Originally published 26 July 2010 on the earlier martinpeniak.com site.

Preserved as part of the astronomy and observation thread around cameras, optics, and the sky. The article keeps its period voice, with light formatting cleanup.

Last night we had a glimpse of clear sky, so we tried for the second time some astroimaging with our new scope. Images below show Venus as well as sunspot 1089 through red, green, blue, and infrared/ultraviolet blocking filters. The sunspot is quite large, but X-ray analysis showed little flare activity in the region.
