The Seagull Nebula Up Close
Here is another fantastic image from Terry Hancock! The Seagull Nebula (IC2177 and NGC 2327) is located in the constellations of Monoceros and Canis Major, lying at a distance of 3,600 light-years from Earth. This image was taken at Grand Mesa Observatory in Colorado over the course of 4 days with a total acquisition time of 14.6 hours, using Chroma narrowband filters.
Chroma Technology manufactures the highest quality filters and filter sets, including astronomy filters with durable, sputtered hard coatings using single substrates of the best glass, eliminating the need for laminations. All primary filter coatings are applied on the front surface and anti-reflection coatings on the rear surface to prevent ghosting and to maximize transmission.
Highly precise and accurate, the passbands of these filters remain spectrally stable. They do not drift in response to extreme temperature fluctuations or changes in humidity. All filters may be used with apertures of f/4 or smaller. We provide custom coating services for more demanding imaging applications requiring larger apertures such as f/3 or f/2. We also can provide larger sizes and unique passbands upon request.
