Another clear day again this sunday, albeit with a bit of high cloud that made for interesting results when I applied the flat to the image giving an uneven frame. However this has been removed as much as possible in post processing... Lots of lovely detail visible today - great filaments! These seem aplenty on the solar disk of late...

Ha Full Disk - 14th January
Wintertime high pressure is sat squarely over the UK at the moment, and with it comes deep blue skies and cold temperatures. This is great for solar observing, however on my local horizon the sun only gets about 6 or 7 degrees altitude above it - the downside of this is poor seeing, this is most notable in solar images on the limb. which appears to dance and wave in the atmospheric instability. From an imaging point of view this renders (at this resolution!) the spicules and proms on the limb invisible when doing a one shot. However I really took my time in getting a good flat and this has paid dividends in eeking out as much disk detail as possible. Taken with the DS40 @ f21, DMK31.

Proms! 7th January 2012
Some of the best proms i've seen for a while were visible this morning. This was taken with the DS40 @ f26, DMK31. Actually very good seeing for such a low altitude sun...
Filaprom - 7th January 2012
One of the best filaproms i've seen for a while! Taken with DS40, 2.5x powermate - f26 DMK31.
Hydrogen Alpha Full Disk - 7th Janury 2012
An unexpected blue sky this morning allowed me to get some imaging in: absolutely loads going on! Filaproms, proms, filaments and flares! Slightly overexposed on the flaring regions but atleast this shows up the proms a bit better! Taken with the DS40 @ f21, DMK31.

First Sun of the New Year!
I've really lucky this year to get as many images in as I have, though this has been helped by a neighbour who considerably cut down a tree that had been a blot on my southern horizon. This has given me a daily hour long window in the winter months to observe and image the sun.
As we start in 2012 the sun is showing plenty of activity as we approach solar max (even if it is a weak solar max!). There are filaments galore on todays disk, with the southern hemisphere being dominated by behemoth AR1389.
This is the first shot taken with my recently modded DS40 scope, more details can be found about this on Stephen Ramsdens excellent solar forum...

Late December Sunshine!
With only a few days to go until the solstice I was really surprised to get my last image of 2011 in!
