Observed the transit of Mercury. That was frustrating at first, because I didn't set the tripod up properly or test focus on something terrestrial or cut my home-made aperture stop properly to size. When I'd done all these things I was rewarded with a fine projection of the Sun, and Mercury sharp and clear, very small. You could see clouds passing over the sun too. First time I've tried projection, I was really pleased with it.

I thought btw that I'd seen Mercury, and a scratch on the eyepiece. But all the pro photos have the 'scratch' too - apparently it's a sunspot group. I've not seen a sunspot before. Bonus!
