This is the eyepiece that now "lives" on my telescope 90% of the time. It needs a little bit of re-focus as you change from wide-angle to full zoom, and the FoV narrows down a bit when zoomed out longer than about 15 mm (50 degrees over 7.5 to 15 mm say, then gradually reducing to about 40 degrees at 22.5 mm), but it's really handy as a general workhorse eyepiece.

Thanks. Yes, I forgot about the zooms. I too have a Seben zoom, but it's the 8-24mm one, which was certainly much better than a previous 7-21mm zoom I also have.
I must admit to being a bit weird with zoom eyepieces, I don't use them much, but when I eventually put them on a telescope they actually stay there quite a while.
If you are so happy with yours, and I am very happy with mine, I keep wondering what Seben's expensive zoom eyepiece is like (or which other seller's zoom it is the same as, and how much are they charging for the same thing?).
Cheers,
