A nice little active region getting closer to the solar limb taken with the Daystar Quark, Skywatcher ED80, Baader Solar Telecompressor and the PGR Blackfly GigE IMX249 camera. Nice detail given the poor seeing conditions that were seen on the morning the picture was taken.
Whether I just got lucky with the seeing with yesterdays Quarks shots I don't know, but I really didn't expect them to turn out at all, and, in fact they turned out to be the best shots of yesterday. Weird, I know! Anyway, this was taken with the ED80, Baader solar telecompressor and the PGR Blackfly GiGE IMX249 camera.
The seeing was awful under the unstable air we have at the moment, and would not allow me to use my usual 1900mm focal length with the 60mm scope, so, had to back off to 1050mm instead. This image taken with the homebrew CaK filter and PGR Blackfly gigE IMX249 camera.

This has to be one of the blankest solar disks i've seen for sometime, not much happening at all on there! A hazy sky resulted in background light levels being a bit higher than I like in the photo, but, given the lack of real solar observing sessions this July i'll go with this image! Taken with the Coronado DS40 at 650mm focal length using a PGR Blackfly GigE IMX249 camera.

This is the only real activity on the sun at the moment, and even these active regions are decaying and not really doing much. This shot was taken with the ED60 at 1900mm focal length with the homebrew CaK filter and the PGR Blackfly GigE IMX249 camera.
Unless something rounds the suns eastern limb in the next couple of days, the suns disk is going to be virtually blank. This shot taken with the 40mm scope at 650mm focal length with the homebrew CaK filter and the PGR Blackfly IMX249 camera.

AR12388 was just sitting right on the limb, and looking at the GONG website could see it was spitting with plasma jets as it retreated out of view. The top image was taken with the Daystar Quark on the Skywatcher ED80, the bottom animation with the Tal100R and Quark, and spans about half an hours worth of time. While there were no great fireworks it certainly crackled away.
This active region was just heading towards the limb along with it's accompanying filaments, alas seeing in the mid afternoon was not great, but inverting the image makes the detail pop out. Taken with the Skywatcher ED80, Daystar Quark and the PGR Blackfly GigE IMX249 camera.
A pair of full disks from Sunday; the first taken with the DS40 at 650mm focal length, and the second taken with the ED80 and Daystar Quark. The image was taken just after midday and the seeing conditions were not conducive to the larger scope as several of the panels are no where near as sharp as I would like, still, presented at this scale the outcome is just about acceptable!
A bit of playing around with yesterdays full disks in CaK, the disk at the top is my regular image - 40mm scope 650mm focal length, the image underneath with the Ed60 at 975mm focal length, a central swathe of the regions of interest. I wondered which would work best; well, to my surprise the smaller scope showed the better clarity. Maybe the seeing wasn't as good with the ED60? I don't know, but for now I think i'll stick with the regular 40mm instrument.

This shot of the active region turned out quite well with plenty of detail. An interesting brightening around the penumbra of the spot too. Taken with the 100mm Tal100R refractor, Daystar Quark and the PGR Blackfly GigE IMX249 camera.
Another one of those shots that just looked a little flat in regular positive view, but, inverting it really gives the surface a sense of relief. Taken with the Tal100R refractor, Daystar Quark, PGR Blackfly GigE IMX249 camera and Baader Solar telecompressor.
Sometimes when the seeing is dawg awful, and the shot you've taken looks like it should be for the recycle bin, applying an invert and a bit of false colour can be all that is needed to perk the shot back up and make it presentable again. This was taken with the 100mm Tal refractor, Daystar Quark, PGR Blackfly IMX249 GigE camera and the Baader solar telecompressor.
A pair of Ha full disks here, both taken with different setups, and both processed quite differently. The top disk was taken with the trusty Coronado DS40 scope, at 650mm focal length with the PGR Blackfly IMX249 GigE camera. This is a positive image with false colour added. The second was taken with the ED80 scope and Daystar Quark at around 1950mm focal length, again with the same camera. This image has been inverted and false colour applied. It is interesting how the different presentations make the different features on the sun stand out more.
This region of our star was looking quite frothy in CaK wavelengths on Saturday, with the ED60 at 1900mm focal length with the PGR Blackfly IMX249 and the homebrew CaK filter.
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.

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.
