    Q: 1. Does it work with a Regal Scope? In my case it is about Celestron Regal 80 ED.THANKS!

    A: Yes, the Regal 80 range spotting scope works with all standard 1.25 eye pieces.

    Q: 2. i have a range of spotting scopes and have just bought a televue 85 scope i want to see the birds clearly that my 82 leica 65 leica and 65 vanguard can't at long range so this eyepiece only gives me the same as them am i correct in that ?

    A: Well it depends on the Focal Length of your scope. That is what determines the power of this eyepiece technically. You take the Focal Length of your Scope and divide it by the Millimeter of the Eyepiece.

    Q: 3. Durability and practicality ?

    A: The SMC XF 6.5-19.5 eyepiece is very well made, with high quality optics. I have used my scope in rain and fog without any problems. The actual scope is some kind of durable plastic construction which has held up, especially with the case that allows you to open the front and back and leave the case on for added protection. My ONLY con is the eye relief is real short, I wish I had a little more space, but that being said the view is crystal clear, bright, and detailed. Hope this helps in your decision.Note: the original one I had was stolen in a home robbery and covered by insurance. I could have bought any other brand, and I re-chose getting the Pentax again.
