Basically, they're a classic ortho, but one (or more?) of the lenses is coated with a bandpass filter to improve contrast for planetary and lunar viewing (apparently with some slight blue-green color alteration).
UO, ITE, and Sirius optics (partners in this project) are touting them as the best planetary EP ever.
Anyone know about these, or ordered any yet? They will be (are) available in 9mm, 12mm, and 18mm. Cost is around $100 or $120.
If they're not available on-line yet, I do believe they ARE available via order-form from UO (and probably from ITE and Sirius, too). I received an order form with the brochure that UO sent me.
I was planning to order a 9mm immediately, but I think I'll hold off until I hear some feedback. I'm trying to get some $$ back these days from EP overspending, so spending another $120 on a new EP is counterproductive to this goal. Also, I'm a little wary about the color alteration that supposedly accompanies this design. Depending on how noticeable/dramatic it is, I may not be interested, even if the contrast does significantly improve.
have fun!!

Tom...yes, my vacation was great...and as for the filtered aspect of these EPs, I don't think you should compare them with using other screw-on color filters. First, I don't think these will alter color or reduce light transmission like your classic color filter does. Secondly, I think these filter-coatings are optically superior in many ways to a screw-on glass filter. And finally, this setup would obviously be much more convenient to use than screwing on a separate filter.
Bill...yes, I think they're just 'starting off' with these focal lengths. And keep in mind that for many scopes (e.g., with >1500 focal length), 9mm or 12mm IS a planetary focal length. For me, 9mm with 2x Barlow gives 222x in my 8" Newtonian (1000mm focal length). Perfect.

Wonder if this means we'll see a price drop on new and used UO HD orthos? Those work spendidly on some DSOs as well as planets. Anybody wanna unload a 9mm or 18mm HD ortho at 50% off based on the idea that they can't be as good as these "new & improved ones"???
Obviousely not I have been ready to grab a 18mm UO (hd/or not) off astromart but havn't found anyone parting with one... I am almost to the point of buying an eyepiece new
