The BGO robot imaged epsilon Lyrae for me. A multi-star system typically referred to as the Double-Double. This image is centred on GSC 03122 01380.
Luminance only, 5 seconds subexposures, 20 stacked shots. FITS Liberator, GIMP. North is up; east is left.
The Double-Double is well known for its 4 stars but it is actually a 9-star system. I wanted to view/image this region again so to tag the H star (aka SHJ 277). I had not spotted it on the evening of 8 Jun. SkyTools 3 Pro showed H was almost due north of G. In the image, it is obvious. It is the same brightness has G, arguably brighter. Is it a variable?
