Capturing the Rosette Nebula
This stunning image of the Rosette Nebula was captured over 3 nights in March at the Grand Mesa Observatory in Colorado by Terry Hancock. The acquisition time was only 4.75 hours.

The following narrow band optical filters from Chroma Technology were used to capture this image: Ha 5nm, OIII 5nm and SII 5nm. 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. 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.
