  Messier Object 108
According to Charles Messier's hand-written preliminary and unpublished version of his catalog, M108, similar to M109, was discovered by Pierre Méchain shortly after M97 (which he had found February 16, 1781): Méchain discovered M108 3 days after M97 on February 19, 1781, and M109 on March 12, 1781.
Both objects were apparently also observed by Charles Messier when he measured the position of M97 (March 24, 1781), but apparently he didn't find occasion to obtain positions for these objects at that time.
Messier listed this object, M108, under number "98" in his preliminary manuscript version of his catalog, without giving a position.

Messier was interested in finding comets, and this list catalogs objects that proved not to be comets.
Due to Messier recording it at a location 4 degrees away, it was considered "missing" for long time until his descriptions were paired up with the object NGC2548.
Messier discovered M88 in 1781, and described it merely as a "nebula without a star".

The Messier Catalogue was compiled by Charles Messier in the 1700's as he searched for comets, but in order to understand the catalogue it is important to understand the man behind it.
Charles Messier was born on June 26,1730 in Lorraine, France the tenth of twelve children.
Messier's wife died in 1798 and he was left alone.

 Messier Object 108   (Site not responding. Last check: 2007-10-17)
M108, together with M109 was probably discovered by Pierre Mechain in the same night when he found M97 (February 16, 1781), and observed by Charles Messier when he measured the position of M97 (March 24, 1781).
Messier measured an acurate position at a later time which he added by hand in his personal copy of the catalog.
Color photos show an even more conspicuous appearance of this should-be showpiece, which often appears in wide field and "deep spatial depth" photos together with the Owl nebula M97, which is only about 48' to the SE.

M102 may be a duplication of the Spiral Galaxy M101 (NGC 5457) in Ursa Major, due to an error of either the catalog author Messier, or its `discoverer' Mechain.
M102 may be the Lenticular Galaxy NGC 5866 in Draco, also sometimes called the Spindle Galaxy, as Messier's catalog description indicates, together with the position he added later by hand.
The authors of S.E.D.'s think that there is enough evidence that both Mechain and Messier have probably observed NGC 5866 in context of this catalog entry.

Messier 78 is a very diffuse nebula in Orion, this 8 by 6 arc-minute patch is part of the great Orion complex of nebulosity, however, unlike the Orion nebula (which is glowing gas) this nebula shines by reflecting light from the 10th magnitude star 'HD 38563'.
Messier 82 is an irregular galaxy about 9 by 4 arc-minutes in size and has a visual magnitude of about 8.8.
Messier 108 is seen nearly edge-on, it is of 10th magnitude and has the very elongated size 8 by 1 arc-minutes.

If the night sky were to be thought of in terms of a world map, the 110 Messier objects would be the major metropolitian areas and tourist attractions.
Most astronomy clubs hold special "Messier Marathon" star parties where observers attempt to find all 110 objects (well actually all 108-109 objects since one or two are non-existant*).
In 1995 I successfully viewed 105 of the 108 objects by star-hopping methods at the Orange County Astronomers marathon.

 Review: The Year-Round Messier Marathon Field Guide   (Site not responding. Last check: 2007-10-17)
The independent discovery by a number of people that during a certain period in late March/early April, all 110 Messier objects could be seen during one night when viewed from mid-northern latitudes, gave rise to popular club observing sessions.
The heart of the book is a collection of finder charts of all the Messier objects in roughly the order in which one would try and observe them during a Marathon.
It should be noted that from UK latitudes the full Messier Marathon is not possible, but many observers might like to see how many they can find in a single night.

 The Messier Marathon
Messier Marathon is a term describing the attempt to find as many Messier objects as possible in one night.
Note: Most Messier Marathoners accept NGC 5866 as M102, either in account of historical evidence, or at least as substitute accepted for the Messier Marathon, and thus arrive at actually 110 different objects.
Messier Marathon was invented independently by several North American (including Tom Hoffelder, Tom Reiland and Don Machholz) and perhaps one Spanish amateur astronomers and groups, in the 1970s.

Some of the objects are bright like the Pleiades, while others like M98, M 108, M 109 were dim enough (tenth magnitude) to test the light-gathering capabilities of my 80 mm refractor and observing skills like averted vision.
The Messier list can be completed with modest equipment from suburban sites, and don't forget that the S.A.S. has a wide variety of club scopes available to members that can show you most if not all the Messier objects from your backyard.
The Messier marathon is usually held near the end of March so check the March issue of the Asterisk for the exact date.

Messier Marathon inventor Tom Hoffelder finally managed to hold a 20th anniversary marathon in the night of April 6-7, 1997, from a place near Tulsa, Oklahoma, and logged 101 Messier objects, by chance the same number as in his first marathon 20 years ago.

Messier 81 is a bright, compact spiral galaxy; its two outer, very delicate, arms may be glimpsed in fleeting moments with the 8" scope under extremely dark skies; the ETX 125 fails to show these.
This galaxy in the LX 90 under very, very dark skies can be clearly made out to be pencil-shaped, and edge-on galaxy with a clearly-defined character in medium-high power; the ETX 125 shows it well, but lacks the aperture to clearly show the 7' arc length of this curious object.
Concluding our GO TO TOUR or Ursa Major is the famous planetary nebula (gas cloud shell remnant from a supernova explosion) Messier 97, also known as the "Owl Nebula." It's name comes from two dark ovals equally spaced off-center that resemble the two "fl eyes" of an old hoot owl.

The initial color images of the Messier Objects were obtained with the 24-inch f/5 reflector at the Grasslands Observatory from 1998 to early 2000.
These images are gradually replacing the older AP7 images, because they have a larger field of view, and upgrades to the observatory have permitted longer exposures and better images.
Because the images have the same relative exposures for each object type and the same camera orientation and image size, they can be used to compare one Messier object with another.
