The Hunt For the Eagle Nebula new
      #5952501 - 07/03/13 03:52 AM

My Dobsonian Telescopes have been sitting idle in the basement for a few year's tonight I finally took one of them out my trusty old 2002 Orion xt8 first object I looked at was M28 I then proceeded to look for M16
I then saw M17 come into my field of view using that as a guide to M16
from my observation's it looked like a star cluster I do have some moderate light pollution living in the south side of denver colorado so I might have to get a ultra high contrast filter
I then went to Lyra And Viewed M57 then Ended the Night Viewing M13

The Eagle nebula tends to be best seen in a good narrow-band filter like the DGM Optics NPB, although an OIII filter will help it to some degree as well. The nebulosity is somewhat faint, so get to an area of darker skies before you try for it. Clear skies to you.

Yes, the nebulosity in M16 is hard to see without a filter in typical suburban skies. See my discussion here.

I had a nice view (filtered) through a 13.1" Coulter. It wasn't exactly beaming in that aperture and I never made a try with my 8" as a result. However, Jeremy Perez has a very nice sketch with that aperture on his website that's definately worth a visit. Like Dave and Tony suggested however, the sky needs to be quite dark as Im sure Jeremy had.

Hi there Tony. In your article, you posted:

Even under the darkest skies, the nebulosity in M16 is a difficult subject for the visual observer.




I never found the nebulosity in M16 all that difficult under dark sky conditions, although it was never much to write home about unless a filter was used. Even in my old 8 inch f/7 Newtonian, I could see the faint diffuse glow over the cluster and could vaguely make out some of its usual fat "T" shape. However, once a narrow-band nebula filter is added to the mix, the nebula gains quite a bit of contrast, making it appear larger and better defined with notable light and dark detail. Clear skies to you.

Agreed. I built that website years ago, and don't even know how to change it now. But if I were doing it all over again, I wouldn't describe M16's nebulosity as difficult under a dark sky.

Thank you Tony for the filter guide
I was able to observe M16 tonight with a Uhc filter it definitely brought out the faint nebula

I just viewed M16 in a C11 Edge scope at a dark site here in TX. Very disappointing visually! Some 13th mag. planetary nebulae were much more impressive! M16 is a joy to image, though.

Saw a distinct "dented mushroom" shaped nebula in M16 from a dark site in my 4.5" Newt several years ago. Got a beautiful view in my 10" Dob at Cherry Springs a couple of years ago.

Ive probably spent hours on this nebula, with varying ranges of aperture, from 2.75" to 14". I observed it last week with my 70mm refractor with my new 32mm Plossl, yielding 21 power. It's at this very low power that really makes it stand out. Yet, on the same night, I found it invisible even with my UHC filter in the 14 inch. Best was the 70mm with UHC on that particular evening

It actually took me several observations to figure out why it is called the "Eagle" Nebula (not an unusual phenomenon to have to observe something several times to really begin to appreciate it). However, I concur with the idea that it is very difficult without a filter. Several have mentioned a UHC filter, though I've also used an OIII with success.

Doesn't the name come from the eagle-shaped dust cloud embedded in the nebula, and too small to see in an amateur telescope?

That's what I always thought. Its that central cloud obscuring formation later to be called "The Pillars of Creation".

I fully agree.

Even with an Orion Ultrablock filter, all I can see are some stars and some very faint nebulosity in mag 5.2 skies. IMO, it's not the greatest object to see unless you have clearer skies!

I could actually see the general shape of the nebulosity fairly clearly in the 4" Traveler tonight. Rural area and NO porch lights tonight! I was doing Milky Way sweeps first at 20x, then 45x, and then 75x. It showed at all powers, but never bright.

No, the "eagle" is the overall shape of the outline of the nebula. The central dust lane in the nebula is quite small and narrow, but is visible in moderate to large amateur telescopes (10 inches and larger) equipped with filters. That lane contains the famous "pillars of creation" that the HST imaged in high detail. You can't see the fine detail of the Hubble image, but you can see the finger-like dust lane. Clear skies to you.

Observing M16 a few nights ago with my 9 inch scope, I tried both an OIII and an H-beta filter. Both filters helped greatly with observing the nebulosity. I didn't manage to detect the dust lane, though.

I have had the chance to put this to paper from a high moutain top (6500 ft)with my 15" scope.The nebulosity is very apparent with these conditions as is the fingers of creation.The eagle shape is seen if you flip the sketch over, but from the newtonian the image is upside down giving it more of a mushroom look at the eyepices.

John, Awesome sketch. I had a very similar view of the Eagle Nebula, a few years ago now, while attending the Mid Atlantic Star Party. I was using my C11 with a 13mm Nagler and a new UHC filter. Although the field-of-view was much smaller, the pillars of creation were very clear and easily seen, even though most people look at me kind of funny when I say thay. So your observation looks a lot like my view of this object, Good job.
