5 Of The Best DSLR Filters For Astrophotography – SlashGear

A major issue astrophotographers must deal with is the skewed coloring of nighttime images, often due to light pollution. Sodium and mercury-vapor streetlights and other powerful lights from urban areas will cast your photos of the night sky with unwanted shades of green, brown, and yellow. The Hoya Starscape will help reduce the skyglow in those yellower shades and give your images a cooler, more pleasing, and natural look. Additionally, it will increase the contrast between the sky and the stars you’re capturing, for a cleaner, more detailed image. Even better, you have a range of options for your lenses, with the Starscape’s circular lens filters coming in 9mm, 52mm, 55mm, 58mm, 62mm, 67mm, 72mm, 77mm, 82mm, and 100mm.

However, it’s a shame there’s no 150mm option, and the only filter insert size is limited to 100mm. Another downside to the filter is that it darkens the image by a half-stop, which is not ideal considering you want all the light you can get in astrophotography. Hoya, a Japan-based brand of optical equipment, has been trusted for decades, and its Starscape is one of the best light pollution filters on the market. It’s also reasonably priced, with the ​​55mm lens normally priced at Amazon for $44, and currently available for $33.
