NGC 7000 the North American Nebula in the constellation Cygnus. This nebula is next to the star Deneb which is the tail star of the constellation Cygnus, the Swan. Next to the North American Nebula is the Pelican Nebula (IC5067). NGC 7000 the North American Nebula is very large and visible with the naked eye from a Dark Sky site. It is 1600 Light Years distant, 120 x 100 arcminutes, roughly 4 times the size of the full moon.
IC 5067, the Pelican Nebula, 60 x 50 arcminutes, 1,800 light years distant. This image was captures on film, while the camera was manually guided through a 78mm diameter (3″) telescope using an illuminated cross-hair eyepiece.
Protostar forming in IC 5067, was observed by Jerry Oltion in a 96″ telescope. Jerry conveyed the location in IC 5067. I was able to locate and capture it with a 5.5″ refractor and st10xme CCD camera using a 9nm Ha filter on 8/17/2009 from a Dark Sky site in Oregon. Above and below is a crop of the star form area.

Helix Nebula NGC 7293, a planetary nebula in the constellation Aquarius, 714 Light years away. Discovered by Karl Ludwig in 1824. The helix Nebula formed when an intermediate low-mass star sheds it’s outer layers, leaving a remnant stellar core which will become a White Dwarf star. Helix is 25 arcminutes in diameter, the outer layer is estimated to have formed 6,500 years ago, while the inner region 12,000 years ago.
This image was taken with a 5.5 inch Tech Engineering refractor on an Astro-Physics 1200 mount from a remote Dark Sky Site. All the equipment had to be setup and calibrated for that location.
An SBIG (Diffraction Limited) NABG CCD Camera, color filter-wheel (CFW8a) using Astro-Don Generation 1 true balance Luminance, Red, Green & Blue filters were used to capture the light channels which were combined to form a color image.

Markarian’s Chain of Galaxies part of the Virgo Cluster, form a smooth curve and is named after the American Astrophysicist Benjamin Markarian. He discovered the common motion of the members in the 1960’s. Charles Messier discover M84 (NGC 4374) & M86 (NGC 4406) in 1781, both of which are elliptical or lenticular type galaxies. M84 at magnitude 10 (60 Mly) and M86 at 8.9 (52 Mly). The main galaxies include M84 (NGC 4374), M86 (NGC 4406), NGC 4477, NGC 4473, NGC 4461, NGC 4458, NGC 4438 and NGC 4435
The upper left Super Giant Elliptical Galaxy is M87, on of the most massive galaxies of the local group. It has approximate 12,000 globular clusters compared to our Milky Way’s 150-200.
Markarian’s Chain of Galaxies is a delight to view in larger instruments. Using telescope of 14 inches or more in aperture are really satisfying. Use a wide angle eyepiece of 26-50mm focal length to get the full impression of this galactic Cluster.
Early Spring is the best tome to view the Constellation Virgo, The Virgo Galaxy Cluster and Markarian’s Chain of Galaxies.
