Orion 52024 2-Inch to 1.25-Inch Precision Centering Adapter (Black)
We know you want the very best performance from your telescope and the Orion 2 inch to 1.25 inch Precision Centering Adapter will help! This affordable adapter precisely centers any 1.25 inch astronomy accessory in a 2 inch focuser tube. By accurately centering 1.25 inch accessories on the telescope's light path, performance of the entire optical system is improved. Using the Orion Precision Centering Adapter is beneficial for both astrophotography and visual stargazing. Whereas standard 1.25 inch adapters commonly use a thumbscrew to secure inserted accessories, which pushes an inserted barrel off-center, the Precision Centering Adapter employs a lateral compression mechanism that accurately centers the 1.25 inch accessory on the telescope's light path. Once a 1.25 inch eyepiece, collimator, camera nosepiece, or other 1.25 inch accessory is inserted, a simple clockwise rotation of the Precision Centering Adapter's knurled top ring moves two steel rollers towards the exact center of the optical axis, precisely centering the accessory and securing it in-place. Your 1.25 inch eyepiece and accessory barrels will remain free of scratches and dings from thumbscrews when you use the Precision Centering Adapter.   The Precision Centering Adapter's 2 inch barrel is threaded for use with Orion 2 inch visual and astrophotography filters for easy enhancements.
