Astromania 1.25'' Extendable Camera Adapter For Either Prime Focus Or Eyepiece Projection Astrophotography With Refractors Or

The Astromania 1.25'' Variable Universal Camera Adapters Allow Attachment Of A Camera Body To Reflector And Refractor Telescopes For Either Prime-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 Camera Adapter Is Composed Of Two Detachable Parts: A Prime-Focus Adapter (Or ''T-Adapter'') For Prime-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 Prime-Focus And Eyepiece-Projection Camera 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 Camera 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 Camera Is Required To Connect Your Camera To This Adapter (Not Included).
