This image of NGC4559, a spiral galaxy in Coma Berenices, 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 4 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. If you scroll around the full frame view, you will find loads of tiny background galaxies typical of this region of the sky.
