Ha Full Disk 21st May

Ha-FD-DS50-2x-cemax-zwo183mm-colour A hugely oversampled disk using the DS50 setup, 2x cemax barlow and the ZWO 183mm camera. The barlow seems to give around 2.5x. The weather was not cooperating and I sat poised for some time at the scope waiting for fleeting gaps that I could grab some frames in, still, glad I did as the forecast is not promising for clear skies in the foreseeable.

CaK Full Disk 19th May

CaK-FD-50mm-f16-zwo183-colour Solar time seems to have been quite limited this year, with it being sunny when i'm at work, and then cloud building up in the evenings. On Thursday I did manage to get a quick full disk in the haze before the clouds finally closed in. Taken with the LZOS 100/800 refractor stopped down to 50mm, the home brew CaK filter and the ZWO 183mm camera, which gives a lovely image scale with this scope.

80% Gibbous Moon 11th May

Got out with the LZOS 100/800 and 183mm camera for the whole disk, the close ups taken with the 2x cemax barlow and the zwo290mm camera.

Crescent Moon 5th May

cresecent-moon-100-f8-183mm-bw First test with the APM 100/800 and a newly acquired ZWO183mm camera. Perfect frame size and perfect pixel size for this scope. I plan to use it for WL and CaK solar, and, fixed noise permitting, with the Coronado DS90. Big images equals big file sizes, so I think the next upgrade will be a new laptop to handle it better.

C-Class Solar Flare in CaK - 30th April

CaK-ani-1024-colour Couldn't believe my luck when I turned my scope onto the sun and there was a c-class flare erupting just off the limb. This animation shows it's development over a period of 19 minutes. Things happen quick on the sun!
