Applications 9 & 12mm centering eyepiece
The Meade 9mm crosshair eyepiece has adjustable lighting and is often used for aligning a mount (using the drift method) and can also be used as tracking eyepiece in astrophotography. Also included: a fixed crosshair in the eyepiece so you can see a red crosshair against a dark sky

Precise crosshair with rubber eyecup

The crosshair is a double crossline with two concentric circles. Sharp and powerful images of the four elements, multi-coated, Plössl optical system are completed with a rubber eyecup (foldable for eyeglass wearers) preventing light scattering. The upper section of the eyepiece lens turns on fine thread for precise diopter adjustment.Note: We recommend that you use this eyepiece in combination with Merade filter sets, which can be found on our website.

About the 25mm wireless eyepiece
Because of the relatively small dimensions of the microchips used in CCD imaging systems, it can be difficult to compose the astronomical image (confirming the object orientation and relative size compared to the chip orientation and dimensions and centering the object on the chip) , this is particularly true for the faint and diffuse objects. This task is made easier with the Meade 25mm Plössl centering eyepiece. The eyepiece can be used in two ways:

1. by placing it in the eyepiece holder of the telescope, and then replace the centering eyepiece by the CCD camera
2. in conjunction with a flip mirror system.

Eyepiece with red LED light

The eyepiece gives an evenly lit, red LED light that provides framing of all popular CCD chip sizes, including all Meade Pictor Series CCD imagers plus the ST-5 to the ST-8. A lockable spacer ring fixes the focus of the eyepiece, which allows the focus of the eyepiece and the CCD imager to be made precisely parfocal.Note: We recommend that you use this eyepiece in combination with the flip-mirror system, which can be found on our website.
