PATH: | The Astronomy Connection Observing Targets November Messier Tour |
---|
This month we will search for seven more objects from the Messier Catalog. These include four globular clusters, the largest and the smallest planetary nebulas in the catalog, and a small oddity. Two of the objects are fairly easy in binoculars, while four others will require dark skies, patience, and keen eyes to find.
m57 -
This smallest planetary nebula in the Messier Catalog is the famous
Ring nebula in the constellation Lyra. Low power telescope views show a
very small blue/green disk, not much bigger than a star. Medium to high
power will magnify the size of the nebula while leaving the surrounding
stars the same size, confirming you have found it. Can be seen in
binoculars as a faint star like point of light.
m56 -
Also in the constellation of Lyra we find our first globular cluster
of the night. In a telescope look for a small round ball of light,
slightly brighter in the center. This is a difficult binocular object
appearing as a small fuzzy patch.
m27 -
Also known as the Dumbbell nebula, the largest planetary nebula in
the Messier Catalog, M27 lies in the constellation Vulpecula. Fairly
easy to see in binoculars as a small hazy patch. In small to medium
scopes it appears as a rectangular patch of light. In large scopes it
may even appear round in shape with a bright rectangular, or dumbbell
shaped core.
m71 -
Lying in Sagitta, this globular cluster appears as a faint oval hazy
patch of light in a telescope. This is a very difficult but possible
binocular object, requiring dark skies and trained eyes.
m30 -
This globular cluster in Capricornus is tough but very possible to
see in binoculars as a faint fuzzy star. Telescopes show a small fuzzy
ball of light, bright in the center fading to the edges.
m72 -
This is a small faint globular cluster in Aquarius. Look for a
faint oval patch of light, gradually brighter towards the middle. A very
difficult binocular object.
m73 -
This asterism is located near M72 in Aquarius. In a low power
telescope view it looks like a very small fuzzy patch of light at first
glance. When stared at it reveals itself as a small collection of stars.
Medium to high power shows the view best described by Messier "cluster of
three or four stars...containing very little nebulosity".
