Eight color filters set for astronomy to match different objects. Choose the filter that corresponds to the color the object you are viewing does not have, such as Moon, Jupiter, Mars, and others. The result is enhanced contrast and improved visibility of details. Compatibility and build - Fits all standard 1.25-inch eyepieces and 1.25-inch T-Adapters; threaded on the tube for secure mounting. - Designed for use with common 1.25-inch optical accessories, enabling quick and reliable setup. Performance and benefits - Helps when observing very bright objects that can be difficult to discern without a filter. The right color filter reduces glare and enhances detail, making features easier to see through the telescope. Practical applications - Moon: use appropriate filters to bring out surface texture, craters, and mountain ranges with greater clarity. - Planets (such as Jupiter and Mars): improve contrast to reveal cloud bands on Jupiter or surface markings on Mars under suitable conditions. - Bright targets in general: suppress glare from intense objects to obtain clearer views and more defined features. Notes - The set includes eight color filters; colors include green, red, yellow, blue, and four additional filters chosen to optimize contrast for a variety of observing targets.
