AR12539 in CaK - 3rd May

Only a couple of very small spots and some pores make up this active region.  Taken with the 100mm Tal100R at 1400mm focal length with the home brew CaK filter and the PGR Chameleon 3 (IMX265) camera.

Spot The Paw Print? AR12535 & AR12536 in CaK - 3rd May

These active regions are quiet but picturesque as they head towards the suns western limb - can you spot the paw print in the spots?  Can't beat a bit of Pareidolia.  Taken with the 100mm Tal 100R refractor at 1400mm focal length with the homebrew CaK filter and the PGR Chameleon 3 (IMX265) camera.

CaK Full Disk 3rd May

Up nice and early this morning for a spot of solar observing before work.  The full disk in CaK always looks nice!  Taken with the 40mm scope at 550mm focal length with the home brew CaK filter and the PGR Chameleon 3 (IMX265).

AR12539 in CaK Light 2nd May

It's nice to see so much activity on the sun at the moment, even if it is only in the solar northern hemisphere.  Another active region can be seen on the eastern limb rotating into view with what would appear to be a couple of small spots in it.  Taken with the 60mm scope at 1050mm focal length with the homebrew CaK filter and the PGR Chameleon 3 (IMX265) camera.

AR12535 in CaK 2nd May

Using the 60mm scope at 1050mm focal length was about all I could push things with the poor seeing, but the end result isn't too bad of these pair of active regions heading towards the suns western limb.  A little bit of flaring in one of the active regions, and in the other the spots take on the appearance of a paw print - Pareidolia!  Taken with the homebrew CaK filter and the PGR Chameleon 3 (IMX265) camera.

CaK Full Disk 2nd May

Transparency was great allowing for a nice fast exposure, which was good as the seeing was awful coupled with the blustery wind.  Still, this image came out looking quite nice in the end.  Taken with the 40mm scope at 550mm focal length with the homebrew CaK filter and the PGR Chameleon 3 (IMX265) camera.

CaK Full Disk and Halos - 1st May


The weather forecast for sunday for me was rain, apart from a glimmer of hope of a bit of sun right around dawn. I decided to get up early and take my chances. The sky wasn't completely clear, and as a result there was a fantastic display of halos: I'm used to the usual 22 degree halo in our frequently milky skies, but today offered a bit more. There is a hint of a Parhelic circle, parhelia (sun dogs), a really bright upper tangent archttp://www.atoptics.co.uk/halo/common.htm but also a plainly visible 46 degree halo, which is an altogether rarer phenomenahttp://www.atoptics.co.uk/halo/46hal.htm , and something i've only seen a couple of times in over 30 years of looking for these things.  Anyhoo, I was supposed to be solar observing, I started off with the CaK full disk, this is all I got as those clouds were thickening all the while. This is all I ended up with in the end...  Taken with the 40mm scope at 550mm focal length with the homebrew CaK filter and the PGR Chameleon 3 (IMX265) camera.
