The sky is full of thousands of surprising objects to explore with binocoli or a small telescope. I will highlight an interesting object or a group of objects in this new daily series, dreams of depth. This brings me back to my first days of amateur astronomy, when I had a couple of binoculars, a celeston 8 telescope and a voracious appetite for having explored what was out there.
Starting high in the sky of the northern hemisphere, I will highlight many things in the coming weeks and months. I will start with the molecular cloud of Cepheus, a region rich with some interesting objects on the border of Cefeo and Cassiopeia.
This rich region contains several emission nebulae, hydrogen gase clouds mostly that will form only childhood and a variety of young open stars clusters. A challenge for visual observers, but often photographed, the great emission of Nebula NGC 7822 arches on the region. Just in his south there is a brighter and smaller patches of nebulosity cataloged as a reverse 214, which is also associated with a small open cluster, Berkeley 59. Well south of these objects there is a small nebula circular emission, Sharpless 2–170. These are all rather dark objects, but together they form an unusual region and rarely observed in the northern Milky Way. If you have a chance, take a look at the next darkness, clear and moonless.
