April Messier Objects

Spring time is galaxy time. As the winter milky way sets into the west

we begin to get overhead, clear views outside of our own galaxy. During

April we will begin in earnest our search for elusive galaxies. We will

be searching for very distant objects, thus in general they will be small

and faint.

There are several things to keep in mind to be successful at hunting

distant galaxies. The darker the sky the better. Search out dark sky

sites, or wait until the desired target is at maximum altitude or passes

through relatively darker portions of moderately light polluted skies.

Search with low power, once a possible fuzzy is found switch to higher

powers for confirmation and to look for more detail.

Nearly all of the objects this month are possible in binoculars, though

most need dark skies, averted vision, and a trained eye to see. We will

be hunting eight galaxies and two objects from our galaxy, a double star

and a planetary nebula.

M40

This is a pair of faint stars located in Ursa Major. They are a

tough find in binoculars, and you will be challenged to split them

with binoculars. In telescopes, they appear to be an identical pair of

stars and easy to split even at low power.

M108

This galaxy will appear as a thin streak of light in telescopes,

there is a definate brightening towards the middle. M108 is a very

tough object for the largest binoculars.

M97

This planetary nebula in Ursa Major, also called the Owl nebula,

appears as a fairly large, round, hazy patch of light in a telescope.

It is in the same field of view as M108 at low to medium powers. Use

averted vision to see the faint glow of the Owl nebula through binoculars.

M109

This spiral galaxy in Ursa major appears as a small, oval patch

of light. It can be found in the same field of view as Gamma UMa at

low to medium power in a telescope. Use large binoculars under good

conditions for a chance of seeing this one.

M106

This galaxy in Canes Venatici appears as an oval patch of light,

larger than M109, with a fairly bright core. A tough, but possible

binocular target.

M95

This galaxy in Leo appears as a faint round patch of light with

a bright nucleus. Large binoculars and good conditions a must.

M96

Look for M96 in the same low power telescope field as M95.

Another round patch of light, slightly larger and brighter than M95,

it too has a stellar core. Binocular advice for M96 is the same as M95.

M105

This is a small elliptical galaxy in Leo, and can be found in the

same low power field as M96. It look like a small fuzzy star. M105 has

a close companion galaxy, NGC 3384, which is only slightly smaller and

fainter than M105. To prevent consion, M105 is the closer of the pair to

M96. Not possible in binoculars, except maybe with averted “imagination”.

M65

A small, but relatively bright galaxy in Leo. It is an elongated

oval patch of light with a bright stellar core. A tough, but possible

binocular target.

M66

A close companion galaxy to M65, it can be seen in the same low

to medium power field as M65. M66 is another oval patch of light,

brighter and slightly wider than M65. Another possible binocular target.

While you are here be sure to look for the a thin streak of light

which is the galaxy NGC 3628. It can be found north of M66 in the same

low power telescope field as both M65 and M66.
