Sun 9th March
A new filter tilter now allows further fine tuning of the CaK system...
Just need some decent spells of sunshine to be able to experiment with this a bit more, the setup has promise!

Calcium Saturday 24th February
The weather forecast for saturday had steadily got better as last week went on, but the weather man in me was actually slightly more optimistic for something better still. Turns out I was right, I woke to a clear, frosty and icey morning with nice blue skies. Seeing was forecast to be about 1.2" first thing, slowly worsening to 1.6" by afternoon. I'd already decided with the good transparency the day offered that I was going to image in CaK, and with the seeing looking like what was predicted I decided 80mm was the aperture I was working at for the closeups.

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!
