Attaching a video camera to a telescope

Sorry everyone, but here is another topic on connecting cameras to telescopes

Well, the time has come. I want to update how I attach my video camera to my telescope. If you see the image I attached to this post, I think you would agree its time for an upgrade! I have attached 2 images of the front of the video camera onto this post so you can see where the thread is and how it works.

So I have been reading some of the older posts and looking around the websites of some Australian vendors. It seems I have two options: the Prime Focus method or the Eyepiece Projection method. I have been using 2" eyepieces in the past and I wish to continue using them.

What sort of adapters would I need for either method? I have been looking at some images in other threads posted by other members laying out the required equipment (such as these images by Dennis: http://www.iceinspace.com.au/forum/a...0&d=1170894740 and http://www.iceinspace.com.au/forum/a...&d=1170894740). However, SRL cameras appear to be a bit different to my video camera.

Prime Focus:

From the looks of it I would need something like this...

Would I need a T-thread with this to fit my camera, or is it supposed to be a fairly generic thread. Too add to this, I'm not really sure what the thread size of my camera lens is. However, it has 43mm diameter written on the inside of the thread.

Eyepiece Projection:

I think this is the method I would prefer to use as it would give me a greater variety of magnifications to work with. But I have little idea at all what kind of equipment I would require. I am thinking something along the lines of a tube that connects to the outside of the 2" eyepieces that has a thread on the other end that I can screw onto the camera lens. Is this the kind of thing I should be after?

Furthermore, I have seen some products like this (http://www.myastroshop.com.au/produc...asp?id=MAS-238) that would be good as they would simply be better built versions of what I am currently using. However, I haven't yet found one that will fit my 2" eyepieces (the one I just linked too only takes an eyepiece with an outside diameter of 45mm where as a standard GSO 2"er is at least 50mm.)

Sorry for my complete newb-iness at this! There just seems to be so much variety and I have gotten myself into a muddle with all the different threads and adapters.
