View of the Andromeda Galaxy
Here is another image shared by Tony Hallas: the center of the Andromeda Galaxy, located about 2.5 million light-years away from Earth.
This photo was taken using Chroma astronomical filters in California.
Chroma Technology 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.
