• High-quality Sigma UV Filter blocks the invisible UV component of light from the sky
• Ideal for photography in high altitudes, by the sea and in regions with very clean air
• Pictures gain brilliance
• Elimination of the unwanted blue cast
• Protection for the front element of your lens

This high-quality Sigma UV Filter blocks the invisible UV component of light from the sky, which can cause blur and to which many color films react with a blue cast. UV Filters are ideal for photography in high altitudes (in the mountains), by the sea and in regions with very clean air. The pictures gain brilliance and disturbing blue casts are avoided. Because the glass is colorless, color rendition is not altered, aside from the elimination of the unwanted blue cast, and no increase in exposure is required. The colorless glass also makes a UV Filter very suitable as protection for the front element of your lens against dust, flying sand, sea water spray and the like, and it can be kept on the lens at all times. It is recommended for color and black & white film, as well as digital photography. Multi-Layer Coating for Superior Protection: Sigma has treated this filter with a multi-layer coating process, which, in addition to its UV-blocking qualities, makes these filters especially scratch-resistant. This coating does not affect the optic characteristics of the filter, but significantly optimizes the protective effects.

The ExpoDisc can be used on-the-fly to set a white balance in-camera when shooting JPEG, or later in post production when shooting RAW. Using an ExpoDisc to set a custom white balance results in consistently balanced color and eliminates many of the yellow, red and blue color casts commonly seen in digital photography. The ExpoDisc is easy to use. Setting a white balance with the ExpoDisc eliminates many of the inconsistencies and inconveniences associated with using white balance cards and targets, including unwieldy size, unwanted reflectivity, improper angling, and shadows. To set a white balance with an ExpoDisc, simply take a photograph of the light source (incident light) through the ExpoDisc, then follow your camera's instructions to set the camera's custom white balance. Because the ExpoDisc is calibrated for an 18% light transmission, you can also use it as a reference tool for manually determining proper exposure. The ExpoDisc is available in a variety of sizes to fit most popular lenses. The ExpoDisc does not thread into the lens; instead, its quick mount design can be pushed-on and popped-off to facilitate a quick white balance.

The "Double Stacked" Coronado SolarMax II Solar Telescope is a beautiful instrument that sports polished brass and black finishes as well as precisely crafted tuning knobs. When you purchase a "Double Stacked" Coronado SolarMax 60 II Solar Telescope your package includes:

Coronado Hard Carrying Case
Life Time Tech Support from High Point Scientific

The "double stacked" Coronado SolarMax II is a serious instrument built for someone looking to see the finest areas of detail on our sun. Prominences, flares, filaments and ever changing surface areas of the sun will all be brought to you in high def with the SolarMax.

So why is a "Double Stacked" solar telescope better then a traditional solar telescope? The simple answer is that you get significantly enhanced optical resolution with the "double stacked" version.

Coronado has enhanced the "double stacked" SolarMax 60 by placing an additional filter etalon at the front of the scope. Now there are two etalons present, one internally with the new RichView tuning system and one at the front of the scope with the T-Max tuning system.

"Double Stacking" the etalons improves the scopes resolution by reducing the already narrow <.7 angstrom bandpass to an even narrower <.5 angstrom bandpass. With this set up, the enhanced resolution and contrast will offer a view of the sun that is absolutely stunning.

The "double stacked" system works the same as a non "double stacked" system, the only difference is that now it's a three part system. The telescope body incorporates a tunable sub-aperture etalon in its body as well as a removable etalon on the front of the scope. These tunable etalons works in conjunction with a 15mm blocking filter situated in the solar telescopes 1.25" star diagonal. Together these elements produce a < .5 Angstrom passband which yields an optimal balance of prominence and surface detail.

The Imaging Source DFK 21AU618.AS Color USB Astronomy Camera with IR Cut Filter, 640x480 Pixel Resolution, C/CS Mount Reviews

The Imaging Source DFK 21AU618.AS Color USB Astronomy Camera with IR Cut Filter, 640x480 Pixel Resolution, C/CS Mount

• Color Interpolation: For visualization applications, it does not make sense to view the RAW image stream from the CCD chip. It must be interpolated, before it may be viewed or saved in common formats. IC Capture.AS perform color interpolation, thus reducing the load on the DFK 21AU618.AS's processor
• IR Cut Filter As Standard: Unlike the human eye, CCD chips are sensitive to near infrared light (wavelengths over 700 nm). The DFK 21AU618.AS ships with an IR cut filter as standard and is thus suited to applications in which these wavelengths would lead to interference or undesirable results
• High Speed Data Transfer Via USB: In order to transfer the vast amount of data created by the stream of uncompressed and lossless color images to the host PC, you need a very high speed bus. Hence, the DFK 21AU618.AS is fitted with a fast USB connector

The Imaging Source DFK 21AU618.AS Color USB Astronomy Camera is ideally suited to color astrophotography, in which very fast image sequences should be captured. The camera ships with IC Capture.AS, a comprehensive software package with which you can capture lossless and uncompressed images sequences and write them to disk as AVI files, or as a series of singular bitmaps.The DFK 21AU618.AS ships with the color Sony ICX618AQA progressive scan CCD chip. With its 1/4" format, the CCD chip produces a resolution of 640 x 480 pixels. Even at very long exposure times - up to 60 minutes exposure are possible - noise is minimal. Thanks to this extremely high quality, the Sony ICX618AQA CCD chip is also often used in other scientific, industrial and medical image processing applications.

• 2" Moon filter with metal filter cell construction threads directly into the barrel of a 2" telescope eyepiece
• Especially useful for large aperture telescopes through which the bright Moon surface can be overwhelming
• Transmits just 13% of the incoming light to your eye, enhancing your view
• Neutral filter will not alter the natural color of the Moon in your views

The Moon's disk, even at partial phases, is intensely bright with reflected sunlight. The glare washes out most of the craters, rilles, and other surface details from view. Our Moon Filter reduces the glare, allowing transmission of only 13% of the reflected light. Not only will you see more surface features, but you can study them in greater comfort. The filter reduces irradiation, which is the distortion at the boundary between light and dark areas, such as along the lunar terminator. The Orion Moon Filter is especially useful to owners of large-aperture scopes, in which the Moon's brightness can be overwhelming. It uniformly reduces light over the entire visible spectrum.
