I was wondering how good my stargazing will be as I don't have much open sky-----I live in a cove in the mountains.
If a full open sky would be 180º-----I think I have about 80º open east to west & bout 65º north to south ( mostly open to the south). Also There is no cell phone service/signal here at my cabin. All my veggie plants grow tall as not much sun gets in here. Hope the video link works---if not I will fix it.
I have made a video to try & show that-------

The south is the single most important direction, since celestial objects culminate (reach their highest point, i.e. upper culmination) there.

Even so many southern declination DSOs will probably be below your tree line.
What's your latitude?
Sic itur ad astra!
Chance favors the prepared mind.
A man is a small thing, and the night is very large and full of wonders.
The video works fine for me ... wow, that is a restricted view.
If that is where most of your observing will be done, then you're going to want to chart your clear horizons well so you'll know from start charts or software when your targets will be in their best positions for observing.
As Dave points out, that is normally in the South -- which is where they'll culminate (be as high above the horizon as possible) nightly. But since you are surrounded by trees, your treetops become your new horizon and you'll have to take that into account.
Also, be aware that the respiration of broadleaf trees can be a problem for astronomical seeing. You can determine the extent of the problem by observing a Quarter Moon ... it will be bright enough to allow you to see the respiration plumes of the trees but not so bright as to overpower them. The patterns will look like "heat waves" over a warm highway and will make the bright highlights of lunar crater rims and mountains appear to waver or even twinkle at high magnification.
You have several different varieties of trees, so determine in this manner which are a problem and avoid observing directly above those trees if you can.
In any case, you must make the best of what you have and go from there. I don't know anything about your location other than what you've written or shown in the video ... is there a clearing nearby to which you have access?

Come visit me at Comanche Springs Astronomy Campus (we're on Google Maps) in Texas.
Dave--- My Latitude is 22.214.171.124----------I'm at 3150' elev.------There is mountains of 4300' that block a a low view of the south.
Now off I go to watch your link
Thanks Jeff----No clearings near by that would offer much more sky view----looks like I will have to make the best of wat I have.
Guess I will just have to buy a telescope & find out
Yep, I figured!
Well, the good news is that as the Earth turns daily the stars wheel overhead at night. You probably have about the same observing window (except at a different lat/long and elevation) as the big dish at Arecibo, and it lets the Earth do the aiming, for the most part ... you're in good company!
I'm bak again----
Cause of my limited open sky I'm now not sure if the computerized one is what I need---
http://www.telescope.com/Orion-IntelliScope-to-PC-RS-232-Connector-Cable/p/5222.uts (or the one on sale)
Maybe this one would be OK for me--$349.99
Maybee I just need to flip a coin
Is there anything else I need to get-----A moon filter---A red flah light---Star Charts
Will this gizzmo put what I see in the telesope on my computer------If so I can capture the image. I understand it needs a USB adapter connector.
If you are willing to learn the sky and enjoy doing a little hunting, the classic version of the Orion 8" is a very nice scope.
All three of the accessories you mentioned are musts for enjoyable viewing. When asked about charts for beginners I always recommend the Pocket Sky Atlas;
I still use my copy extensively even with my 18" scope.
Another accessory you will probably find useful is a Telrad finder. The Telrad makes getting close to your target very simple.
The cable you linked to only allows you to use your laptop to download targets from sky simulation programs like Starry Nights to the controller on an Intelliscope. It will not transfer images from the scope. To do that you would need a camera (DSLR, CCD, Webcam, etc) attached to the scope. Astrophotography can be a complex undertaking. Here's a thread dealing with the basics;

18" Obsession Classic dob #1665
10" Orion Skyquest Classic dob
120mm Orion ST achromat
15 X 70 celestron Skymaster binoculars
You may want to purchase an introductory observing guide such as Nightwatch and a planisphere, as discussed in my post at cs.astronomy.com/.../49111.aspx
A binocular appropriate for astronomy, say a 10x50, is also worth considering.
I've never found a moon filter to be necessary but a narrowband nebula filter may come in handy.
Hey Guys----Ready to place my order--either today or Monday.
I have allready ordered the Sky Atlas listed above.
I have decided on the ---Orion SkyQuest XT8 Classic Dobsonian Telescope
Also on the same order With ---
Orion Safety Film Solar Filter for 8" Reflector Telescopes
Orion SteadyPix Deluxe Camera Mount
The Telrad Finder will have to be orderd from--www.optcorp.com/product.aspx ----Orion does not carry one. But I want one & will order one soon as I get off here.
I'm at bout $500 rite now.
Now then ---------is there anything else I need---eye pieces etc.. ( I have a red flash light some one gave me)
Ya All have been a great help----I have much to learn---But once ya stop learnin THE FUN STOPS
You're definitely going to need more than the one eyepiece supplied with the XT8. You may want to considering picking up something like a 9mm 60 degree AFOV Celestron X-Cel LX, a very fine performer, and a 2x Barlow lens, which will give you focal lengths of 4.5mm (266x), 9mm (133x), 12.5mm (96x), and 25mm (48x).
The Baader Planetarium Hyperions are a bit more expensive but have wider apparent fields of view (68 degrees) and are also very good bangs for the buck.
A 2" wide-field ocular with a focal length of 32 to 40mm will greatly maximize the true field of view of your telescope.
I have put the---http://www.telescope.com/Accessories/Barlow-Lenses/Orion-Shorty-125-2x-Barlow-Lens/pc/-1/c/3/sc/ Into my order.
HOWEVER---after that I watched the video about eye pieces-----They talked about Eye Relief lens---So I'm wondering cause I am farsighted ( need glasses for reading )-----Do all my eye pieces need to be this type----even the one that comes with the scope?
Farsighted and nearsighted people need no special eyepieces at all. They simply adjust the scope's focuser to their need. This is a common worry among newcomers but it's quickly dispelled.

THANKS for that info Antitax----
I checked the other link by Dave---bout the Baader-Planaterium 5mm-125 eye piece-----It says ---Backordered from the manufacturer. ( bit high $ too). So I gotta get this order in .
Need to get started-----I'm sure I will have more questions.
Soon after I posted I was thinkin that I don't wear my glasses when using my 7X50 binoculars.
I didn't mean to suggest buying the 5mm Hyperion. A 10mm, in place of the 9mm X-Cel XL, would be a far better choice.
Actually, the Hyperions are at the very low end of the premium eyepiece cost scale. The no-longer-made 30mm Leitz Planokular ran about $1500 at one time in the United States.
