Meade Electronic Eyepiece

This electronic eyepiece can be used with virtually any telescope to show you real-time live black and white images of the Moon, planets, stars, and daytime terrestrial objects on your television screen. Just connect the supplied cable to the yellow-colored Video-in port of your TV set, VCR, or camcorder. The Electronic Eyepiece has a 320 x 240 pixel CMOS monochrome imaging sensor. Barrels are included to allow you to fit the eyepiece into either 0.965" or 1.25" focuser sleeves. The eyepiece includes a 6 ft. cable and is powered by a (user-supplied) 9-volt battery that fits neatly inside the eyepiece housing. A built-in control permits contrast adjustment of the image. The Electronic Eyepiece is perhaps the largest-selling product of its type ever developed. Tens of thousands of Meade #902 Electronic Eyepieces are now in use in telescopes ranging from 60mm refractors to 12" Schmidt-Cassegrains

But not when it comes to locating information omitted from an instruction manual. The expected image I saw of the moon through my 9mm lens initiated the search. I should have came here first, because it would have saved me a lot of time - as would Meade mentioning somewhere on the box or in the manual that this was a 4mm eyepiece.

So now I know I need a reducer for decent lunar observation. Since they failed to mention the mm of this eyepiece, it should come as no surprise that Meade also fails to mention the use of filters with this eyepiece - neutral density or variable polarizers (which is nice to have for lunar observation), or Light Pollution/Broadband filters for deep-space observation (which is a must-have if you live in/near the city).

You may very well be able to see some deep space objects using this eyepiece with the proper filter - I have no clue yet. I was planning on purchasing filters anyway, so I'll update this review with an answer to those questions....
