Stephenson 1 is a loose open cluster in Lyra centered around the wide double star Delta Lyrae which consists of Delta 1, the blue main sequence star of spectral type B2.5V and Delta 2, the variable Red Giant. It has been debated whether or not this star is a true binary (probably no) and whether or not this sparse open cluster is a true cluster (probably yes).
This was from only 1.5 hours total exposure as I was once again thwarted by the Windows Automatic Update demon which I thought I had disabled. Processed without flats because I didn't have the heart to take them at daybreak having awakened to a shutdown laptop. Its also my first foray back into short focal length imaging in nearly two years. Couldn't find any interesting short FL targets yet above my horizon by 10 PM. Anybody have any early season unique targets to recommend?
Thanks for looking,
