At last, after months of gremlin battles we finally achieved first light for the RiDK 16″ scope! For details on the battle itself you can read the blow by blow in this page. This is a 10 minute guided luminance image of IC 5146, the “cocoon” nebula, a combination emission and dark nebula 4000 LY away in the constellation Cygnus. I picked this object mainly because there are a good number of stars and it is well positioned high in the sky at this time of year. Seeing was a marginal average and what I am discovering is that imaging at this focal length of 2800mm is not going to be easy. I am very satisfied with the star images. They are as advertised, crisp and round throughout the field and no flattener is required. OK so I guess you can get what you pay for sometimes!
Thanks for reading!
