These were taken with my camera coupled to the eyepiece on my telescope. Focusing is tough and a remote release helps. The Nikon 4300 also has a video out port which I connect to a b&w monitor for focusing. I find these challenging.

Eric, could you elaborate on the method? Do you use a thread-on eyepiece
(like a scopetronix) for the magnification? I have experimented with the camera
holder, eyepiece mount and most recently with a T-ring.
Thanks!

Ian, I use ScopeTronix digi-T system of eyepiece projection. It mounts the camera directly to the eyepiece of choice. My Nikon 4300 is fairly light, so the weight on the eyepiece is no problem. My scope uses 1.25" lenses. The procedure is as follows: I orient the scope and get the tracking system going. I mount the adapter ring to the camera, which is really a tube since the 4300's lens extends out from the camera a bit. In eyepiece projection, your camera is actually taking a picture of the image as in passes through the eyepiece, where it is focused. The adapters are set for the closest possible focus of whichever camera you have. Mine ends up about 1 1/2" from the eyepiece. The rubber is removed from the eyepiece and the mounting ring is clamped on the eyepiece. It's threaded on the outside to recieve the camera. Without the camera, I take great care in focusing with just the eyepiece, when that's set, I remove the eyepiece and thread it on to the camera. The the whole set up goes onto the scope. I have a remote release cable for the 4300 which will do everything I need so you don't have to bother the scope. I shoot in manual mode, MACRO. Macro because you are taking a picture of the eyepiece image. I manually focus either using a large magnifying glass on the cams view screen, or I hook up the camera to a 9" black and white security monitor. I bracket the exposures usually starting at 1/60th at f/4, ISO 100. I sometimes will bracket the focus on the scope, making minor adjustments as I go.
I also have some pictures of a forrest fire I shot at night through my scope. This yielded some interesting pictures which I'll post in another thread. Thanks for your interest.

I'm north of the equator, so I look at the side facing me.:D Actually Sea, I don't know...I think the whole world looks at the same side. Hmm.

That's a nice picture.
Have you tried using Astrostack (http://www.astrostack.com/)?
Allows you to mung several images to make one. Most useful if you shoot
video or make a number of images.

I've tried using Astrostack, and had some problems trying to figure it out. I need to spend some more time with the program.
