Subject: what galaxy


For someone in the US Pacific NW, around Olympia WA what is a good candidate
for an easily viewed galaxy? I only have a 4" reflector. I'd like to see
something that i can easily make out the shape of.
Any pointers ? :-) (pun intended)
My sky conditions are typically this: By naked eye I can sometimes see the
star at the point where the handle of the big dipper meets the dipper
itself, and sometimes not. When i can see it, its faint. I've got good
enough conditions so with my 4" telescope I've seen 5 of Jupiters moons,
and then all at once, very impressive sight! I can see Saturn and its rings
but its tiny. People have referred me to the Andromeda galaxy but I'll be
damned if i can find it. I've tried 10x50 binoculars also, and I just cant
spot it.
Thanks
Eric

M31 is still your best bet. I always sight from the "sharp"
point of Cassiopeia (Schedar, Alpha Cassiopeiae) to
Beta Andromedae. It's not that difficult to find, but it's
not going to be much more than a vaguely elliptical
smudge.

Dark skies make an enormous difference: the last new
moon I was at a place that was dark enough that M31 was
obvious to the naked eye, and I could see M33 as well.
The view through a telescope was a revelation, with
the main dust lane in M31, and spiral structure and
NGC604 in M33.

There are other galaxies in range of your scope (e.g. M81),
but it's the wrong time of year for them, and they too will
never be more than a faint grey smudge on the sky.

5 moons of Jupiter? In a 4 inch? I think not...

It was quite obvious, perhaps they were stars close to it but they were very
tiny but bright points and made a straight line slightly diagonal across
Jupiter, ie draw a line from outmost left to outermost right and they all
would be very close to being on the line

I saw what you did a few months ago. The fifth 'moon' was a background
star. It was just a coincidence that it lined up with the others.

M31 would be a simple target even in polluted skies, though you don't
appreciate much more than a blurred smudge. Easy to find. You just have to
imagine how big it is, as you are only really seeing the inner, brightest
part. Once you see it in a truly dark sky it will bring back memories when
you see it again. Seen without that memory it is mildly disappointing.

M31 is by far the brightest galaxy visible in the northern hemisphere,
but in a place with mag 4.5 skies (like yours), it's still not a slam
dunk. 10x50 binoculars should be enough, but only to show a faint
smudge. 15x70 binoculars would make it easier. But you still need to
know where to look.

The easiest solution is, of course, to drive off someplace where it's
darker!

M31 is the easiest galaxy to find and see from your location under
your sky conditions; but you'll only be seeing the inner portion of
this galaxy.

The shape (an oval with indistinct edge and brighter center) will be
that of the galaxy's inner region. To see more you'll need darker
skies and/or greater aperture. Experience is another factor in how
much you'll see.

Your 10x50 binoculars *might* be better than your 4" telescope for
finding and viewing M31.

Besides M31, M81 is probably the easiest galaxy to see with your
telescope from your location. Unfortunately, under your sky
conditions it will be difficult to locate this galaxy (no stars
visible to the unaided eye nearby to help you point your telescope to
the right spot in the sky).

Once you find M81, chances are good that you'll also see M82, a fairly
bright, nearby galaxy. These two galaxies will be better seen with
your telescope than with your binoculars.

M81and M82 will be higher in the morning sky at this time of year than
they are in the evening sky. Look for them in the morning after the
moon's gone, but before the first hint of morning twilight.

Taken into account.

Under your conditions you should be able to see M31 with your 10x50
binoculars. Don't give up too quickly. Point your binoculars at Beta
Andromedae, then scan past Mu and Nu to find M31.

It helps to do the best you can (difficult in the presence of lights)
in allowing your eyes to dark adapt prior to looking for these
objects. Also, galaxies will sometimes disappear when you look
directly at them. Use 'averted vision' -- the art of seeing without
looking ;-)

When looking for these galaxies use your telescope's lowest
magnification. M81 and M82 are small compared to M31; but they're
still plenty large enough to see and recognize using your telescope's
lowest magnification (They're both visible in 7x binoculars from a
dark-sky location). Expect to see nothing more than faint, nebulous
blobs of light -- stains against the background sky. You *might* see
more; but it's best to expect no more.

Yes. Even the core visible to the naked eye under dark skies is quite a
bit larger than the Moon. So are other well known objects like the Orion
Nebula and the Pleiades. But don't expect any of these to be perceived
as larger than the Moon unless you are very discerning; the Moon appears
much larger than its actual size, due to one or more optical illusions.

Yes, from a -very-dark-site. In light polluted skies the less dense outer
part of the galaxy will blend into the background sky, and you will only see
the smaller, brighter core. You should see an elongated gray blob that fits
neatly in your lowest power field of view. If you do go to a very dark
site, you should see enough of the galaxy to more than fill the field of
view.

