Handy accessory for your gadget casePros:
Good combo piece to have in your scope case or gadget bag. I got mine because the OEM of my ED Fluorite scope had discontinued their 2" T-adapter. At that time, I did not have a separate 2" to 1-1/4" eyepiece adapter, either, so....
The only downside is that the 1-1/4" eyepiece opening is smaller than a regular 2" T-adapter. Furthermore, you can get a CAMERA ADAPTER (Agena Astro has them) for a specific camera that has a wider opening to allow all the light from the scope to the camera. But for a jack-of-all-trades connector, this product is what you should expect.
