The transit of Mercury happened! Luckily I could escape a little bit early on transit day and set up the telescope to catch us a transit. We see that the gear is a fairly basic set up based on a Sky-Watcher ED80 equipped with a neutral density photographic solar filter from Baader Planetarium and a Canon D600.
In the end I got a little bit sunburned and Skrållan, my then 9-week-old boxer puppy, found a bit of shade by the photo bag.
We saw the whole picture at the top of the page with Mercury to the left and a couple of sunspots in the middle. Below we see two 100% close-up cropped frames to get a better look at the details. The difference between sunspots that are irregular and are surrounded by a lighter penumbra, and the silhouette of Mercury that is perfectly (to the limit of the camera) round and smooth is easy to see.