True, but from the OP's location I think this is the only one he'll be

I live in Santa Monica, a suburb of Los Angeles. I commonly observe
with the 5-inch SCT referred to in my .sig, a scope which is quite
similar in terms of grasp to a 4-inch refractor. In my experience,
M81/M82 are easier than M31, which in turn is easier than M51. None of
them is very hard, though. M82 shows quite a bit of detail if you are
willing to be patient and use high magnification. This results in a
view which may not be as aesthetically pleasing, but makes what texture
there is in M82 (and there's quite a bit) easier to see.

Incidentally, the original poster quite obviously did not see five
satellites of Jupiter, since the fifth one is far, far dimmer than the
Big Four. It must have been a star that happened to be in line with
the satellites, an alignment that happens quite frequently.

I disagree. M31 is not an easy object unless your skies are pretty dark.
It's just too diffuse, and is lost in any skyglow.

This isn't my experience. Back when I lived in Southern California (much
worse skies than the OP has) these three objects were always good
choices. M51 is easy as a smudge, although you need darker skies to see
much structure. M81/M82, on the other hand, clearly show their shapes
even under bright skies. These are a couple of the brightest object up
there- much brighter then M31. All should be visible as smudges in
binoculars, and all should be very obvious in an 80mm or larger scope.

M31 is easy, so you're probably just looking in the wrong place. But
that said, forget M31. It's not a nice galaxy visually. It's too big,
and too low contrast. Basically, it's just uninteresting visually.
Expert observers learn to see detail, but it's hard. You might as well
watch a cloud, IMO.

You want smaller, brighter objects. My favorite is M51, which shows
structure even under moderately light skies. Also very good are M81 and
M82. All of these can be found with binoculars, and will show well in a
4" instrument.

You need to get a handle on your light-pollution problem. I suggest you go
to:

http://cleardarksky.com/lp/OlympiaWAlp.html?Mn=astronomy

Also, you should join your local astro club, where you will meet folks who
can help you to get the most out of your observing and equipment.
Hopefully, they are a lot of fun to hang out with as well.

They were stars. Jupiters's 4 large moons are visible in binoculars.
The smaller ones are out of reach of all but the largest amateur
telescopes. There was a similar issue last year when Saturn passed
close to M44 and there were numerous field stars that looked
like moons.

A lot of this thread comes down to two questions, that come up a
lot in this newsgroup. They are:

1. What can I see in my telescope?

2. What will it look like?

My answers, FWIW:

You can see quite a bit in your telescope, even under
your skies.

Many objects will look interesting, but galaxies (even M31)
aren't going to be much more than an elongated silvery-grey
blur. I'd concentrate on the moon, the planets, double stars,
star clusters, and so on.

There was an article in Sky & Telescope a couple of years
ago about how various Messier objects fared under urban
skies. You might want to dig it out of the archive.

M81/M82 are good in the pre-dawn hours, if Eric can observe at that
time. The light pollution is better then, too.

No question about M31 being easier to find, though.

Lots of good info from the gang.

In my opinion you should start out by locating the brighter galaxies
mentioned here, not for detail, but simply to become familiar with where
they are. Visit them often. Don't give up on looking for them if you
can't find them at first. It is possible that you are in the right
place, but your eye isn't yet trained to pick them out.

The M81/M82 pair were the first galaxies I ever detected, using my very
first scope, a 4" Mak. Years later they are now super easy to see, and
detail is not out of the question for M82 even in a small scope.

M51 is my favorite galaxy to observe in any scope, as it is likely to
reveal its spiral arms with relative ease, given darkness, experience,
and 6" or so of aperture.

Galaxies are one of, if not the most difficult objects to observe for
detail. The more times you go back to them, the more you will see, until
your sky or your scope become the limiting factor. They are also very
different in appearance one from the other. Some are an oval haze, some
a round haze, some have bright cores, others dim, some extend brightly
beyond their core, others not. There is a huge gamut, but mostly they do
appear as non-stellar objects. Another good group to look for is the
M65/M66 pair in Leo.

A dark sky provides more gain than a larger scope, so before you go off
and buy a 12" Dob to observe from your backyard, consider the
possibility of traveling to your nearest dark site with something more
portable (6" to 8" is reasonable).

At this point in my observing career, I can now find and see the dual
cores of M51 and companion (which are just off the handle of the Big
Dipper) using an 80mm refractor. On a good night, when it is high
overhead, it is possible to see the glow of the spiral arms using
averted vision, although detecting the arms themselves is not likely
with less than a 6" scope under my skies (mag 5+ overhead).

Try observing galaxies when they are high overhead, as you will be
looking through less atmosphere.

Another interesting object that appears like a galaxy, is the super nova
remnant M1 in Taurus. It is located north from the head, out toward the
end of the eastern horn, in the direction of the Gemini twins.

Happy observing!
