Q: 1. Does this zoom attach directly to a t-ring?

A: No it does not. It slides into a 1.25" eyepiece sleeve of a telescope.

Q: 2. 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.

Q: 3. Will this work on a Celestron regal m2 100ed?

Q: 4. is this eyepiece good for long range birdwatching?

A: I use mine for astronomy with telescopes. But I think 20mm is going to be too wide for most long range birdwatching. For birdwatching I use a Swarovski 95mm spotting scope which has magnifications of 30x - 70x. This 20mm eyepiece only has a magnification of 31x with a 100mm scope. So I'd recommend a much shorter focal-length eyepiece than 20mm. Shorter focal-length eyepieces give greater magnification. So a 10mm might be better for long-range birdwatching. These eyepieces are very nice on telescopes. I assume they're very nice on spotting scopes too.
