Nearly missed my two hour slot for capturing the sun today. The disk was actually skimming the top of my neighbours conservatory roof when the last one was taken! Taken at 11.45UT. CaK B1200 100mm/Vixen 115

Sunspots and Snow Showers – 20-12-09

December 20, 2009 Leave a comment

Managed to get a view at 10.50 UT between heavy snow flurries. Seeing was typically awful for this time of year with a boiling surface and limb. I tried white light but conditions were too poor to resolve much. Cak imaging was altogether different though with plenty of detail popping out in the spots – narrowband is definitely better than white light in poor conditions. There are three areas of activity with 11035 right on the limb now and 11036 (?) showing a group of small pores, plus a smaller area of brightness between the two main AR’s. Ha PST/Cak B1200 diagonal/Vixen 115 at 100mm.

Holidays and Sunspots !!!! 18-12-09

December 18, 2009 Leave a comment

What a great combination 🙂  Haven’t done any solar imaging since the 26th September so it was great to have the time for a good session today with plenty of activity on the surface. These were taken 11.05 UT – Ha PST, CAK B1200/Vixen 115. Atmosphere was very jittery so nothing is particularly sharp and Newtons Rings showed up with the 2.5x televue barlow (Ha closeup view) as it wasn’t quite straight in the optical path due to the rubbish plastic screw on the PST. Nice to be out basking in the (very cold) sunshine.
