22:00 – 03:24
Tonight was about using both the 150 Esprit from the observatory and the Sky-Watcher 180 Mak outside. I setup before darkness fell and then proceeded to send the 150 Esprit to image M56, one of the Messier objects I had still not imaged. I decided on 120s exposures and in the end took 90 of them, with a handful or so having to deleted due to movement issues, probably when I stood next to the pier.
The dome would not rotate at sidereal tonight. Every time I set it to 1x sidereal it would after a while run away and just keep turning. This meant I had to manually move the dome every 15mins or so during imaging.
With the Sky-Watcher 180 Mak I imaged Saturn. This time I caught it before 3am, but I also managed to work out how to use the ADC and apply colour channel shift before saving the image.
Whilst I had a lot of frames and the colour shift is much better than the other night, the seeing was not as good tonight. The Jet stream is still out of the way, however the air was very turbulent, thus the gap in the ring cannot be seen as well tonight.
