Thumbs up Sunspots 20th May

Finally found some time to get some solar photography practise in before the Transit of Venus in a couple of weeks.

Tested the PST (just visually), need to install capture software on my laptop again and test the DMK again

Also tested the ED80 with a white light solar filter, and my Canon 5D Mark II hooked up.

Trying to focus on the LCD screen of the camera in daylight is reallllly hard, even with Live View. On transit day I'll take my laptop out and feed the live image to the laptop - hopefully it'll be a little easier to turn the focus knob and watch the live view at the same time (I need a motorised focuser on the ED80).

The first image is about 30 images stacked in Registax, I think it was 1/800s exposure @ ISO250.

The second image is a crop of the two big sunspots.

Last 2 are setup images taken with the iPhone.

- Large 1
- Large 2

Gee I was rusty - but it's inspired me to do another session or two before the event.
