| This Celestron universal digital camera adapter allows you to do astrophotography with a digital (point and shoot-type) camera. It turns your 1.25" or 2" eyepiece telescope into a very high power telephoto lens for digiscoping with those cameras that have non-removable lenses, which normally can’t be used for astrophotography. The Celestron adapter allows very high magnification lunar and planetary afocal photography (photography through the telescope eyepiece). The Celestron adapter also works with most straight-through and 45° angled spotting scopes for terrestrial nature photography.
Prefocus your telescope on the Moon or a planet by eye before putting on the Celestron adapter. The adapter has a six-sided jaw that clamps firmly onto your telescope eyepiece. It will fit virtually any 1.25" and 2" eyepiece up to 60mm (2-11/32") in outer diameter. Behind the jaw is a platform to which your camera is bolted using the camera’s standard 1/4"-20 thread tripod mounting hole. The platform has two slots for the camera attachment bolt. Use whichever slot comes closest to putting the camera lens directly behind the eyepiece.
The camera platform has micrometer adjustment knobs to adjust it up or down and right or left. All of these adjustments allow you to center your camera lens precisely on the optical axis (center line) of the telescope eyepiece and lock it in place. This assures that your eyepiece image fully covers the camera’s imaging chip with no vignetting.
The camera’s autofocus mechanism focuses the camera sharply on the high power lunar or planetary image you’ve already composed and prefocused in the telescope by eye. You can also zoom in and out on the eyepiece image using your camera’s zoom controls for a closer or wider angle view. The photographic magnification and field of view will vary, depending on the telescope, eyepiece focal length, the camera used, and the zoom setting of the camera lens. The magnification will be quite high in any case, since you are multiplying the magnification of the spotting scope by the magnification of the camera’s zoom.
Once the adapter is centered on your eyepiece, you won’t have to readjust it if you take the camera and adapter off your telescope for visual use. Simply loosen the knob that tightens the jaw and slip the entire camera/adapter assembly off the eyepiece. When you’re ready to take pictures again, slip the entire assembly back on the eyepiece, tighten the jaw on the eyepiece, and you’re once again aligned and ready to shoot.
The Moon generally will more than fill the field of view of the camera. When the camera is set at the extreme wide angle end of its zoom range, there may be some vignetting of the lunar image (the image will be round and framed in black, rather than rectangular). In such cases, zoom out slightly to eliminate the vignetting.
