shows no signs of an up tick in activity.  There is a distinct lack of plage around it as can be seen in this image, compared to the amount of plage that there was around some of the active regions in the last week or so, a shame really!  This image was taken with the 40mm scope at 925mm focal length with the DMK31 camera and the homebrew CaK filter.  

Western Limb CaK 9th August

All the activity that has been dominating the Earth ward face of our sun for the last week is now marching ever closer to passing over the western limb.  This image was taken with the 40mm scope at 925mm focal length with the DMK31 camera.

CaK Full Disk 9th August

The sky transparency was great first thing on saturday morning, skies were about as blue as they get in the UK with no haze or high cloud at all.  This has the result of making the calcium images that bit more contrasty, which is always a good thing!  I would love to be able to take some images with the scope from the top of a 3000m+ mountain peak.  This shot was with the 40mm scope at 700mm focal length with the DMK31 camera.
