With increasing levels of light pollution degrading our skies every year, technology has thankfully come to the rescue in the form of imaging filters. These popular accessories can have a profound impact on your image quality, notably when nebulae are your targets of choice. Simply put, light pollution filters work by selectively blocking certain harmful wavelengths (light pollution) while transmitting the precious light from your deep sky target. Other filters make it possible to produce true color images from monochrome cameras - so popular these days due to their efficiency and sensitivity. From a simple “dark frame” imaging filter, to a highly sophisticated 3 nm narrowband filter, we have the filters that you need to improve your astronomical images!
