This is a closeup of a famous nebular formation in IC410 in the constellation Auriga. The whole area is filled with glowing hydrogen, but the two brightest parts of the area are shown here, the two tadpoles. These are caused by energy rushing up against clumps of gas; the collision makes the gas glow. This is the highest resolution image of the area I've ever taken. Specifically, I never saw that the second (lower) star of the two in the hood on the right is actually a double star. Probably most telescopes would show it visually at high magnification, but in a long exposure, only a very long focal length and quite good seeing would show the star's double nature. I was happy to see it. This is just 5x600" with the CFF290 Classical Cassegrain through the SXVF-H9 at f/7.93.
