Orion 2"-1.25" Precision Centering Adapter

The Orion 2"-1.25" Precision Centering Adapter:

It's a simple matter of fact that everyone wants to optimize their optical performance- everyone wants the very best out of their Telescope, right? This product was built on that simple theory, to do just that- optimize your telescope's performance! This high quality, highly affordable adapter precisely centers any 1.25-inch astronomy accessory in a 2-inch focuser tube. What this accomplishes, is that it accurately centers 1.25-inch accessories on the telescope's light path, improving performance of the entire optical system! This is beneficial for both astro-photography and simple stargazing, as it enhances the scopes performance all around.

Simple to Use

Now, most standard 1.25-inch adapters will use a thumbscrew to secure inserted accessories- which works, but pushes an inserted barrel off center, hampering performance. On the other hand, the Precision Centering Adapter employs a lateral compression mechanism that accurately centers the 1.25-inch accessory on the telescope's light path- enhancing performance, rather than hampering it! Once your 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.

This method has the added bonus of keeping your 1.25-inch eyepiece and accessory barrels free of scratches and dings from thumbscrews!

The Orion 2-inch to 1.25-inch Precision Centering Adapter is especially useful in telescopes with optically fast focal ratios where finding an eyepiece's "sweet spot" focus position is crucial for obtaining optimal visual results. You'll get wonderfully sharp, centered views every time- and with far less time and effort than is usually necessary!

Of further note is that the 2-inch barrel is threaded for use with Orion 2-inch visual and astrophotography filters for easy enhancements.
