CaK Proms 16th December
The custom CaK filter is pretty decent at bringing out proms if the sky is transparent enough coupled with a bit of post processing.

Saturday Sunshine 9th January
Despite the day starting with a heavy bad of rain for several hours, by lunchtime the sky had transformed to (nearly!) blue skies. It was very windy though and blowing the lids of all my scope cases shut along with nearly blowing the laptop off. I was chasing the sun with the travelling kit through the gaps in the trees on the southern horizon. Seeing was terrible, and kept me busy searching for a focus that wasn't really there to begin with. Still, I managed to get a trio disks.
First up 430nm Gband, taken 50mm f12 with the Zwo18mm
Then CaK, 60mm f10 with the zwo183mm
And finally the Ha full disk, taken with the setup in the picture - DS50, 2x cemax and the zwo183mm...
Despite the awful seeing and low sun, I was glad to get something. Anything at this time of year is a bonus!

Quiet Sun 22nd August
The sun has plenty of activity but is fairly quiet in terms of flare activity and the like. Taken with a pair of Lunt50 etalons on the 60mm f6 scope, a 2x cemax running on a short nosepiece and the zwo183mm camera. The etalons were not playing today getting on band without tilt, I need to look at a way of permanently screwing the etalons onto the scope rather than them being attached to the OTA by means of a cell.

Double DIsks 20th May
Saturday was a nice sunny day, clear blue skies! Alas I didn't have much time so only managed a quick couple of disks. First off the white light, taken with the Skywatcher ED80 at f7.5 with the Lunt Solar wedge, continuum filter and the ZWO183mm. Second up is the CaK disk, taken with the same scope but at 60mm f10, homebrew CaK filter and the zwo183mm again. I love this camera with it's small 2.4um pixels for full disks!

Ha Full Disk 29th April
It's been a while since i've got round to putting up some images here. Full disk taken with the LC50 etalon on the 60mm f6 scope, TZ4, Solar SPectrum 0.3a, 0.65x telecompressor and ZWO183mm with 2x2 binning. Lots of contrast and quite difficult to get even, but slow exposure time means I probaly won't be using it as my regular grab and go gor full disks.

Ha Full Disk 12th March
The weather has been awful of late, so when sunday offered something almost resembling clear (well hazy really!) skies I decided to just get the scope and go fishing for the less hazy breaks. Seeing was awful and are loosing resolution even at the full disk scale, but, it is nice just to be able to see the sun really!
