Figure 1 - The unusual galaxy M82 is much in the news these days because of the discovery of a new Type 1a supernova. This image from Eric Benson shows the dynamic structure of the galaxy, with tendrils of hydrogen gas erupting from the core. M82 lies at a distance of 12.5 Mly in Ursa Major and shares the sky with nearby M81. Eric used a C14 XLT telescope at f/6.1 with an SBIG ST8XME camera. Exposure was 8×600s in each of RGB and 12×1800s in Hα.
