Nebulae in Cygnus, C19 and C27
Nebulae in Cygnus, C19 and C27 8th and 9th June 2024. Moving on from small or very distant galaxies, I turned to objects within our own Milky Way galaxy. These are both nebula in the constellation of Cygnus, so looking along the plane of the milky way. So, both images contain a very rich star field. The first is Caldwell 19, aka the Cocoon Nebula, a combination of emission/reflection nebula. Figures I have seen suggest the nebula is a mere 3200 light years distant, with a diameter of around 15 light years. From my image, the bright part for the nebula would be less than 10 light years across at that distance The second is Caldwell 27, aka the Crescent nebula (or even the Ear nebula) an emission nebula about 5000 light years away, which will the order of 30 light years across.
