Never tried the eyepieces that came with it though.

"The optics are made with a Schott glass positive front Crown element and a second lens element fabricated of fluorite."
I've never seen anyone mention anything about a fluorite element before on this OTA.
Also, is this basically the same OTA ( 114mm Outside diameter) as the Celestron OMNI 120 but in a shorter tube with better optics.

All three instruments in Sky-Watcher's ProED Doublet APO Refractors use the same two-element objective design. Each front Crown element is made of Schott BK-7 glass, while the back Flint element is FPL-53, two of the most advanced extra-low dispersion glasses available. Both have state-of-the-art optical multicoatings.
Overall, I found that the Sky-Watcher 120 ProED Doublet APO refractor is a solid performer. Images were sharp and contrasty with no appreciable secondary chromatic aberration evident. My only complaints, and they were minor, were finder placement and a somewhat rough focuser.

I wanted something larger than my TSA-102, and something smaller than my T0A-130 that would match my Vixen GP-DX mount. The scope performs beautifully for casual back yard observing and also for taking out to a dark site, which I did last night. I just sold my TSA-102 because of this scope, and will probably be putting my TOA up for sale also, so I can get a nice 6" refractor now.
