Fig. 1

MIPS infrared calibrated images of comet 8P/Tuttle taken on 22 June 2008 (24 μm on the left, 70 μm on the right). The images are displayed with a logarithmic stretch. The 24 μm image has a size of 176 × 194 pixels with a projected pixel size of about 2450 km. The yellow arrows indicate the direction to the Sun (⊙), celestial North (N), and the velocity vector (V). The 70 μm image has a size of 46 × 95 pixels with a projected pixel size of about 3840 km. The coma, dust tail, and first Airy ring are visible in the 24 μm image. The 70 μm image is extremely noisy and unsuitable for nucleus extraction (see text for detail).
