Celestron Travel Scope 70 and Nikon D3100
400mm f/5.7 70mm aperture refractor telescope with a Nikon D3100 body which has a 1.5x crop factor, for a 600mm 35mm equivalent focal length. This makes each frame about 3.44 degrees wide, or 6–7 times the angular diameter of the sun, which seems about right based on the photos we got.
The SLR is mounted via a Nikon F-mount to T-mount adapter ring and a Celestron "1.25-inch Camera T-Adapter" telescope tube to T-mount adapter. The telescope won't focus with a camera mounted behind the included 45 degree diagonal, but works fine at all ranges with the T-Adapter coupled directly, as shown.
The solar filter, taped on for security, is metalized film, and came with the telescope in the solar kit version (which B&H miraculously had in stock a week after a total solar eclipse and five days before a transit of Venus). I'm using a Tiltall photographic tripod rather than the lightweight portable tripod that came with the Celestron. The stock tripod is pretty unsteady.
