The ring nebula in the lyra constallation south of Vega.
Taken with a DSLR Sony A700 with 500mm zoom and x2 teleconverter and cropped quite a bit.
Single shot of 2 seconds with static mount
1000mm 2sec at F6.3 ISO 1600
A bit crap because of the low exposure rate, but all manually guided by a DSLR on a standard tripod. Helps having an easy to find (ish, well not at 1000mm) object
Chuffed because I managed to capture it, which was my only goal tonight. :)
Can wait for my scope and comp driven mount.
In mean time will try stacking piccies of this as have about 20 subs of this.

We all have to start somewhere mate. It looks pretty solid, are you sure it's not a star or planet?
The ring is VERY faint and I am puzzled as to how you could capture it in 2 seconds.
Here's what the Ring Nebula should look like.

Sorry mate but at that scale if that was the ring neb you would have some other stars showing in the frame. As Baz says its pretty faint at Mag 9 so my guess would be that you have Vega a bit out of focus. Do yourself a favour and have a go at some of the brighter targets (Mag 6 or so), M57 is a toughy that is best kept for later.

Been looking and looking at the star charts and the object pictured is definately at the center of the ring nebula to a precise location. I have a shot or two of the larger region clearly showing Lyra layout.
The shot I have posted is a large zoom on an original picture.
Perhaps it is one of the stars in the nebula and I haven't captured the gas clouds of the nebula due to the short exposures and you guys are right, it should be much larger the nebula.
Here is a smaller crop of the picture it came from

Check with another members shoots the other night of the ring nebula and my sky maps with his and it is definately the nebula :)
Here is a link from the other night http://photography-on-the.net/forum/showthread.php?t=700149
I think it looks wierd because of the low 180mm dlsr camera and actually it was comprised of about 10 2 second ISO 1600 shots so was pretty bad data.
edit : Ignore the original picture, you guys are right as ever it is not the nebula. I got it on the wide angle but not on the close up :(
