To improve your view of the night sky, you can add deep sky filters to your telescope. Deep sky filters will reduce the impact of lights from buildings and the city infrastructure. City lights aren't the only source of illumination that can hamper your stargazing. When the temperature falls during evening hours, the release of energy from daylight hours gives off small amounts of light. By using deep sky filters, faint objects such as star clusters, galaxies, and nebulae, can become apparent. The deep sky filter works by cutting out a specific spectrum of light, such as those emitted by streetlights.
