Help Lining Up Digital Camera And ETX-105

I have a Meade ETX-105 and a Casio QV3500-EX digital camera with which I want to start taking astrophotos.

I have pre-purchased a supposed method of linking the two together - a set of rings/connectors that allow the camera to physically attach directly to an eyepiece.

My problem is getting any images to appear in the camera's viewfinder at all! If I hold the camera manually and point it into the eyepiece I can get a (giggly) picture no problem. However I notice that to achieve this the camera lens and the end of the eyepiece are not 'square-on' to each other. I don't understand why this is.

Using the attachment rings, I simply don't see anything at all. If I shine a dim light into the scope's main lense I can clearly see this light as a circle in the centre of the camera's viewfinder, but whatever it is that the scope is looking at (the moon, Jupiter etc) is nowhere to be seen.

I can't understand this, but presumably it's something to do with the 'square-on' issue I noticed when hand-holding the camera?

So.. what am I doing wrong? Specifically, how come lining up my camera square-on to the eyepiece (as the attachment system obviously does) doesn't let it 'see' the image in the eyepiece? Is there anything I can do about this?

Any advice will be gratefully accepted!
