Not a very dark sky and bad collimation, but rather good detection capability for a planetary camera! DIY TEC with 3A/12V Peltier + CPU radiator + fan. Celestron 5 (125mm) + focal reducer f/6.3. Acquisitions in 2x2 binning, darks + flats then slight magnification of final image. Little fixed pattern noise, almost concealed in the sky background. The sensor temp was stabilized in minutes. Raw frames showed large but faint extensions of the arms, but I enventually decreased the levels to lower the noise (city lights at some km away + camera noise). This cam has a great imaging potential even in deep sky, at least for relatively contrasted objects.
