I use a Meade ETX-90 both with my CP950, CP990 and Canon D30 this way. Many of the astro-telescopes also have fixed focal length ports where you can use a standard "T" mount coupled with a "T" adapter tube to connect any film or digital removable lens SLR camera to them.

This eyepiece limits you to the Nikon CP series cameras, but the CP995 has 4x native optical zoom which really gives one a broad range of power and framing choice with the William Optics eyepiece. You can use it directly with any telescope which takes the 1.25" (many astro-telescopes) eyepiece, or directly with the Pentax PF80-ED spotting scope, or with the Swarovski spotting scopes with the 1.25 Astronomic Eyepiece Adapter (Part # 629-0307A) which is about $65 U.S. The other end of the William Optics eyepiece is a standard 1.25" astro-telescope standard.

This serves to allow a much greater than normal "zoom" range so that framing is much easier and rather than being stuck with full zoom in, you can vary the "power" by using the cameras zoom.
There is a new solution: William Optics (Taiwan $99 U.S.) has an eyepiece which directly attaches via 28mm threads to the Nikon CPxxx (CP950, CP990, CP995, CP500, etc.) cameras and has a much larger than normal lens on the camera side. To change the framing any great deal would require changing eyepieces - not easy when the target is live and likely to loose patience with the photographer and leave the area When you do this, there is a fairly stringent limitation in the degree of "zoom" available to you without extreme vignetting. You then must use either the "finder" scope (in the case of an astro-telescope) to find the target, then focus the main scope and camera by looking through the LCD with something like the Xtend-a-View 2x loupe/sunshade - or, in the case of a terrestrial telescope, just find AND focus both the telescope and the camera by using the LCD. The reason this is important is that the most common way to attach a telescope and camera together is with a coupling device which mechanically puts the camera lens in proximity with the telescope's eyepiece. At what range will your target be, and what size (birds, deer, etc.). Several other factors come immediately to mind. Many of us are using both terrestrial telescopes and/or astro-telescopes to shoot long range telephoto shots. There is LOTS of information on this site and others under the heading "digiscope".
Since you mentioned a 1.25" eyepiece, I assume you either refer to an astro-telescope, a astro-type spotting scope, or a Pentax PF80 ED spotting scope (which use the 1.25" astro-eyepieces). Second, do you already have the telescope, or do you plan to buy that also. First, what are you going to do with the captured image? Just for screen viewing, or for printing, etc.? This will determine the resolution you need to shoot for in your digicam.
Several things enter into this scenario which you should consider. I am willing to buy a newĭigicam for this purpose. Would like to haveĪutofocus and at least 2 megapixels. To attach a digicam to a to a standard telescope with 1.25"Įyepiece via the camera's lense thread. I am interested in long range terrestrial photography.
