Telescope/digicam adapter?
Is there a Camera Adapter that:
1- Will slide into a Telescope Focuser (either 1.25" or 2") on one end.
2- On the other end will be screwed to a digicam (the same way a 52mm filter would).
The objective is to connect to a telescope a digital camera that has the threads for filters but does not have a removable lens.
Thanks for any advise!
Since you can't remove the lens on your camera, you will need to include an eyepiece, and the afocal adapter you need will undoubtedly be designed to hold one.
Here's a web site with various options - though the 52mm one isn't in stock. On the other hand, if you can get one that's close to 52mm, you can probably get a camera step up/down ring to get to the size you need.

A lower cost way to do this is with one of these:

The drawbacks to the lower cost system are it's apt to be a less sturdy coupling, and stray light could get between the eyepiece and the Camera Lens. (though you might make a light shield out of black construction paper)
Low power eyepieces (for example a 40mm one) will give you a lower power/wider field of view, and higher power eyepieces (8mm) will give you more magnification and a reduction in the field of view.
If your camera has a zoom, you'll be able to use it to adjust the image size too - though sometimes only a portion of the zoom range will be useful.
A limiting factor will probably be the length of exposure your camera can take. For Deep Sky objects, you'll get better results if you can take exposures that are measured in minutes instead of seconds.
Good luck!
