Struggling to see deep-sky objects from the city? This Celestron filter duo is a game-changer! The 1.25-inch UHC/LPR filter cuts out annoying light pollution from streetlights (like mercury and sodium vapor), making nebula details pop with way better contrast. It lets over 97% of the good light through, so your views stay bright. Perfect for scopes from 4\ to 11\.
The second filter is a Narrowband Oxygen III (OIII) filter. This one is super specialized—it only lets through the specific blue-green light (at 496nm and 501nm) that planetary and emission nebulae give off. The result? Crazy contrast against a black sky, making faint objects like the Veil or Ring Nebula look incredible.
Both filters feature ultra-hard, plasma-assisted coatings that are super durable and scratch-resistant. They screw right into your 1.25-inch eyepieces. The OIII filter is made in China, measures about 3x3x1 inches, and weighs around 1 pound.
Whether you're imaging or just visual observing, this pair will transform your views of nebulae from both light-polluted backyards and dark sky sites. Get ready to see details you've been missing!
