29.5.19

29th May 2019 Solar: Cloud, Prom and Google's illegal storage idiocy.

*

Wednesday. 49/55F Out/In. Opened up at 9.00am with the cloud already becoming a nuisance after an early clear sky. Nothing visible on the disk in white light. Still waiting for a clear view in H-alpha.

I had to close the hatch because I needed to stand just there to use the binoviewers. It is increasingly tempting to move the ladder outside to access the dome via the veranda. But that means making a much better double door with externally accessed security. I put the stairs inside the building to avoid an icy climb in winter. Hindsight is an awful nagger!

9.10 Disk clear in H-a but the large pyramidal prom of yesterday seems to have shrunk. More misshapen now. Tracking has not started automatically nor to clicking "Track" in C-Du-C.

Set up my adjustable height [ironing] observatory chair. I find it is easier on the neck to relax in a chair to tip my head back.

Far too much cloud today! The "Skywatcher" focuser motor paddle is still misbehaving. Continuous rotation after button release. No reverse rotation on the opposite button.

The image was the result of 10% of 500 frames in SharpCap, stacked in Registax 6, with only one wavelet bar and then recoloured and resized 200%  in PhotoFiltre. The Sun's disk was simply "filled" with black. "Atmosphere" using black fill again but with only 10% opacity to gently kill the background glow and improve contrast. The wispy edges of the prom were lost to my clumsy digital image handling.
