This week’s image is a superb ultra-deep offering of the Cocoon nebula from fellow PAIG member Harry Page – VERY nice Cocoon Harry!
The Cocoon nebula (IC5146, Caldwell 19) is a small emission nebula in the constellation Cygnus. Why I particularly like this region is the Milky Way background and the long dark trailing nebulosity of Barnard 168. Lying at a distance of 3,300 light years this small nebula only covers 10 x 10 arc minutes, so Harry is working at a longish focal length to get this frame. Details from Harry are:
1) Lum 10 hrs SXVR H35
2) RGB 5Hrs SXVR H35
3) 14″ newt with orion optics corrector
4) Processed in Pixinsight
Thank you for a superb Image of the Week Harry 🙂
