Description

Sharpless 2-240 (Simeis 147), also known as the Spaghetti Nebula. This was a test run for a number of changes, including to see how well the corners held up with the full-frame ASI6200 on the RedCat 51, using Remote Desktop running on a Chromebook to remote in to the imaging computer over WiFi, and the new multi-star guiding in the PHD2 dev release. This is H-a only, there was a nearly 50% moon nearby, so have to go back and grab RGB and maybe Oiii at a later date. Background was noisier than I would have liked, will probably bump up the exposure to 15 min for the next run. It looks like I have a bit of sensor tilt from left to right, left side stars look out a bit.
