DP Review looks at the Stellina smart telescope, an all-in-one “observation station” that serves as telescope (an 80mm ƒ/5 apo refractor), digital camera and self-aligning mount. No eyepieces, just a camera, which can stack multiple exposures to achieve something better than a small scope on a small mount could otherwise achieve. All of these things were available when I was messing around with telescopes a decade or so ago, but not in a single, integrated unit. It took work to achieve results like this; now it takes … $4,000. Ow.
So I mentioned that I might try to get a photo of the solar eclipse, weather permitting? In the end, weather permitted — in fact, everything that could have prevented us from observing or photographing the eclipse failed to do so: clouds were intermittent until after the maximum, the tall trees around our house didn’t block our view, and we were even able to find all the gear we needed in time (some hadn’t been unpacked yet).
I used my usual method for photographing the sun: a digital SLR connected to my 5-inch Schmidt-Cassegrain telescope at prime focus, using a visual solar filter. It turned out well: despite the heat (atmospheric shimmer, you see), the filter (Mylar) and the need to focus manually, I managed more than a few clear shots. Above is a shot from the eclipse’s maximum extent (it was a partial eclipse here). I’ve uploaded a few other photos here.
You know, I think this is the first time I’ve done any solar observing or photography in more than five years. I’m glad I found an excuse to do it again.
As hobbies go, astrophotography has murderously high barriers to entry in terms of equipment costs and skill, and the money and time required to acquire each. Fortunately there’s an exception. Taking pictures of the Moon requires neither specialized equipment or skill: my first photo of the Moon was taken with an entry-level digital SLR and a telephoto zoom lens, and people have used smartphones to take decent photos of the Moon through the eyepiece of a telescope.
From that first shot I graduated to prime focus lunar photography, using adapters to connect my SLR to a telescope, making that telescope essentially a gigantic telephoto lens. Here’s an album of those prime focus photos.
But those aren’t the only ways to shoot the Moon, as Nicolas Dupont-Bloch demonstrates in his magisterial new book out this week from Cambridge University Press, which is coincidentally called Shoot the Moon: A Complete Guide to Lunar Imaging.
Let me say at the outset that beginners should stay as far away from this book as possible (they should start with the advice in The Backyard Astronomer’s Guide). This is a comprehensive reference that covers every available way for amateurs to capture lunar imagery with their own equipment, and it does so in a systematic fashion. In method it’s not at all dissimilar from Michael Covington’s Digital SLR Astrophotography (from the same publisher), but for some reason I found the Covington easier to follow than the Dupont-Bloch.
