NIce and clean looking. You make it all sound easy!


The air was actually blue with my language at the beginning of the session when I came out to find that my mount was no longer tracking because of an issue with ports in PHD. I had to manually home everything, reconnect everything, recalibrate guiding, then start the captures from scratch!! Luckily, the sky was actually darker and clearer by then so I just went straight to the 5 minute subs and crossed my fingers :grin:
