gorann Posted June 4, 2017 Share Posted June 4, 2017 As @wimvb just said, we are going through the Liverpool Telescope database - a largely unused treasure chest of deep sky data. What else could Swedes do when it is light enough to read a paper outdoors at midnight? Taken together we have done close to 50 images up to now. When I processed this image I had no idea what it was. I found the subs in the data base with the cryptic name "bd65_1637". Only after uploading it on Astrobin, plate solving told me it was NGC 7129. NGC 7129 is a reflection nebula located 3,300 light years away in the constellation Cepheus. A young open cluster is responsible for illuminating the surrounding nebula. A recent survey indicates the cluster contains more than 130 stars less than 1 million years old [all according to Wikipedia] Filters and Exposures used: sdss- r 15 x 90 s Ha 9 x 120 s (stacked 40:60 with sdss-r for red channel) Bessell B 14 x 90 s (blue channel) Bessell V 13 x 90 s (green channel) The scope is a 2 m RC on La Palma Link to comment Share on other sites More sharing options...
