Sony Cybershot DSC-H20 is not an DSLR or those lens changeable digital camera, so you cannot use prime focus method which use the standard T-ring and T-adapter.

For shooting astrophotography using your camera, you'll be using afocal coupling which mean your camera lens will connect to an eyepiece:
Telescope->eyepiece->camera.

There are two ways to achieve this:
1) I think your Sony DSC-H20 had a 58mm(??) filter thread, but first check with your manual does Sony DSC-H20 had an adapter which provide a thread other than the filter thread, if no, then you had to use the filter thread. Your best bet will be Baader Hyperion 68° Modular Eyepieces with a Hyperion Digital T-Ring, 58mm (check your thread size).

2) Find something which will hold your camera and point towards the eyepiece... something similar to this:

Happy imgaing and good luck.

Have a nice day.

Hi,
No problem.

Anyway, method 1 is the prefer method... it'll be easier to setup and focus.

Have a nice day.

However method 2 can be used with almost any cam if you decide to change your sony cam

You can't take photos at prime focus with a lens on because you'd just end up taking a pic of your secondary and spider. Although that might be fun

Cross hair? If you mean your front spider (the struts holding your secondary)... er..... you need to put an eyepiece between your camera and the telescope first!
