Markarian’s Chain of Galaxies Revealed
Thanks again to Terry Hancock for sharing his capture of “Markarian’s Chain of Galaxies” in the constellation Virgo. This image was taken over two nights with a total acquisition time of 14 hours using Chroma Technology‘s LRGB filters at Grand Mesa Observatory in Purdy Mesa, CO, USA.
Chroma manufactures the highest quality 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 and 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. Chroma provides custom coating services for more demanding imaging applications requiring larger apertures such as f/3 or f/2. They also can provide larger sizes and unique passbands upon request.
