Solar Photography Practise for the Transit of Venus

With the Transit of Venus only a couple of weeks away, I finally found (or made!) some time to get some solar photography practise in. It’d been a very long time and I was as rusty as my EQ6.

I tested the PST (just visually), but didn’t capture any images with my DMK – I need to install capture software on my laptop again and test capture and processing again.

I also tested the ED80 with a white light solar filter, and my Canon 5D Mark II hooked up. I had reasonable success and am happy with how the image turned out.

The image above is about 30 images stacked in Registax, I think it was 1/800s exposure @ ISO250. Here’s a close-up crop of the Sunspots.

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).

These last 2 images are setup images taken with the iPhone. The first of the ED80 and Canon 5D Mark II setup, and the second of the PST.

Gee I was rusty – but it’s inspired me to do another session or two before the event
