Canon 93515, 93518, 93517 manual Green

GREEN

#56 Light Green 53% T [Series 2]

Moon– Enhances lunar features. Jupiter – Increases visibility of the Great Red Spot. Useful for observing the low-contrast hues of blue and red that exist in the Jovian atmosphere. Mars – Excellent for increased contrast of Martian polar caps, low clouds and yellowish dust storms. Venus – Useful for Venusian cloud pattern studies. Reduces brightness of blue sky during daylight observing.

#58 Green 24% T [#94118-11 & Series 3]

All observing information for this filter is the same as that given for the #56 Green filter, with the exception of the following:

Saturn – Enhances white features in the Saturnian atmosphere.

Comets – Useful for observing brighter comets.

VIOLET

#47 Violet 3% T [Series 4]

Mars – Useful for detecting high clouds and haze over the Martian polar caps. Very useful during the violet clearing. Mercury – Helpful in detecting faint features. Saturn – Good for ring structure studies. Venus – Increases contrast of dark shading in upper Venusian clouds. Comets – Useful for observing brighter comets.

96ND FILTERS

#96ND 50% T – Density 0.3	[Series 3]
#96ND 25% T – Density 0.6	[#94118-15 & Series 2]
#96ND 13% T – Density 0.9	[#94118-16 & Series 1]

Moon – Excellent for reducing irradiation, glare and subject brightness. Colors are unaltered, as light is transmitted uniformly over the entire spectrum. Each model performs somewhat differently, depending on the brightness of the moon. Planets – Stacking in combination with color filters lowers transmission, but retains true color balance for specific applications. Reduces glare on brighter planets and minimizes irradiation. Binary Stars – Helpful in splitting binary stars, because it reduces glare and diffraction effects around the brighter star of the binary pair.

POLARIZING

[#94118-17 & Series 1]

Reduces reflected polarized light in the earth’s atmosphere.

Moon & Planets – Invaluable in reducing irradiation and glare. Binary Stars – Helpful in splitting binary stars, because it reduces glare and diffraction effects around the brighter star of the binary pair.
