Nikon D5300 attached to cassegrain focus of Celestron C5 on Sky Watcher Star Adventurer equatorial mount
A relatively small but complex sunspot group. I matched the orientation to the web-based Solar Dynamics Observatory format. This is a 1/640s exposure at the f/10 focus with a Nikon D5300 at 400 ISO sensitivity, taken with a film of solar filter material over the front corrector plate.
