Beginning amateur astronomers soon encounter the term “Messier objects.” They learn that this is a list of objects outside our Solar System that are visible through small telescopes. This list was originally compiled by Charles Messier, in the 18th century, from his observations and those of contributors. The catalog has been updated over time, as recently as the mid-20th century, to 110 objects in total.
We’ve noticed some nice full-color and RGB deep-sky images made by Jerry Macon using our Tele Vue-NP127is telescope. They’re all taken from his private Dark Star Observatory in Taos, New Mexico. His image of the expansive North America Nebula (NGC 7000 – above) displays how the deep red light of Hydrogen-α dominates this emission nebula (an ionized cloud of hydrogen gas about 3° across). A feature of this nebula is the “Cygnus Wall” section at the bottom, that includes “Mexico” and “Central America.” This feature is a dense star-forming region of dust and gas that is often imaged alone without the rest of the nebula.
If you’re suffering from the cold northern winter like we are at Tele Vue headquarters in upstate New York, you’ll instantly be “warmed” by these “hot” solar images made by Jordi Sesé Puértolas from his balcony in Barcelona, Spain. These photos appear to show a blazing inferno on the “surface” of the Sun. However, science tells us this is not fire we are seeing but hot plasma (ionized gas) and gas in the wavelength of Hydrogen-α light.
