A humid night with some cloud and lots of moonlight. Seeing was below average, but I tried a short session.
I decided to try to go after NGC6888 using some tweaks with autoguiding, and an automated
meridian flip!! I am slowly learning my way through the software used with the ASIair, and am getting familiar with its capabilities. I imaged this while planted on the beach near the astro cabin, August 30.
Skysafari: "About 4,700 light years away,
NGC 6888 is formed by a fast stellar wind from the Wolf-Rayet star HD 192163, also known as WR 136. The star is shedding its outer envelope, ejecting the equivalent of the Sun's mass every 10,000 years. This stellar wind is colliding with, and energizing, a slower-moving wind ejected by the star when it became a red giant around 400,000 years ago. "

I'm going to need another couple of hours to pull out more reds in this one... difficult target.
