Felt my Meade LX70 120mm f/8 refractor wanted some attention. So I used it for the test comparisons. Tested it against the GSO 25mm
plossl and Svbony 6mm on Orion. At 41 magnification the AgenaAstro showed the trapezium stars just as sharp as the GSO 25mm. Zoomed in to 125 magnification and each trapezium star showed an airy disk. Using a barlow at 166 magnification the AgenaAstro showed four airy
disk again, and just as sharp as the Svbony 6mm. The GSO 25mm is sharp out to over 90 percent to the edge. The Agenaastro is sharp out to
about 80 percent to the edge. Eighty percent is not bad since I will be using it for high mag on the Moon, planets, and star splitting. Zooming in and out is really cool, but I had to refocus a little once at the magnification desired. The eye relief is good at all magnifications. The lowest field of view is 40 degrees, which is not bad at all. The eyepiece is mechanically very smooth. Using this zoom eyepiece on the Moon with my 150mm f/8 is going to be a real pleasure.

Thanks for the review. Do you think that this EP would work well in an ES ar102?

The scope I used and my Yard Canon have a f/8 focal ratio. The ES ar102 is a f/6.5 ratio. I think it should work with your scope. Buy this Astromania which is shipped by Amazon. I am certain it is the same zoom eyepiece/made at the same factory. If you do not like, no big deal. Amazon pays for return shipping. Amazon also pays for outbound shipping if the order is over $25. I always check with Walmart and Amazon first, but neither had the 56mm plossl that I wanted. So ordered the plossl from AgenaAstro with the zoom eyepiece. Just setup an Amazon acct. If there is a problem, no need to contact Amazon. You can print out a UPS label from your acct.

Thanks much for the info.
