Meade Series 4000 #11 Yellow-Green Filter Color 1.25" 07513

Color filters are an essential tool of the lunar and planetary observer, for filters permit the observation and photography of surface detail that is often virtually invisible without filtration.xFilters solve, or greatly reduce, the effects of two basic observing problems: (a) Irradiation is the fuzzying of a boundary between lighter and darker areas of the Moon or a planetary surface and can be caused either by the effects of highly contrasting light impacting the human eye or by the motion of the Earth's atmosphere, through which the observation is being made. (b) Contrast is the separation of adjacent surface regions according to their color; for example, a light green area on Mars can become mixed in the eye with an adjacent light yellow area, to the effect that the combined area appears yellow-green, unseparated into its component regions.The use of a Meade Series 4000 color filter can mean the difference between seeing small craterlets in the floor of Clavius on the Moon and not; it can mean the difference between seeing five or six whirls, festoons, and loops in Jupiter's north equatorial belt and seeing one or two; it can mean the difference between seeing the inner crepe ring of Saturn and not. Depending on atmospheric conditions on both the Earth and the planet being observed, the advantages of color filters can be anywhere from subtle to dramatic.Series 4000 filters thread into the barrels of virtually all 1.25" eyepiece brands. Meade Series 4000 filters are a large 26mm in clear aperture and are manufactured from the purest crown optical glass, dyed-in-the-mass (not "color coated"); there are no finer filters available for telescopic applications. Each filter glass is anti-reflection coated on both sides and is mounted in a machined aluminum cell with the Wratten No. of the filter marked on the side of the cell. Filters may be piggybacked, or stacked, to achieve selective filtration of the visual color spectrum. The eyepiece-with-filter can be

Celestron NexImage 5MP Solar System Imager CEL-93711

Capture high resolution 5MP planetary, lunar and solar images. Combined with the included software package, NexImage 5MP can bring out tremendous detail and produce images that will rival those taken with astronomical cameras costing hundreds more. The NexImage 5 Solar System Imager allows you to view and capture live video on your computer. The software used automatically filters out video frames affected by poor atmospheric "seeing" leaving only the clearest, sharpest frames to be aligned and stacked into one high quality image. With a 1.25" machined aluminum adapter barrel, the NexImage 5 is compatible with most any telescope.
