ICE CO 82mm Slim MC LiPo Didymium Filter - Night Sky Light Pollution

Our review of the ICE CO 82mm Slim MC LiPo Didymium Broadband filter finds it aimed squarely at landscape and night sky photographers who need a subtle way to reduce light pollution without introducing color shifts. The bottom line: this filter blocks annoying skyglow while preserving the natural color balance of stars and foregrounds, and its slim 3.6mm height makes it a practical choice for wide-angle lenses where vignetting is a concern. The package includes a storage case and a double-threaded metal frame that adds mounting flexibility for hoods or stacking.

Key Features

• High quality optical glass: ensures clear, sharp detail across the frame so star points and landscape edges remain crisp.
• Nano multicoated, 16 coats: the 8 coats per side reduce reflections and increase transmission for cleaner night images.
• No color cast: blocks skyglow while preserving the overall color spectrum, so skin tones and star colors stay natural.
• Slim 3.6mm profile: designed for wide-angle use to minimize vignetting on full-frame and APS-C setups.
• Double threaded metal frame: allows additional filters or a lens hood to be mounted without compromising build quality.
• Water resistant and easy to clean: practical for fieldwork in damp or dusty conditions and simple to maintain on a shoot.

Who It's For

This filter is best for night sky photographers using wide-angle lenses who need a lightweight, slim solution to reduce urban and horizon skyglow while keeping accurate colors. Astrophotographers who shoot composite landscapes with foreground detail will appreciate the no color cast claim and the multicoating for reduced flare.

It is less relevant for photographers who rely on heavy, narrowband emission line filters for deep-sky imaging or those who need dramatic color contrast shifts; those users should look toward specialized narrowband or heavier spectral filters designed for telescope imaging.

Pros & Cons

Pros

• Effectively reduces skyglow without altering the overall color balance of the scene.
• Slim 3.6mm frame minimizes vignetting on wide-angle lenses and keeps the front element low profile.
• Durable double-threaded metal frame and included storage case make it convenient for travel and stacking.
• Nano multicoating with 16 coats lowers reflections and helps maintain contrast in night images.

Cons

• Not a substitute for narrowband filters for emission nebulae or deep-sky imaging; it is broadband and subtle by design.
• Limited to sizes specified (82mm here); users with different thread sizes will need step rings or alternative sizes.

Our Verdict

The ICE CO 82mm Slim MC LiPo Didymium filter is a smart, value-minded choice for landscape and night sky photographers who need a low-profile, broadband solution to reduce light pollution without compromising color fidelity. Its slim metal frame, heavy multicoating, and included case make it practical for field use, though astrophotographers seeking narrowband performance should consider specialty filters instead.

Frequently Asked Questions

Will this filter add a color cast to star photos?
The design and multicoating aim to block skyglow without changing the overall color spectrum, so normal star and foreground colors are preserved.

Does the slim profile prevent vignetting on wide lenses?
Yes, the 3.6mm slim height is intended to minimize vignetting on wide-angle lenses, especially on full-frame and APS-C bodies.

Can I stack other filters on top?
The double-threaded metal frame supports additional filters or a lens hood for flexible use in the field.
