My first night with my re-built observatory and a frosty clear sky. Also, my first attempt at the Jellyfish.

The intention was to create a narrow-band false-colour image, but it seems the filter wheel malfunctioned and I ended up with 25 subs all in H-alpha and none in OIII or SII. Hence, the odd combination of exposures. I stacked the best 18 frames anyway to give approx. 2.5 hrs overall light. At least it shows a reasonable amount of detail.
