I got an 8 inch dob about 2 months ago and I have seen most types of objects globs, open clusters, planetary nebulae,and even the c5 reflection nebula what would be some good targets for me in bortle 7 skies? I would like to see an emission nebula because i have not successfully observed one.

Try M57. It's small but has a high surface brightness and is in a comparatively easily navigated location. Planetary nebulae ARE emission nebula.

Get some charts and a subscription to Sky & Telescope and study to become familiar with the sky's observable objects. See this monthly forum string to learn what's well positioned for viewing during a month -  https://www.cloudyni.../#entry11399432

Start with the top ten binocular objects for a month, found toward the bottom of the posts.

Try M17, M20 and M8 for relatively easy nebula observations. But you may have to wait until they are better placed next year. The big sky clock overhead does not bring objects to order but keeps its own schedule. M42 will be around soon and you can see it with your naked eyes.

You could try looking at M31/M32/M101 and M33.

Get up before twilight in the morning and take a look at M42/M43.  M78 is not far away but not as impressive.

Welcome to C/N! welcome.gif You will hear this a lot but darker skies are the key to seeing many of the "faint fuzzies." You will be able to tease out some of the brighter DSO's in Bortle 7 skies but they won't stand out against a black background. That's where the real magic happens IMO. Put your scope in the backseat of your car and the base in the trunk then get to Bortle 3 if at all possible. Best of luck to you! wavey.gif

The c5 reflection nebula?

 

You may still be able to observe M8, M16, and M17 shortly after dark, if you have a good southwestern horizon.

Of course, M42 will be the best possible emission nebula later in the night.

Here's a screen capture from Stellarium showing M8 from my latitude of 40 degrees north at 7:30 p.m. EDT.

By C5 I am assuming Caldwell 5? If so it is not a nebula. It is IC342, a faint face on spiral galaxy in cammel...cammo...cama...the Camel constellation. If you could see this one you should be able to bag a lot of emission nebulae!

Do you have an app like Sky Safari, or the software. (free) called Stellarium? You can select and choose objects for observing. You can see when objects come to meridian at your location.

M8 is an emission nebula, but I guess you missed it for this year as it is in western Sagittarius. The good old Orion Nebula M42 is great fun.

I bet you can find M1, too. Perhaps not an "emission nebula" if you are being overly strict about categories, but, well, it shines by emission so why not. Also M27 which nobody mentioned above, but if you say you've seen planetaries, that had to be one of your first.

 

As for the many popular nebulae that are too dim (or too large) to have Messier numbers, those are very difficult for visual and, I would say, not possible in Bortle 7. They can be very nice photographic targets, though, with an appropriate camera lens (or small telescope) on a tracker. Or EAA. Especially when used with a camera, filters work wonders on emission nebulae, in LP zones.

Try:

That will keep you busy for a while.

All objects can be seen with a 4" scope in dark skies.  Your sky is bright, so even with 8", some of them will be tough.

You'll get better traction here by using the proper DSO designations and not the ones in the Caldwell "catalog".

The Iris nebula is a reflection nebula, but honestly, from a purely observational standpoint, there's no distinction between reflection and emission nebulae. If you can see the Iris from where you are (which I am a little surprised to hear) then most common emission nebulae should not be difficult to see.

Grab a copy of Turn Left at Orion, which arranges targets by season and also ranks them by their impact for both Dob and Refractor users.  Using this I was able to gradually knock off a huge number of the key targets over the past year, of every type, using my 10" dob.

 

I think it's about the best 27 bucks I ever spent.
