Weekend observing at the Fairwood Observatory
Gaynor Thomas and Steve Wainwright made a quick visit to the Fairwood Observatory on Sunday afternoon.
They observed the Sun in White light with an 80mm refractor fitted with a Thousand Oaks Glass solar filter, Hydrogen alpha light with a H-alpha PST, and Calcium K-line light with a Ca K-line PST via a DMK camera.
3000 frames were captured at 60fps in batches of 1000, processed in Registax and then in the Gimp.

They observed the Sun in White light with an 80mm refractor fitted with a Thousand Oaks Glass solar filter, Hydrogen alpha light with a H-alpha PST, and Calcium K-line light with a Ca K-line PST via a DMK camera.
The newly forming sunspot had already dissipated by the time the observing began and there was nothing of interest in White light or calcium K-line light.
Nevertheless there was considerable interest in H-alpha light with some areas of plage and some magnificent filaments with small prominences.

In the evening, Keith Davies, Gaynor and Steve did some DSLR imaging with 80mm Apochromatic refractors on the new EQ3-2 mount, and Gaynor's Nextstar 8SE
Nikon, Pentax and Canon DSLRs were used. Here are some of the results obtained:
