Adam,
You have already written an excellent first hand review of this premium eyepiece.
I've been only at Stargazing for two years. Fortunately I bought a 19mm Panoptic early very early (from an IIS member). It helped that I had read Backyard Astronomer's Guide cover to cover.
One good night with that EP and I was hooked! So nearly 2 years later my EP kit contains 19, 24, 27mm Panoptics plus 12 & 17mm Nagler T4s. Recently added 2X and 4X Powermates for gear changing views depending on conditions.
See reviews elsewhere - these are lifetime investments. You may upgrade your scope/s, but you will keep these EPs (if you have a champaigne income then some Ethos EPs may be tempting.)
