Using a lunar or planetary filter while looking for the planets or the Moon via a telescope increases the contrast and brings out more details. They do this by improving the visibility of surface details, reducing glare, and blocking light at specific wavelengths. The two available filters are variable polishing and neutral density (ND). Planetary filters made of Wratten-colored glass intensify the sight of some planetary features by filtering light at particular wavelengths. Using the following data, users may determine the ideal solar filter for the telescope.At the chosen wavelengths, the bands of Jupiter's clouds, Saturn's ring divisions, and Mars' dusty plains are sharpened. By boosting clarity and comfort, these filters are useful tools. However, they also have the ability to transform mundane telescope views into atmospheric compositions with texture that appear nearly within grasp.

Celestron 1.25" Lunar and Planetary Color Filter Set
Astronomers may get a new view of the moon and planets with this Celestron pair of 1.25 planetary filters. The filters consist of a neutral density filter #ND-96-0.3 with 50% transmission, an orange filter #21 and a light blue filter #80A from Wratten. Users can use these filters to magnify planetary and lunar details with any 1.25 eyepiece. The filters are mounted in a black anodized aluminum cell with threading on both sides, allowing stacking and adjusting the transmission percentage. The filters are protected against reflections, ghosting, and scratches, and come with a plastic case for safe storage.
Baader Red 610 nm Longpass 1.25" Filter
Baader Color Filters provide maximum brightness with no reflections, ghosting, or stray light. Each filter is finely polished to within 30 seconds of arc and coated with 7 layers of MC coatings to ensure an image free of false reflections. The 2 mm thick glass allows for easy insertion into the optical path. Stackable filter cells with male and female threads enable combination for enhanced performance. These filters eliminate ghost images and have striae-free substrates, achieving high transmissions of up to 98% for long-pass filters and 70% for band-pass filters, resulting in maximum contrast and detail isolation in planetary observations. Different coatings match the color filter curves, allowing for narrowed passbands without image degradation.
Baader Red 610 nm Longpass 2" Filter
Baader Color Filters provide maximum brightness, and each filter is polished and coated with seven layers of multi-coatings to ensure images are free from false reflections. Made from high-quality 2 mm thick glass, they are easily insertable into the optical path and feature stackable cells with male and female threads for combining filters. The striae-free substrates, unique anti-reflection multi-coatings that match the filter curve of each color, and elimination of ghost images are all features of Baader filters. These coatings maximize transmission and minimize reflections. Band-pass filters (Green, Blue, Dark Blue) obtain 70% efficiency, but long-pass filters (Red, Orange, Yellow) attain up to 98%. Because of their built-in spectral integrity maintainer, users can stack them to create smaller passbands and use them in a variety of ways with other Baader filters.
iOptron Green Moon 1.25" Filter
The transmission efficiency of this iOptron dark green filter is 24%. Dim the Moon's light so that any telescope can see its smallest features. Using a moon filter with a telescope allows one to see the moon with less glare, irradiation, and brightness. It also makes the differences in lunar albedo features stand out more. The barrel of most 1.25-inch eyepieces is a perfect fit for the iOptron green moon filter. .Using the iOptron Green Moon Filter with bright planets like Venus, Mars' polar ice caps, and Jupiter's red and bluish atmospheric regions becomes much easier with a larger aperture telescope (8" or larger). For the most part, 1.25-inch eyepieces will work with the typical M28.5x0.6 filter thread.
Baader Planetarium 2" ND 1.8 Neutral Density Filter
To reduce the brightness of highly reflective objects, use this Baader Filter. The neutral density filter with a diameter of 2" from Baader Planetarium is ND 1.8. A 2" filter cell contains this Neutral Density Filter with many coatings. The 2" Baader Planetarium Neutral Density Filter is the result of a long history of optics manufacturing coupled with cutting-edge coating technology. Modern coating techniques have been created at Baader Planetarium. When considering in high-quality Baader Neutral Density Filters, you are getting a product that performs better than the competition. This filter is contained in a 2" filter cell and features an ND 1.8 Multicoated density.
