Celestron 2" to 1.25" Adapter with Twist-Lock
Celestron SKU:93668 | Helix SKU: CT93668
Overview
The Celestron 2” to 1.25” Adapter with Twist-Lock was designed for visual observers who use both 2” and 1.25” eyepieces regularly and need a quick adapter to use with the 2” barrel.
The twist-lock eyepiece holder secures eyepieces while keeping them centered in the adapter, providing best opto-mechanical alignment between the telescope and eyepiece. Unlike traditional thumb screws, the twist-lock cannot scratch or engrave the barrel of your eyepieces. The adapter has an integrated 1.25” barrel stop that prevents 1.25” accessories with long barrels from damaging the mirror.
All the adapter’s mechanical parts are made of machined black anodized aluminum, except the twist-lock rings, which are orange anodized for visibility.
Save Time and Money when using Eyepiece Filters
If you want to look at an object under different eyepiece magnification but keep the same eyepiece filter, thread your 2” eyepiece filters to the barrel of the adapter. Since this adapter accepts 2” filters, you can also save money by buying fewer 1.25” eyepiece filters.

Overview
The amazingly versatile Celestron 8mm - 24mm Zoom Eyepiece allows you to choose from a variety of magnifications in a flash! Simply grip the rubberized barrel and turn it slowly while looking through the eyepiece, and then pick the best power for the object you are observing. Alternatively, you can use the lowest magnification (24mm) to find an object and center it in your field of view, and then increase the power until the desired view is achieved. It is fast and easy, and lets you examine any object at various magnifications without requiring you to physically change eyepieces.
The Celestron 8 - 24mm Zoom Eyepiece uses premium optics that are fully multi-coated for crisp, clear images. The folding eyecup lets you view with or without glasses, and the field of view (40 - 60°) works well for terrestrial observations as well as for views of the Moon, planets, and deep-sky objects.

Nikon DK-17C 0.0 Correction Eyepiece
Nikon SKU: 4758 | Helix SKU: NK4758
Overview
Five correction lenses from –3 to +2 m-1 for circular-eyepiece cameras.
Correction lens, 0.0 strength, for Nikon D-SLRs that feature a circular-eyepiece.
Optional Nikon eyepiece diopters allow you to optimize your SLR viewfinder’s sharpness in conjunction with your individual eyesight. Eyepiece diopters are designed for specific camera models and are identified by a plus, a minus or a neutral numeric diopter value.
Standard eyepieces supplied with Nikon SLR cameras have no corrective value and are for dust protection only. Select eyepieces are supplied with a rubber coating designed to lessen scratching of a photographer’s eyeglasses.
Nikon SLR cameras (without built-in adjustable eyepiece correction) have a base diopter value of minus one. This is why you won’t find an accessory Nikon eyepiece diopter valued at minus one. Minus one is considered the optimum starting point for the majority of SLR users with normal vision. The combination of the camera’s viewfinder components and a clear (standard) eyepiece form a virtual image of a subject on the camera’s focusing screen that is the approximate equivalent of a viewing distance of one meter.
Each Nikon eyepiece diopter incorporates a numerical value, represented by a minus value (near-sighted) or a plus value (farsighted) number, enabling you to select the appropriate diopter for your vision and your camera model. The eyepiece’s diopter value is, when combined with the viewfinder’s minus one value, the end-result value. No combination of the camera’s base value of minus one and a given accessory diopter’s value is required to arrive at the final desired value. In other words, if you require a diopter of plus 3, simply add a plus 3 diopter to your camera.
Neutral correction eyepieces do not replace the supplied standard eyepiece. The use of a neutral correction eyepiece will change the diopter value of the camera from minus one to zero.
To determine which Nikon diopter value is best suited for you, visit your ophthalmologist, optometrist or dispensing optician. Ask them to determine your diopter from (your corrective prescription) when viewing an object at distance of approximately one meter. Base your selection on this diopter value.
Some Nikon SLR Cameras have built-in adjustable eyepiece correction. Please check your instruction manual to see if additional threaded Nikon eyepiece diopters can be combined with your camera’s built-in diopter control. For cameras with built-in diopter control, use additional Nikon eyepiece diopters only if your vision dictates that optimum viewfinder sharpness cannot be achieved with the built-in diopter adjustment control.
Select camera models will accept eyepieces from multiple eyepiece families.
