Opinions - Antares UltraWide's & Antares W70's

Is there anyone out there who has compared the the Antares UltraWide's with the Antares W70's? Is there any difference in the EP construction and design?

John,
The ultrawides appear to be identical with the orion expanse and adorama pro-optic eyepieces. You can read a review of the expanse eyepieces on the cloudy nights reviews which has a thorough discussion of these eyepieces. Some amateurs complain about ghosting in the expanse-pro-optic-ultrawide series. My 6mm pro-optic eyepiece reveals nice color on Saturn in my 16" dob but will ghost on the edges but is ok on-axis. I like my 8.6mm 70 degree antares eyepiece which has better coatings than my 6mm pro-optic ultrawide but it appears there's variation in these coatings--don't want to re-start that discussion again!
