SVBONYSVBONY SV115 Telescope Filter O-III Filter Narrowband Cuts Light Pollution Filter for Astronomy Telescope (1.25 inch)
Main highlights- The filter made from high-grade glass with dichroic interference and antireflection coatings;not only useful at light-polluted sites; the contrast is also increased at dark sky sites;it can be used with all 1.25" eyepieces
- The O-III filter completely blocks virtually all other visible wavelengths of light so views of nebulas are optimized;increases contrast through selective filtration-Anti-reflection coated to prevent glaring and ghosting
- The 1.25" O-III filter useful for large aperture telescopes through which the light of the Moon can be extremely overwhelming. Allowing just for the Double Ionized Oxygen lines between 495.9nm to 500.7nm to pass through at 90%
- Narrowband filter do not eliminate the effects of light pollution or increase the object’s brightness;in many cases, they increase the contrast between nebula and night sky, not brightening the nebula
- Astrophotographic;The filter enhances contrast during visual observation of gaseous and planetary nebulae in all sky conditions; 1.25" filter allows high-contrast imaging even in areas with strong light pollution

AstromaniaAstromania 2" Moon/Skyglow Filter
Main highlights- Standard 2 Inch Filter Thread: The 2 inch Moon and Skyglow Filter is simply screwed into the eyepiece thread; the filter will fit all standard sized 2inch eyepieces and accessories; it is threaded on both sides for stacking with other filters
- Premium Image Quality: Reducing the brightness of the moon and improving contrast and surface detail; reduces glare and improves definition; this can be useful when viewing the sky in areas where there is a lot of light pollution
- More Than Normal Moon Filter: This premium Moon and Skyglow Filter is much higher quality than similar products; a particularly disruptive factor during observation is the illumination of street lights
- Exquisite Detailed Design: Premium material with exquisite craftsmanship, sturdy and solid for long-lasting use; this filter is mounted in a nicely anodized housing and comes with a filter case to better protect the filter; easy to carry around
- Excellent Moon Filter: 2-inch Moon and Skyglow Filter is a multi-bandpass filter transmitting a high percentage of light in the visual spectrum; the Skyglow Filter absorbs more light at longer wavelengths and therefore increases viewing contrast
