I hauled out the 1970s vintage Celestron C90 telephoto lens this morning, attached my AstroZap Baader film solar filter, and my Canon EOS 7D to quickly image Sun. I’m hoping to be able to use the compact mirror lens for quick shots such as this and for images of the Moon; trials have thus far met with mixed results. It’s a cool old lens but not as good as other gear in my current collection. The setup was mounted on a simple photographic tripod and, astro-folk will note, Sun’s orientation here is cockeyed. Once the observatory is set up and a mounted telescope put into use, we expect to see improved resolution/magnification, and won’t have to struggle with gear too heavy for the tripod! There’s a smattering of sunspots to be seen in this image along with a few other, more subtle features in the solar photosphere. Clouds rolled in soon after this image was made.
