Best of all, once you have it you'll probably feel no need to pick up a pricier one since this one will likely meet all of your needs. The SVBONY ultra high contrast filter/UHC telescope filter is designed to improve the image contrast of nebulae and other deep-sky objects UHC filters or light pollution reduction filters are designed to selectively reduce the transmission of certain wavelengths of light;especially those produced by artificial light Due to its ability to produce exceptionally sharp and clear images;this filter is considered one of the most popular astronomy accessories;it can be used not only for celestial observations but also for astrophotography Does a good job of cutting out light pollution The sky is much more black than without it. However it does cause a halo. If you turn down the exposure it does go away or weakens up enough not to notice The difference is even noticiable from looking through it without a telescope Works great and increases the contrast so I can see more in the nighttime sky from where I live If no light difference The reason may be that the spectrum of the light source and the spectrum of the light filter have overlapping conflicts;The reason may be that the spectrum of the light source and the spectrum of the light filter have overlapping conflicts;You can change the environment to test if there is See Some Small Planetary Nebulae Detail Basically, it works by darkening the background so you can see more nebulosity that would otherwise be too faint This filter has allowed one to actually see some small planetary nebulae that would otherwise be too washed out by the background to be seen, and I'm able to see more detail and more of the dimmer fringe of larger nebulae like the Orion Nebula, the Dumbbell Nebula, and the Lagoon Nebula. It helps with finding the little planetary nebulae because it dims everything but the nebula, i.e. you can look at the same spot with and without the filter, and with the filter in place the stars are dimmed somewhat but the nebula isn't. The nebula is the dot that doesn't get dimmer when you thread in the filter. It works well at both low and high powers, too. Suitable for Many Telescope The threads are well made and it threads perfectly into every eyepiece . It came in a nice flip-open snap-closed plastic case with a foam insert, and even in the dark it's easy to take in and out of the case without touching the glass. it works with any telescope, in the 60mm refractor and 76mm reflector as it does in the 130mm reflector. It's a noticeable improvement and helps you see things Features of the UHC Filter : Sky background is darker for observations of deep-sky objects This filter is perfect for observation of faint and low-contrast deep-sky objects. These features make it perfect for observing nebulae and other deep-sky objects Barrel diameter: 1.25'' simply attach to eyepiece-cased in a sturdy transparent case Significantly reduces light pollution, great for city and suburban observation Pls note: the filters of SVBONY are not designed for sun observation. Do not look at the sun with SVBONY filter. You would be blind if you fail to observe the warning. Package Includes SVBONY 1.25 inch UHC Filter Sturdy Plastic Case about svbony
