I was pleased with these results from the 21st taken with the ED60 and homebrew CaK filter, especially given the low altitude of the sun. The proms were quite bright today too, normally a sign they are quite energetic. I also did an over exposed shot to show them up a bit more:
Both shots taken with the PGR Blackfly GigE IMX249 camera, it's large pixels are great for CaK work like this where I think it excels!

This active region had just rotated into view when I observed the sun on saturday morning, conditions weren't great in the low sun but I was pleased with the result taken with the ED60 at 1900mm fl with the PGR Blackfly GigE IMX249 camera.

It's been 3 weeks since i've been able to observe the sun, fortunately there was plenty to see on the disk, and some nice proms too! The sun is really dropping in altitude now and sits low in the tree tops, so it's a game of waiting for the gaps.

I was really pleased to be able to image this complex active region that rounded the suns eastern limb in the final days of october, the complex string of spots is quite unusual. This shot was taken with the ED60 at 1900mm focal length with the PGR Blackfly gigE IMX249 camera.

This active region is just looking to explode into activity, it was crackling and bubbling away in both Ha and CaK light today. Taken with the ED60 at 1900mm focal length with the homebrew CaK filter and the PGR Blackfly GigE IMX249 camera.
The sun looked serene and smooth in Ha I though today, but in CaK light it looks really quite angry I think, the active regions that are visible are real firecrackers and are likely to send plasma Earth ward in the next couple of days as flaring inevitably happens.

Wow, the sun is getting low in the sky now, but, I supposed it is the 1st November and only 7 weeks till the winter solstice. First time i've been able to observe the sun in what seems like ages today, very autumnal with all the fog, but it did clear long enough for me to get some shots in. First was with the DS40 at 650mm fl with the PGR Blackfly GigE IMX249 camera.
