Fantastic, Dave! A better image of M81 than mine which took 11 hours. Similar equipment, similar exposures but the galaxy was 12 degrees higher above your horizon due to our latitude differences. My star colors are washed out whereas yours are colorful. Your scope appears to focus blue better than mine. Another difference are your light-pollution fighting filters. More than all of these things the difference is *you*. You have mastered APP. I have little interest in post-processing.
