Jellyfish Nebula Captured
Thank you to Terry Hancock for sharing some more of his astrophotography! This image is of the Supernova Remnant IC443, also known as the Jellyfish Nebula and Sharpless 248. It is located in the Gemini constellation, roughly 5,000 light years away from Earth. This was taken with Chroma filters, and took a total of 16.25 hours of exposure over 3 days from Grand Mesa Observatory in CO.
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.
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.
