At the 2000 Texas Star Party, the well known visual sadist Larry Mitchell challenged advanced observers to find 25 of 32 difficult objects all with visible ring structures. Here are the images of 30 of the 32, all taken during TSP2000. 286 These images were taken as part of the Astronomical League's Arp Galaxy observing program . See Information for a description of the telescope and camera used for these images. Each image is a four minute exposure.
North is always up and west is right.
For more information on Arp Galaxies check out Caltech's Atlas of Peculiar Galaxies or Dennis Webb's Arp's Catalog of Peculiar Galaxies . The images were taken at the 1998 Texas Star Party near Fort Davis, Texas, the Houston Astronomical Society's observing site near Columbus, Texas, the Star Hill Inn in Sapello, New Mexico, and the Pellerin Observatory in New Ulm, Texas.
