I went to Roan Jase for a night to do some astrophotography with Julien and Jorge. Conditions were really good, though pretty savagely cold in late autumn, 1000m above sea level.

Trying to get an equatorial mount aligned is tricky. It would be easy enough in the northern hemisphere, where there's a nice bright star near the celestial pole to target, but in the south there's no bright pole star and we struggled to get the telescope well aligned. Shining the laser through the guide scope to see where we were pointing was our best technique.

The moon rose a bit after midnight. I took a video when it did, and did some post processing to extract the best images from the video sequence and combine those to make this final image.
