Meade's Herschel Wedge can be used with refractor telescopes up to 152mm. A Herschel Wedge takes the place of a standard diagonal. Unlike front-mounted white light solar filters, this diagonal is mounted on the back end of the telescope. A Herschel Solar Wedge produces white light views of the Sun, however, the image will be sharper and of higher contrast than that of typical solar filters. The reason for the extra sharpness and contrast is due to the placement of the filter. Since the Herschel Wedge is mounted in place just before the eyepiece it can eliminate any reflections before the image reaches your eye.

Meade's 2" Solar White Light Herschel Wedge comes with a 2" barrel on both the telescope and eyepiece side. A 2"-1.25" adapter is included so you can use both 2" and 1.25" eyepieces for solar viewing. The Wedge includes both a multi-coated variable polarizing ND3 filter and a removable multi-coated circular polarizing filter. A hard case is also included so that you can store your Herschel Wedge safely while not in use.
