Ad Astra Observatory

In retrospect, I probably should have shot RGB from the dark sky site and left Ha for the backyard.
In addition, it was very windy, so I probably should have dumped Cassie in favor of Pumpkin for the night.

Having said that, I got a little over an hour of useable data (four 20m subframes) from NGC6888 tonight.

The guiding was all over the place in the wind, but the RMS was still down in the 1″ range. It’s just that Cassie shoots at 0.6″/px.
