This 1.25" modified achromatic (Kellner) eyepiece has a built-in cordless illuminator for use with any make or model telescope and/or off-axis guider. The cordless illuminator has an on/off switch with an integral brightness level control. It uses two 1.5 volt LR-44 button-type alkaline camera batteries or their equivalent (MR-44, SR-44, 357, etc.).
Batteries are included with the eyepiece, but are not guaranteed to be charged when received, as the batteries are supplied by an outside vendor and are not covered by the Meade factory warranty. It may be necessary to purchase batteries prior to use.
The eyepiece has a dual crosshair reticle. The top of the eyepiece rotates to focus the crosshairs sharply to match your eyesight.
For guiding tolerance purposes with your particular scope, you can calculate the area of sky subtended by the small central box formed by the dual crosshairs by aiming at a star near the celestial equator. Turn off the scope drive and count how many seconds it takes for the star to drift from one side of the box to the other. One second of time equals 15 arc seconds of sky.
The eyepiece has a soft turndown rubber eyecup for eyeglass use.

What I like about this product the illuminated reticle is adjustable. Great for various darkness levels when trying to center image on a alignment start. I feel this product is well made. Only time will tell if the wire connected to the reticle can withstand wear and tear. Caution: You must be mindful where the wire is at when navigating the telescope...make sure the wire does not get caught anywhere. I use a Velcro strap loosely tied around the handle on my LX 200 AFC 12" telescope doing this allows the wire to move freely. Make sure the telescope only rotates 180 degrees...if you need to rotate more unplug the unit from you power source...once the telescope is in position reconnect. Remember you are using this device in the dark...the wire can easily get wrapped around the telescope if you are not careful. You only need to use this product when you align your telescope...no noticeable drain on power.
Perfect for equatorial alignment and data measurement observations.
The illuminator quit working hours after using it. Replaced the batteries and nothing!! Had to turn around and buy the celestron eyepiece and return the meade.
Bought for doing drift alignment, but would be better for measuring sizes and splits of stars. Nice display; quality eyepiece. Works pretty well for drift alignment, but can be easily nudged "on" by accident when storing, meaning a trip to the drugsrore for more watch batteries!!
