    Yes I guess it is, but the nose piece is just an adaptor, no lenses in it, so removing the nose and using the 24mm in dedicated 2" mode it is still only a 24mm. You don't get the 2 for 1 advantage with the 24mm. only from the 21mm and down

    Ahh I see that now. "The 24mm Hyperion accepts Televue Dioptrx astigmatism correction lenses, but due to optical design differences, does not accept the Finetuning Rings."

    So, it looks like it depends on which fine tuning ring you have, as they offer 2, a 14 and a 28mm. https://www.optcorp.com/product.aspx...0-82-869-10493

    ... holy smokes ... pretty slick setup ...

    ... how tough are they to "reset" (for lack of a better term) while observing? ... Just to keep objects in view I already have to hussle while changing lenses ...

    ... maybe I am just dense and missing something here ... is it as easy as popping out the 1.25 to 2" adapter and reinserting??

    Yeah well you don't need the FTRs to get the two mags per EP.

    Some of the guys love the FTRs some hate 'em. I am of the latter group. They do work well and do further expand your options from a single EP but they are a PITA to fiddle with in the dark.

    Removing and replacing just the Chromed nose piece is pretty easy but adding fiddly fine threaded rings in various combinations is not so easy, especially if you drop one in the grass, or worse, cross thread one

    My opinion only

    ... I read you ... I already own about three or four moon filters for that same reason ... man I disliked changing those things from EP to EP ... though I guess someday I'll settle down and stop swapping EPs so frequently ... lol ...

    ... and from my recent experience with parfocal rings I can understand better just how much dislike one can develop with "fiddly things" in the dark ...

    Bill you've got to stop posting at the same time as me LOL

    In 1.25" mode they are very close to being parfocal. ie while the nosepiece is still fitted, either into a 1.25" or 2" diag. When you change to dedicated 2". ie longer EPFL, then a little more refocussing is needed.

    Yes in a 2" diag it is as simple as popping out the 1.25" adaptor

    Just on these EP's they are not perfect, as they do fall off a little at the edges, but you need to weigh up the price. The next step up in a similar style EP that is completely edge to edge sharp is the Vixen LVW series at at least twice the price. Also at 68° AFOV you are looking at an object in the centre and that little bit of edge loss is peripheral.

    Overall, these are one of the best value for money EP's out there.

    Exactly. I have one diag and barlow with half a VP in the diag and the other half in the barlow specifically dedicated for Lunar use. Then its just a matter changing the complete assembly and popping in any EP without going through the hassle in the dark.

    Also consider how hard it would be to change the fine tuning rings with winter mittens on. It is hard enough to swap smooth sided eyepieces under those conditions. I would not want my hands freezing to the metal rings. Under very cold conditions the threads might not even fit properly.

    Yeah Ted, that's a point I would never consider as it never gets colder than about 15°C here.
