Cycle 25 Plage in CaK - 30th August

A close up of the region of cycle 25 plage taken with the 100mm Tal Refractor at f28, using the Airylab telecentric, homebrew CaK filter and the FLIR IMX174 camera.  The seeing was just on the limit for the aperture used and I had to take a lot of frames to get a usable image from them out of the other end.

CaK Full Disk 30th August

The sun is quiet at the moment apart from a region of cycle 25 plage in the northern hemisphere.  Scope used was 60mm aperture with f16 at both the filter and also the camera.

Proms! 30th August

Taken using the 118mm refractor at f28 using the Daystar Quark and the PGR FLIR IMX 174 camera.  There were lots of nice prominences visible on the sun on Sunday!

A Trio of Active Regions 3rd August

Cycle 25 really is coming alive and for the first time in years we have three active regions lined up in a row.  It was nice to see so much bright plage on what has been a quiet sun for too long.  Taken with the Coronado SM90 double stacked with the Daystar Quark, Airylab 2.7x telecentric and the FLIR Grasshopper IMX174 camera.

AR12769 & AR12770 in Ha With the Airylab HaT 3rd August

I was pleased to be able to frame both active regions in one shot with this image taken earlier this morning.  The new active region on the limb was showing one spot when imaged, however looking later in the day there is actually a pair of decent sized spots.  The new active region appears to be quite dynamic and there was surging going on when the area was imaged.  Taken with the 8" Airylab HaT, 2.7x Airylab telecentric, Daystar Quark and FLIR IMX174 camera.  Pleased with how this image came out as my seeing doesn't usually support these larger apertures.

AR12768 in Ha with the HaT - 3rd August

The seeing was obliging first thing this morning and so I decided to give the 8" Airylab HaT a run to see what I could get on the cycle 25 activity we have at the moment.  Conditions were just about holding up using this aperture and I was using.  The Daystar Quark and an IMX174 camera was used to image.  I was surprised at how much bright plage there still was in this quite rapidly decaying active region.

Ha Full Disk 3rd August

The sun really is starting to pick up in terms of activity as can be seen on todays full disk image.  Taken with a Lunt 50mm etalon on a 60mm f6 scope and double stacked with the Daystar Quark.
