SVBONY Ultra High Contrast Filter

Basically, it works by darkening the background so you can see more nebulosity that would otherwise be too faint.
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

See Some Small Planetary Nebulae Detail

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.

Multi-coated Glass with an lon-assisted Deposition Technology

Barrel diameter: 2'' simply attach to eyepiece-cased in a sturdy transparent case

Effective protection and easy to carry

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 .
This kind of packaging with foam effectively protects the integrity of the product during transportation, and at the same time, it has a shell for easy storage and is not easy to be damaged and dust.
