Photoscape x bright one spot5/31/2023 Prime examples are filters for Sulfur-II, Hydrogen-alpha, and Oxygen-III, often abbreviated to SHO. Perhaps the biggest benefit of Mono is that you can use special narrowband filters that only allow very specific wavelengths of light through to your sensor. Mono also lets you shoot Luminance data, which adds to image quality and creates LRGB images (Luminance + RGB). OSC cameras inefficiently record lots of green light (simulating how our eyes work), but there’s not that much green in space. In principle you can get a higher quality final image in the end. The author’s OSC astrophotography rig, which he uses from the light-polluted city center of Bristol, UK. But the times, they are a-changin’, and now OSC has a secret weapon: dual-band filters. Until quite recently, Mono was really the only valid choice for city-based astroimagers. Your best bet is to aim for very long exposure times to help combat light pollution. Getting good images of them from a city is a real challenge, regardless of whether you’re using an OSC or Mono camera. ![]() To get color images from them, you need to take photos with a red, a green, and a blue filter in front of your sensor, then digitally combine them all to make an RGB image.
