The sun is very low in the sky for me now as winter approaches, realistically i can only really observe on weekends, and even then I only have a window of a couple of hours in the gaps in between the houses and the trees. This could possibly be one of my last images for the 2010 season? I hope not...
Solar activity has really ramped up this year, and this picture shows it really well. While there might not be a large number of prominences the disk is alive with activity - active regions and their associated sunspots, flaring, filaments, and on the limb even a filaprom. I will try and observe as much as possible through the winter season, and with activity like this the 2012 season can only get better!

Sundays Proms - 18th September
Not the busiest of days for proms, but I do like the 2.5x Televue Powermate for its ability to zoom in on what little is there!

Solartastic Sunday - 18th September
Solar activity is really starting to ramp up now, and the solar disk is starting to come alive with features - spots, active regions, filaments, filaproms, prominences, plage regions - there's plenty to see.
Nows the time if you have a solar telescope to go out and get a view in - you won't be disappointed!
Saturdays Sun - 17th September
After what seems an age without getting any solar viewing in, saturday finally allowed some clear skies. It was worth it! A fantastic sun presented itself!

Flaming Proms! 1st September
Don't usually do too many proms shots, but these were just too photogenic to miss!
Big Purple Sun - 1st September
The sun at CaK wavelengths looks fantastic when there is alot of activity, and today was no exception. Must make a point of taking more of these images!
This was taken with the 70mm frac @ f10, homemade Baader/Coronado hybrid CaK filter and DMK31 camera. This is a result of 6 panes assembled in Imerge.
Spotty Sun - 1st September
This has got to be the spottiest sun i've been able to observe in sometime. This image was taken with the 70mm frac at f12, Lunt Solar Wedge, DMK31 and 705nm TiO filter. Despite the poor seeing conditions - the solar disk was boiling away in the eyepeice, the long wavelength and narrow bandpass of the TiO filter cut through the turbulent atmosphere and the image was rock steady on the laptop screen. The TiO filter is worthy addition to any white light observers arsenal, used with a solar wedge and refractor the views are excellent. The filter can be purchased from Omega Optical via EBay http://www.ebay.co.uk/itm/Optical-Interference-Filter-705BP10-25mm-Infrared-Astro-/150612232231?pt=LH_DefaultDomain_0&hash=item2311304827
