The bright star is the left star in Orion’s belt, Alnitak, Magnitude 1.74 and 817.44 light years away.  Just below Alnitak (ζ Ori) is the Flame Nebula HV 28 (NGC 2024) and to the right is the famous Horsehead nebula. The top bright star Alnilam, is the central belt star of the constellation Orion.The dark dust blocks out light and the resulting silhouette resembles a Horsehead. This nebula is not visible to the naked eye and it takes special filters and a large telescope to discern the Horsehead shape. This nebula was first detected on photographic plates by E. Pickering in 1889. The Horsehead is approximately 1 light year across at a distance of 1200 light years from Earth.

While the Flame Nebula NGC 2024 is 1,500 light years distant.  This nebula is very energetic in ultraviolet light. It knocks away electrons from the great clouds hydrogen gas in the surrounding area

This image was taken through and Orion ED 80mm refractor. This is an inexpensive doublet near APO.  One of the true values available to amateur astronomers today.

Crab Nebula M1 NGC 1952 resides in the constellation of Taurus the Bull. This nebula is the remnant of a supernova of a large star. This explosion was first viewed from Earth on July 4, 1054 by Asian Astronomers. Native American Indian tribes also observed and recorded this event. At magnitude 8.4 and a diameter of only 6 arc minutes (11 light years), it is visible in small telescopes as a fussy irregular object. It is approximately 6,500 light years from Earth, in the Perseus Arm of the Milky Way.

The Dumbbell Nebula M27 NGC6853 resides in the constellation Vulpecula.  It lies just west of Cygnus the Swan, at a distance of 980 light years. The Dumbbell is a remnant of a nova, spotted by Charles Messier in 1764.  The gases of which continue to spread outward from the cataclysmic event. M 27 shines at an overall magnitude of 8.1 and is 15.2′ arc minutes in size.  It is about half the diameter of the moon. It derives its name from the sphere of gas surrounding the small remnant of the central star, forming a “dumbbell type” shape. This object is readily visible in small telescopes and can be seen with binoculars as well.

At a distance of 1,360 light years, the Dumbbell (also called” Apple Core”), because of its brightness and close proximity, it is a nice object to observe in modest sized telescopes.  It is estimated to be 9,800-14,000 years old.

This image was capture using a Celestron C11 f/10 Schmidt Cassegrain (SCT) on a Losmandy C11 Equatorial Mount.

The Ring Nebula M57 / NGC 6720 is located in the constellation Lyra, between the bottom two stars b & y Lyra that form a parallelogram below Vega. M57 the Ring is one of the best known Planetary Nebula in the sky. Distinct gas clouds that form this spectacular ring, were thrown off by the magnitude 15.31 central star. The central star was originally a Red Giant and is near the end of it’s stellar evolution and is forming a white dwarf. It has been expanding for approximately 1600-1840 years.The nebula itself, has only a total brightness of magnitude 9. It is about the same size as Jupiter when viewed through telescope with a size of only 3.8′ arc minutes. It requires 6-8 inch scope to see it as a small smoke ring. To see the central star usually require a 10″ or larger telescope. M57 also know as NGC 6720 is about 2,150 Light Years from Earth.

Charles Messier was searching for comets when he discovered the Ring nebula in January 1779.  It found its way into the Messier’s Catalogue as M 57.  The Messier catalogue lists 109-110 objects readily observed in a good 4″ refractor.

Below is a cropped view of the same image above, clearly showing the central star.  The resolution that modern day CCD imaging can accomplish in small telescopes is amazing.
