Default M51, I think...

Took advice from the group and tried for M51...I was looking in the area,
that some star charts said it would be in, and I found a faint fuzzy. In my
excitement I bumped the scope, and lost the image. Never found it again.
*sigh*

Actually it will be two faint fuzzies side by side, M51 and NGC 5195. Dim but
do-able, at least if you can get about 25 miles away from Balto-DC. It's one
that you need to move the scope around to confirm there's something there.

I viewed it a couple nights ago, and what's tantalizing is that it looks like
some structure would be visible it the darn thing was just brighter, or the
skies darker.

Should add that, before it gets too low to the horizon (haven't checked
its position lately) try M104; I saw it from suburban skies in the 60s
through
a 60mm refractor. A 5 inch should star showing some sign of the shape of
the thing, although the dust lane might require an 8-inch or larger, and/or
darker skies.

I saw the dust lane unmistakably in the C5+ from Lockwood. Given good
seeing (it's smaller, and the dust lane thinner, than you might think)
and dark skies, I think it should be visible in a rather smaller scope.
(The dust lane, that is.)

David, 104 is not only is it getting low, but it's not the easiest
galaxy to find for a newbie, unless he already knows about the
'stargate'and 4 star arrow asterisms that points toward the galaxy in
Corvus.
I would suggest and easier "DSO" for a newbie to find...say, globular
cluster M-4 just one degree west of Antares.
OR a brighter one, M-80, about halfway between Antares and Beta Scorpii.
FWIW,
Tom W.

I've always thought that M51 is overrated. There are other galaxies in
Canes Venatici that impress me more..but then I don't have a huge-ass
light bucket telescope either.

M82 kicks m51's ass

.so you search and search...sometimes
you hit it lucky...sometimes you don't....those have to be, by far,
the *toughest* of the Messier objects to locate just by eyeball (telrad)
'sighting'.


I hate them. But love to see them, especially 82
at ultra high powers.


Yeah, M82 is a favorite of mine too.

Plus you probably need 6.5 mag skies to see the stupid triangle. If anyone

has any easy way of sighting in on this duo, I would certainly appreciate any
help in this regard.

For whatever it's worth:

I most often use an 8x50 finder starting from 23 Ursa Major. Traveling about
4.5 degrees past 23 UM on a line from 29 UM there is a 3 star group. When I
find that, I move 4.5 degrees parallel to a line between 23 UM (and towards)
Dubhe and that puts me pretty close. With a Telrad I think one just sort of
points it and knows where it is....

This is what works for me and I can most often find them under the 3.5 skies
that are about the best I have at home. In my experience Telrads work nicely
in dark skies but magnifying finders are a necessity when when light pollution
is a problem. I find having both is the best for me.

Jon,
I have both also....Meade 9 x 60 visual finder...but have a
real hard time seeing 81, 82 at age 61 up thru that finder,
unless in real dark skies.
