This image of M81 and M82, a pair of galaxies in Ursa Major, was acquired using an SXV-H9 CCD camera mounted on a Tele Vue NP101 Imaging System, a 101mm f/5.4 apochromatic refractor specifically optimized for CCD imaging. A Tele Vue 0.8x Focal Reducer was also used. This image is a stack of 8 eight-minute exposures that were calibrated, defect-corrected and stacked using AIP4Win Version 2. This image has been cropped down from its original size of 1392x1040.
