My first summer milky way experience of this year is a slightly minor, but amazing diffuse nebula NGC6820 and surrounding area including M27, the famous Dumbbell nebula and very faint sh2-88 and other interesting dark nebulae. Needed some efforts to harmonize these bright and faint objects into one scene. Two panel mosaic, with limited amount of exposure due to moon age. Expects to get more if I get fortunate fine weather before rainy season.
