This little active region as appeared on the limb has developed very rapidly, and at the time of this post has been crackling away with C-class flares and also a small M class flare. Certainly one to keep an eye on in the coming days ahead. This image was taken in poor conditions with variable transparency caused by high clouds, but, given the conditions has come out better than expected. Taken with the 125mm scope at 3.8m focal length with the Baader Solar Telecompressor and the PGR Blackfly gigE IMX249 camera.
Unexpected clearish (read hazy) skies allowed me a brief window in what has been a poor summer of solar with the weather to capture a few shots. The full disk here was taken with the Coronado DS40 at 650mm focal length with the PGR Blackfly IMX249 GigE camera.

The sun seems to be covered in filaments at the moment, and for a change some big proms, even if they were faint. It was a nice looking disk that I was pleased to get a picture of. Taken with the DS40 at 650mm focal length with the PGR Blackfly GigE IMX249 camera.
The seeing didn't really allow the clarity I would have liked with this image, but it was nice to be able to get a shot of it. Taken with the ED60 at 1900mm focal length with the homebrew CaK filter and the PGR Blackfly IMX249 camera.
Seeing and transparency were disappointing on saturday morning despite a forecast of grandeur from the weatherman. This little active region is fairly quiet as it heads towards the limb in this shot taken with the ED60 at 1900mm focal length with the homebrew CaK filter and the PGR Blackfly IMX249 camera.

This really is a large active region, not the biggest we've had this solar cycle but a big one never the less. There was just enough gap in the endless clouds this afternoon to get a capture of this turbulent maelstrom of plasma and magnetism with the 125mm scope with the Daystar Quark, Baader Solar Telecompressor and the PGR Blackfly GigE IMX249 camera. I've included a scale of Earth on the image to show just how large these features on the sun actually are. Here's a black and white version of the active region taken at a similar time:
I was worried with a new huge active region appearing this would destine the British weather to be appalling for weeks, well yesterday I got a brief gap late in the afternoon so decided to get out and observe it. Seeing was all over the place as I was imaging in tight gaps in between bands of clouds. By taking dozens of imaging runs, and then stacking these, I was able to pick the sharpest from that session which is the image above - lucky imaging! The shot was taken with the Skywatcher ED80 refractor, Daystar Quark, Baader Solar Telecompressor giving a 0.75x reduction factor, and the PGR Blackfly GigE IMX249 camera. Stacking done in Autostakkert, with post processing done in IMppG and Photoshop CS6.
A quick look at this active region as it heads towards the suns western limb, taken with the ED80, Daystar Quark, Baader solar telecompressor and the PGR Blackfly IMX249 camera. There was haze appearing when the shot was taken which meant a bit more work in post processing to recover some of the details and contrast.
The new active region is a monster when seen in context with the rest of the suns disk like this, activity seems to be on the rise with potentially more active regions on their way around the eastern limb. I took the shot above with the 40mm at 650mm fl, and the shot below with the 60mm at 1050mm focal length. Both with the homebrew CaK filter and the PGR Blackfly GigE IMX249 camera.
It's about time we had a decent active region, and this one has developed nicely over the past couple of days. The clouds cleared for long enough to get a view of it, but poor seeing didn't help detail levels. Taken with the ED60 at 1900mm focal length with the homebrew CaK filter and the PGR Blackfly IMX249 camera. Hoping conditions are slightly better today for another view as this active region has now started flaring.

The proms were just about visible in this CaK full disk from the 2nd august, seeing wasn't great at all, and even with the 40mm scope at 650mm focal length the resulting image is not as sharp as I know it can be. Still, better than no sun at all!
Sunday offered challenging conditions to try and capture the sun, with despite warm temperatures lots of passing clouds and few decent gaps. This image was taken with the DS40 at 650mm focal length with the PGR Blackfly GigE IMX249 camera.

The 125mm scope did not like the seeing conditions and this image is a bit soft viewed at native size, but i'm really pleased with the image scale I get with it and the Daystar Quark in conjunction with the PGR Blackfly IMX249 camera.

The dark snaking filaments are cooler clouds of plasma held aloft the surface of the sun by intense magnetic field lines. This image was taken with the 125mm scope, Daystar Quark, Baader solar telecompressor and the PGR Blackfly GigE IMX249 camera.
I finally got round to finishing a mod off I started some time ago, sorting out the objective on my Meade 127mm refractor. I have it stopped down to 125mm and is sporting a Beloptik Tri-band ERF internally to cut back energy levels so I can use it with the Daystar Quark safely. These are the first images from it and have to say i'm pretty pleased. I have a nice range of focal lengths and apertures I can use now depending on seeing to go all the way from full disk to hi-res closeups like this. The Baader solar telecompressor was used to reduce the image scale back a bit. This is slightly off band but still a nice result I think.
