Description

Here is what my new rig with two Esprits collected yesterday night. The Esprit 150 connected to ASI071MCpro for RGB and the Esprit 100 connected to ASI1600MMpro for Ha. 50x5min RGB and 53x5min Ha. Dark night but but progressive deterioration in seeing (mist) that finally stopped me around midnight. Struggled more than usual with processing but it ended in a desent image I think (mostly done in PS with stacking and a bit of deconvolution done in PI). Ha mainly put into the red channel (as Lighten in PS) and a bit into lum.

I just learned that what may or may not be a planetary nebula above is Sh2-116. Here is some info on Sh2-115 from an APOD text: Sharpless 115 stands just north and west of Deneb, the alpha star of Cygnus. Noted in the in the 1959 catalog by Stewart Sharpless (as Sh2-115) the faint but lovely emission nebula lies along the edge of one of the outer Milky Way's giant molecular clouds, about 7,500 light-years away. The nebular glow is powered by hot stars in star cluster Berkeley 90. The cluster stars are likely only 100 million years old or so and are still embedded in Sharpless 115. But the stars' strong winds and radiation have cleared away much of their dusty, natal cloud.
