Subject:	September Messier Tour

Twelve Month Tour of the Messier Catalog

September Objects

We continue our tour this month with eight more globular clusters, all

are possible in binoculars, and two of these are the finest globulars

which can be seen from northern locations.

Sagittarius is the home of many globular clusters which surround the

center of the Milky Way Galaxy. Seven of the these globulars appear

in the Messier catalog, we will be visiting five of them this month.

When you complete the search for these objects be sure to spend some

time scanning this region with binoculars or a telescope and see what

other sights you can discover. I guarantee you will not be disappointed.

M13

The great globular cluster in Hercules is bright enough to be seen

with naked eye. Binoculars easily show this cluster as a bright fuzzy

ball. M13 is partially resolvable in small aperature telescopes and

becomes a fantastic swarm of tightly packed individual stars through

large scopes.

M92

Another globular cluster in Hercules, M92 is easy to find in

binoculars appearing slightly dimmer and smaller than M13. As with M13

it is partially resolvable in small scopes and is a fine sight in large

instruments.

M14

A small, bright globular cluster in Ophiuchus. It is a difficult

binocular object, look for a small fuzzy patch of light. Through a

telescope M14 is an even patch of light, the stars not resolvable except

through large scopes.

M22

This is the other great globular in our tour this month. Located

just above the teapot asterism in Sagittarius, M22 can be seen with no

optical aid. M22 is easy to find in binoculars, and easy to resolve in

telescopes, with about the same impressivenessas M13.

M28

Located near M22 in Sagittarius, this is a small bright globular.

A tough binocular object, look for a small fuzzy patch. Easily seen in

a telescope, but requires large aperatures to resolve individual stars.

M69,

M70,

M54

All of these are small bright globular clusters laying

along the bottom of the teapot in Sagittarius. Very similar in

appearance to M28, these are all tough binocular objects requiring dark

skies and possibly averted vision to see. M54 is slightly brighter and

appears more starlike through binoculars than the other globulars.

These are all easily seen in telescopes, though not easily resolvable.
