Analyzing light at these specific wavelengths can teach us more about the imaged target than what can be gleaned from an RGB color image. You can also shoot an image with no filters, which you can then combine with your color data to greatly improve its signal-to-noise ratio.Īdditionally, monochrome cameras can capture images at particular regions of the spectrum, even beyond visible light, when combined with narrowband filters. With this configuration, you can shoot color pictures using red, green, and blue filters. The most versatile imaging approach is to use a monochrome sensor paired with a filter wheel. I know people with both a car and a truck, and just like them I use both approaches to create my color images. Is that a better route than using a one-shot color (OSC) camera? Well, that's like asking which is better, a car or a truck? That depends on what you want out of your vehicle. Okay fine, but monochrome cameras can produce color images, too, when paired with a filter wheel. Colored filters that revolve into place in front of a monochrome imager. Black-and-white pictures can be quite beautiful and reveal subtle contrast and nuance in ways that color cannot. They are more sensitive and produce black-and-white images that are easier to learn to calibrate and adjust. Previously, I've pleaded with beginners to start with monochrome cameras. Which is better for astrophotography, a color or a mono camera? Both of course! ![]()
