M102 new
      #2519686 - 07/15/08 03:51 AM

hello people.....

atlast I have found M102!!!!!!!!!with my 6"refractor achro F/5......well all I can make is a dim star in the middle between two stars and I can't see no cloud around it like the M94 I observed as a star in the middle and hazy cloud around it.now this adds to my 35th messier object atlast!!65 messiers to go!
Say how do you see the eagle nebula? everytime I go there and I can't see it I know im right on the target.but seriously I see no nebulosity

Make sure you've got darker skies - That one really seems to get killed with light pollution! You can also try a filter (UHC or OIII), as I've had good luck with a UHC.

Darker skies are the name of the game, though. As a buddy of mine says, "The Best observing accessory is a full tank of gas and a few hours' drive to a dark sky site!"

Cheers!

hehe Iam already there and can't believe I have escaped light pollution for 3 month at a cost though humidity! I see the ring nebula ,dumbbell nebula and the omega nebula which I happen to bump in and think its the eagle nebula. here is the eagle nebula link http://www.maa.clell.de/Messier/E/m016.html
if you take a look to the bottom right there is cluster of stars. Thats what I see only and I keep searching the area until I meet omega nebula everytime lol!
I guess im going to leave this nebula alone until our Moon goes away and try to get it again!.

Do you know any site that I can make a dew control system so my telescope Objective won't be foggy:((

On M16, I have a 10" dob and still can't see anything. Even after I put in the Ultrablock, there's VERY little nebula to pick out. The cluster is pretty, so enjoy that as well. There are plenty more fine nebulae around. The Blue Snowball and the Blinking Nebula ( Blinker ) are 2 great clouds, and are pretty easy to find by starhopping, but go slow, they're small and look like stars if you go too fast. If you move slow, the little dot doesn't look the same as a star. The Omega is pretty to, and it's big and bright in the filter. So, the cluster is all you'll see, no nebula, unless you take pictures of it. Keep enjoying those other Nebula's!

At low power with a narrowband filter (Lumicon UHC, DGM NPB, Orion Ultrablock), you should see M16's cluster plus a sort of fat "T"-shaped dim hazy area on top of the cluster. That is the nebula. At a dark sky site, the nebula is easier to see, but it doesn't show a lot of detail unless you study it for a while. Clear skies to you.

I do see nebulocity, but it's not much, just a little patc near the cluster. Clear Skies.

I need to use my OIII filter to see any nebulosity in the Eagle and even then it isn't much. Without the filter, I get nothing but the cluster.

yep... very little grey matter is seen (in both M16 and the observer sometimes ). My UHC or O-III helps, but only a little.

But within a bump of the scope is M8, M17, and M20... which are all very nice, especially with a NB filter. I usually just get lost in M8 until the boss comes up and "coaxes" me in.

M-16 requires very dark skies and or a nebula filter. Narrowband and O-III's are the one to use on this large and faint nebula that surrounds a star cluster. Chances are you did see the star cluster but missed the nebula due to interference from moonlight, haze or ever worsening light pollution. Wait until the next weekend after this one, go to a dark site where you won't have to contend with lights, and take a low power wide angle eyepiece and a narrow band nebula filter if you have them. Your 6-inch should at least show a large, patchy glow around the open cluster forming right now within the Eagle Nebula.

Just to put this all in context ...

The nebulosity in M16 is obviously a lot fainter than in M17 or M42, but that's not saying much. If you plotted a bell-shaped curve of all emission nebulae, M17 and M42 would be off the chart. The Eagle remains one of the brightest and easiest-to-see emission nebulae in the sky. Much more prominent, for instance, than the North America -- which isn't exactly a shrinking violet.

Yes, a nebula filter helps a lot. Using a UHC filter, I've even seen the nebulosity through my 70-mm scope from my local urban park, deep inside the white zone on the Light Pollution Atlas. That would be unthinkable with the North America.

Obviously, dark skies help a lot with this or any other nebulosity, and the darker the better. However, the nebulosity is plenty easy to see, even without a filter, in skies that are very far from pristine. It should be possible at least to glimpse it from any reasonably dark suburb.

Also with M102, did you see M102 ( M101 ) in Ursa Major, or the one in Draco? Somehow, Messier confused it with M101 in U Major. The M102 in Draco is actually NGC 5907. I saw it to, it was oval-shaped.

Well, not quite. From the historical reference (including Messier's and Mechain's notes), there is some evidence that the entry for M102 may have been a duplicate observation of the spiral galaxy M101. The issue is a bit confused, as there were some problems with the position given by Messier. However, around 1917, the suggestion was made by the astronomer Camille Flammarion that Messier may have actually seen the lenticular galaxy NGC 5866 in Draco. Later on, this suggestion was adopted (even in most professional circles), so now, NGC 5866 is usually designated as M102. NGC 5907 is a nice needle-like edge-on spiral about 1.4 degrees east-northeast of M102, but it is not the one currently designated as M102.

Clear skies to you.

I used stellarium to find M102(draco) even though I was off by half a degree or less(goto).However, I only see the central star which is really dim a triangle shape.M101 pinwheel galaxy(ursa major)continues to elude me and I know why...due to the white mist thats making the galaxy impossible to observe.

I think I made a mistake finding M102 Im going to observe it again. It should appear as a hazey white cloud in a 6"refractor right?

It should be a small dim spindle or lens-shaped fuzzy patch with a slightly brighter middle (no central star). There is an 11th magnitude star off the north-western end and another slightly fainter star just south-west of the galaxy, so the two faint stars kind of bracket the galaxy. Here is a modified Digital Sky Survey image to try and show roughly what it might look like in relation to the stars around it (north is at the top and west is to the right):

luckily just now I aligned with deneb and vega and landed at M102 at the bottom of the eyepiece. So , I centered it and as you shown here in your image. you see the two stars between the galaxy?thats what im seeing right now and I can't see no cloud.The Moon +the white mist is killing me:((

You can't view very many galaxies with the moon in the sky, especially in only a six inch. Wait a week or so and try again when M102 is high and you have access to a dark sky. I tried tonight with my little 4 inch refractor and did see the wide triangle of 8th and 9th magnitude stars whose hypotenuse has M102 sitting in right on the line, but the galaxy itself was not seen. Even the two 11th magnitude stars which bracket the galaxy itself were hard to see. Once the moon is out of the way, the galaxy should be considerably easier to see. Clear skies to you.

Yep, David's right - The moon and any haze kills the faint fuzzies FAST. It's amazing how dark skies make everything easy to see and find. Plus, a dark site can't be beat. A buddy of mine puts it well - "The best observing accessory is a full tank of gas!"
