Description

NGC6885 is a beautiful group of stars in Vulpecula. The image is dominated for the coloured stars Vul 18, Vul 19 y Vul 20. There is a difficult controversy about the veracity of the Herschel original descriptions of NGC6885 (diameter 20') and NGC6882 (diameter 8'). I only can localize a cluster in the center of the image, with a diameter of 22' around the blue star 20 Vul. The FWHM was good, but I've pre-processed the shoots with drizzle and the comparison of the results is favorable to the technique. I've taken the shoots in two nights: 09/23/2017 (30 X 120") and 24/09/2017 (30 X 180").
