Celestron UHC/LPR Filter 1.25 inch

Celestron UHC/LPR Filter – More Contrast for Your Deep-Sky Observation

The Celestron UHC/LPR filter is a special filter for visual observation of nebulae and galaxies. It is designed to improve the visibility of deep-sky objects by suppressing light pollution.

• The filter significantly increases the contrast of emission nebulae and planetary nebulae by filtering out unwanted stray light.
• Thanks to its compact design with a 1.25-inch diameter, it fits into most standard eyepieces and observation accessories.
• The high-quality coating ensures high light transmission in the relevant wavelength range and minimizes reflections.
• With a focal length of 0 mm and a magnification of 0×, it is designed as a pure accessory and does not affect the optical parameters of the telescope.
• The 24-month manufacturer's warranty provides long-term security for your investment in astronomy equipment.

What sets the Celestron UHC/LPR filter apart

The filter is specifically optimized for observing night-sky objects affected by artificial light sources. It effectively blocks the typical wavelengths of sodium vapor and mercury vapor lamps, which are widespread in cities and settlements. As a result, nebulae and galaxies appear significantly more contrasted and detailed.

Ideal for...

This filter is ideal for amateur astronomers who wish to observe in areas with moderate to high light pollution. It is particularly suitable for beginners and advanced users who want to improve their observations of emission and planetary nebulae without having to perform a costly telescope upgrade.

How to use the Celestron UHC/LPR filter

Simply screw the filter into the 1.25-inch eyepiece of your telescope. Make sure the filter is firmly seated, but do not overtighten it. Then point your telescope at a deep-sky object and enjoy the improved contrast. The filter can also be used with a Barlow lens if necessary.
