The galaxy M109 in Ursa Major. This image is a stack of 55 sixty second exposures using a Vixen R200SS 8" f/4 Newtonian with a coma corrector. The image was calibrated, defect corrected, stacked and gradient corrected. This was followed by 5 iterations of Richardson-Lucy deconvolution, then a simple linear stretch was performed, all using AIP4WIN. This image has been resampled down from its original size of 1260x1000.
