M31 - 10/08/2010 - Samsung SDC-435 & 55mm CCTV lens, 8 seconds
One of my favorite 'Deep Sky' magazines was the Fall 1984 issue with a detailed article by Brian Skiff on observing the
Great Andromeda Galaxy's internal open and globular clusters and M31's attendant satellite galaxies. (see page 8).
I've held on to this issue over the years, wanting someday to do an observing project based on it.
Then very recently, 'Sky and Telescope' came out with several interesting articles on similar topics:
November 2013 issue - "Exploring Messier 31" by Alan Whitman, and
December 2013 issue - "Exploring the Triangulum Galaxy" by Ted Forte, and "Local Group Dwarf Galaxies" by Sue French.
Over the New Year, I sat down and compared the finder charts of these very fine articles with what I've video-captured.
I was able to identify a number of extra-galactic globular clusters and H-II regions in M31 & M33, along with having several
additional Local Group members video-imaged.
Thus, this page,,,,, I invite you to sit back and enjoy my images and additional information perused from the web:
From Wikipedia: "The Local Group":
is the group of galaxies that includes the Milky Way among others. It comprises more than 54 galaxies, counting dwarf galaxies.
The two most massive members of the group are Milky Way and Andromeda Galaxy. These two spiral galaxies each have a system of satellite galaxies.
Milky Way's satellite system (see 'Near' chart below) consists of Sagittarius Dwarf Galaxy, Large Magellanic Cloud, Small Magellanic Cloud,
Canis Major Dwarf, Ursa Minor Dwarf, Draco Dwarf, Carina Dwarf, Sextans Dwarf, Sculptor Dwarf, Fornax Dwarf, Leo I, Leo II, and Ursa Major I Dwarf and the Ursa Major II Dwarf.
Local Group - Near
Chart by Richard Powell
Andromeda's satellite system consists of M32, M110, NGC 147, NGC 185, And I, And II, And III, And IV, And V,
Pegasus dSph (aka And VI), Cassiopeia Dwarf (aka And VII), And VIII, And IX, And X, And XI, And XII, And XIII, And XIV, And XV, And XVI, And XVII, And XVIII, And XIX, and And XX.
The Triangulum Galaxy, the third largest and only unbarred spiral galaxy in the Local Group.
The other members of the group include IC 10, Leo A, Cetus Dwarf, Pegasus Dwarf Irregular, Aquarius Dwarf, and the Sagittarius Dwarf Irregular.
(see the complete list of galaxies below)

Below is my personal observation list of the 'Local Group' galaxies.
I currently have observed 47 galaxy members visible from my Pittsburgh, PA latitude of around +40.
