Colors pop, and nebulas appear more defined, which adds a layer of depth to my astrophotography that I hadn’t achieved before.

One downside I noticed was that it’s not water-resistant, so dew or unexpected weather can be problematic. A careful eye is necessary because some brighter stars might display halos. Although it’s designed for capturing nebulae, this specificity means that I have to switch filters if I want to capture other celestial objects outside the H-Alpha and O-III bands.

For fellow astrophotography enthusiasts looking to improve their captures in light-polluted conditions, the SVBONY SV220 provides clarity and contrast that elevate our celestial images.

K&F Clear-Night Filter

When I added the K&F Concept 77mm Clear-Natural Night Filter to my astrophotography gear, the difference in my photos was undeniable. Instead of washed-out skies, I could capture the contrast and color of celestial bodies with much greater clarity.

Light pollution is a persistent problem for night photographers, and I can confirm that this filter mitigates the yellowish tint from older street lights effectively. However, its performance can vary under modern LED lighting, which is something to keep in mind.

Handling the filter, it feels solid—thanks to its waterproof, scratch-resistant coating and high-quality optical glass. The ultra-slim design complements my wide-angle lens especially well, preventing any vignetting at the corners. The nano-coating has remained intact even after multiple night sessions, and cleaning it is a breeze, which is a huge plus in the field.

Its price point might make you hesitant, but if you’re passionate about capturing the night sky in all its glory, this filter proves its worth. The peace of mind I get knowing my shots will have minimum light pollution interference is invaluable.

Celticbird UHC Filter

Upon first use, the difference was clear: the Celticbird UHC Filter excised much of the urban glow that had previously plagued my night sky observations. It effortlessly screwed on my 1.25″ eyepiece, fitting as though it was an original part of my setup. The view through my lens offered a darker sky background, providing a stark contrast against the luminous tendrils of the Orion Nebula.

Long exposure astrophotography, which was initially a challenge in my light-drenched suburbs, became a more fruitful endeavor. The nebulae’s details popped thanks to this filter’s prowess in isolating the wavelengths necessary for a crisper image. Even though the city lights continued their incessant glow, my photographs could now mitigate their effects to a degree I hadn’t achieved before.

It’s important to note, while this filter serves as an impressive ally against light pollution, it can overzealously dampen the brightness of celestial objects. I had to adjust my camera settings to compensate, but once I found the sweet spot, the images captured with the Celticbird UHC Filter provided me with a much-improved representation of the night sky. Despite this, its performance in already dark environments was somewhat redundant; the contrasts are inherently optimal away from urban light interference.
