1.25 Inch UHC Deep Sky Filters Ultra High Contrast for Telescope Eyepiece lens:
If you're not sure if a light pollution filter will benefit you or not (and it probably will), this SVBONY UHC Filter is a relatively inexpensive way to find out. 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.
SVBONY Light Pollution Reduction FilterSVBONY Ultra high Contrast Filter
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
Brand New SVBONY 1.25" 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
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
Excelent Light Pollution FilterThe filters of SVBONY are not designed for sun observationDo not look at the sun with SVBONY filterIt seems well suited for photographing emission nebulae. Galaxies, clusters and solar system objects
boosts contrast by blocking some frequencies of light (commonly used by street lights) and letting through light in the wavelengths emitted by most nebulae
