Tried something completely different on sunday - used the 100mm Tal refractor @ f14 with the homemade CaK filter to do a closeup of todays active regions. This scope seems to perform really well at these wavelengths - will have to use it again!
Images of the Sun, our local star, at a range of wavelengths with specialist solar telescopes. Imaging tutorials, solar bits and pieces for sale, talks and outreach with the Charlie Bates Solar Astronomy Project CBSAP.
