Celestron’s Moon Filter is an economical eyepiece filter for reducing the brightness of the Moon and improving contrast, so greater detail can be observed on the lunar surface.
High quality ND96 1.25" moon filter by Rother Valley Optics is ideal for observing the moon between half phase and full moon. This filter cuts down the light making the moon far more comfortable to view whilst increasing contrast.
High quality RVO IR block filter 1.25". Ideal for use with webcams when doing planetary imaging. They are best used with imaging cameras that have low sensitivity in the IR region such as webcams.
The Neutral Density Moon Filter attaches to a 1.25” eyepiece to lower the amount of light entering the eyepiece by 87%. The Moon is one of the most viewed objects in the sky, but you shouldn’t be deprived of its features due to brightness.
These contrast-enhancing anodized aluminium, optical glass filters are designed to block out the wavelengths of light emitted by mercury-vapour light and other common causes of light pollution, whilst providing higher transmission at critical hydrogen-alpha and hydrogen-beta lines than competing filters.
High quality ND96 2" moon filter by Rother Valley Optics is ideal for observing the moon between half phase and full moon. This filter cuts down the light making the moon far more comfortable to view whilst increasing contrast.
Luminance/Infrared cut-off filters are usually being used with web cameras, color CMOS and CCD cameras to produce better quality images, as these are quite sensitive to infrared (heat) radiation of light.
These high quality anodized aluminium, optical glass variable polarising filters reduce the amount of light entering your eyepiece. You can progressively dim the view when observing a bright object, such as the Moon or certain planets
This 1.25in filter consists of two joined polarized filters that provide continuously from about 2% to 40% as the rotating filter is adjusted. Great for lunar viewing without ruining your dark adaptation from staring at a bright image.
A small but very useful adaptor. If you have any Astronomik clip filter, this handy adaptor allows you to use these on any 2" eyepiece using the filter thread on the bottom.
When you want to selectively reduce the brightness of celestial objects for a customized view, the Variable Polarizing Filter is the perfect choice. Unlike regular Moon Filters and Neutral Density Filters, the level of brightness can be reduced to just 1% or as much as 40%.
The Optolong Moon & Skyglow filter is designed to darken the background sky by blocking light transmission from skyglow 589nm and many street light emissions from artificial light.
Comprises 4 x high quality glass colour filters. Yellow, Red, Green & Moon/Neutral Density Filters included. These filters will fit most internally-threaded eyepiece barrels of 1.25"/31.7mm format. Supplied in attractive foam-lined plastic screw top storage case.
