The 1.25" Variable Universal Adapters allow attachment of a body to reflector and refractor telescopes for either -focus or telescope eyepiece-projection photography. The adapter's 1.25" nosepiece slides into the telescope's eyepiece holder just like an eyepiece. This Variable Universal Adapter is composed of detachable parts: a -focus adapter (or "T-adapter") for -focus photography, and a fixed-length or variable extension tube for eyepiece-projection photography. A thumbscrew in the extension tube holds the telescope eyepiece in place. This combination of -focus and eyepiece-projection adapter has a sliding barrel design that allows variable projection distances. This allows for slight changes in magnification without swapping telescope eyepieces when performing eyepiece-projection photography. Fits reflector and refractor telescopes with 1.25" eyepiece holders. The Variable Projection Adapter allows for a continuous range of projection magnifications during eyepiece-projection photography for telescopes with a 1.25" focuser.The machined sliding-cell assembly can be fixed at any position along its length and is held in position via a thumbscrew. The resulting effective focal ratio is then determined by the sliding adjustment and eyepiece used. A T-ring specific to your D/SLR is required to connect your to this adapter (not included).
Simple to Use; also Ideal for Beginners: Provides a secure connection between your SLR and your telescope; it allows you to immediately start taking focal plane or eyepiece projection images
Premium Material Design: Anodized aluminum construction is sturdy and solid; withstand daily wear over long period time of use; extend product's service life
34mm Scales Value on Variable Extension: Provides more precise adjustment; achieve to adjust focal length for increasing the magnification and getting the best beautiful photos of the Moon and planets
Full Extinction Thread with Greater Load-bearing Performance: The inner wall extinction thread is fully covered which better eliminates the reflection of light during shooting; a thicker body provides greater stability
Zooming into The Night Sky: Connect this adapter to each telescope with a 1.25" eyepiece connection; you can use an eyepiece of any focal length - and you can achieve high-magnification images of lunar craters and planets - without needing to change your eyepiece
