< Previous Next >I've been waiting for a long time an opportunity to image this beautiful nebula. Unfortunately freezing temperatures affected my camera battery, which lasted only four ten minute exposures. Framing went a little off also, because I really couldn't see the whole nebula in my laptop display. I need to get back on this and collect good HaRGB data.
