The Iris and Ghost Nebulae
The constellation of Cepheus is full of beautiful dust clouds illuminated by bright stars. The one on the right is the Iris Nebula, or NGC 7023. It is roughly 1300 light years from our own solar system. The one on the left is the Ghost Nebula, or VdB 141.
The image was exposed for a total of 2 hours and 20 minutes with Chroma LRGB filters, a ZWO ASI2600MM camera, Sky-Watcher Esprit 100ED refractor telescope and an APM Riccardi 0.75x focal reducer.
