Didymium Light Pollution Filter for Night and Astro Photography - The best gift for you and your loved ones 🎁

Estoy contento con el filtro de contaminación lumínica Didymium pues desde que lo utilizo tengo más contraste en la vía láctea,os lo recomiendo!

The Didymium Light Pollution Filter Helps remove a lot of the green airglow from your images and gives you cleaner crisper looking star images.

This filter and the optional adaptor kit mean that I have a good light pollution filter that fits all my lenses except for an ultra-wide fast one with a bulbous front element. Although I live in a rural village, this is a Bortle Class 5 location now (it used to be Bortle 4) and I have new urban connurbations within 10Km that severely impact the night sky. As much of this is from street lighting, I wonder at the public and private waste of energy to light the night sky, particularly as the UK has to import 15% of its electricity!

I have been seeking Comet C/2023 A3 Tsuchinshan-ATLAS which, for anyone living above latitude 50ºN, has been a low early evening object in our southwestern to western skies. Having found it, it certainly was not bright enough for viewing with the naked eye due to light pollution even when using any reasonable magnification. I fitted this Dydimium filter to my Sigma 70-200mm f/2.8 lens and managed several reasonable shots of it.

Obviously any filter will reduce the overall level of light reaching your camera sensor and I would suggest that you add +0.66 EV if using a full frame camera (such as my Nikon Z6ii) or +1.33 EV if using an APC-S (cropped) sensor. This avoids increasing the exposure time as that could introduce blurring of stars that were previously sharp.

I life in the middle of streetlight much streetlight! When i use this filter it seems like it works for me , see that stars are in different colours on pictures . But because some streetlights are unfortunable to close to me that light polution is not gone but gives me weird things on picture. The only thing where i buy wrong is the filter adapter that not really fit on my 70-300mm lens 55mm screw . Only on the nikor lens 35-70mm it fits on the lens. But it is a very good filter, i can say you go for it

My filter arrived while I was visiting in Honolulu Hawaii and I used the filter there testing it during the night capturing images overlooking the city from a location called Nuuanu Valley. The sky colors looked much more natural with the filter than without the filter. Amazingly, after I saw the difference, the light pollution became visible to my eyes when I viewed other night scenes. It's well worth owning such a filter. I don't know if Lightroom or Photoshop has settings to even eliminate the light pollution narrow spectrum frequencies of light. I don't know for certain but don't believe you can correct a narrow slice of the light spectrum in post production. And if it can be done, It's labor intensive and has to be done to individual images. Much time is saved using the filter and avoids needless time doing post production corrections. Indoors under flourescent lights the filter gave cleaner whites. That felt like a bonus.

However, to my surprise, the filter did not seem to have any noticeable effect with indoor photographs using a Samsung A12 cell phone camera. I suppose the cell phone adjusted images with and without the filter on.

I utilized the filter for a few night shots both indoors and outdoors. The difference is shocking. I'd suggest this for any photographer to throw in their bag. There were no signs of vignetting or abberation in the photos. I even used it during shooting of a youtube video that I linked here

Helps bring out more colours

Good morning. I purchased several items: a Nomad star tracker, a laser, a polar scope, a light for the polar scope, an equatorial wedge, a Z-bracket, a ball head, a Bahtinov mask, etc. Regarding the light pollution filter, I have only tested it once; while the build quality is good, I noticed some artifacts in my shots. As for the Bahtinov mask, it works well, but it gets stuck in the adapter ring. Generally I need more time to test all articles.
Thank you

The quality of the accessories is great. The offered combinations should be selectable…

Great quality! I use both 15-35 and 24-70 lenses so the additional step down ring was a great addition.

Tried it in a light-polluted suburb — the orange glow in the sky is noticeably reduced, colors look cleaner straight out of camera.

The Didymium Light Pollution Filter has improved the quality of my shots in astrophotography in a suburban area.

- Only one size, too large to permit use of the lens hood, big detractor. Apparently providing a huge filter size and reducing rings is the manufacturers way of saving money by only producing one filter size. I have purchased Hoya Starscape filters in the needed 72/77mm sizes for my lenses.
- Filter I received appeared to be a return, it came out of the box/case with loose fibers on the lens. Customer Service did not reply to my questions about why I was sent a returned item.
- Verdict: more fit for purpose filters can be found elsewhere

I bought the kit with all adapters. The filter is great and I have had no trouble using it on various thread sizes. It's great to only buy the one filter! I see a noticeable difference in my photos.

Very good tailored for the dslr sensors, excellent results

Well constructed filter. The addition of filter size adapters was nice.

Excellent filter ideal for controlling light pollution in various night sky locations.

I shoot most of my Milkyway photos in Joshua tree, ca and there is a visible light pollution from the nearest town. This filter helped to neutralize the pollution. It’s good to have it in your arsenal.

Definitely cuts down on light pollution. Works in most cases to reduce the amount of light pollution from almost any area. Nothings as good as a completely dark location, but this helps.

This filter has been a game changer for me. I cannot recommend it enough!
