A Wide Field Webcam Image of the Sun 16/05/04 - Maarten de Vries

This is still image from a video of a spotty Sun taken on 16 May 2004. It was an image from a series of test images using an old discarded webcam. The webcam was going to be used for the Transit of Venus, but due to cloud it was never deployed. The resolution of the image is not great, but the sunspots are textbook with a dark centre (umbra) surrounded by the lighter penumbra. Around the sunspot at the very bottom limb a lighter area can be seen. I like this image because it very much shows the scale of things on the sun. I used a very old RGB type webcam with a Belkin USB video bus, version I. It was fitted to my Helios Startravel 102, with Baader Solar Filter, and stopped down to f22. Maarten
