Rosette Nebula image details

RegiStar Details
Full image

This composite image of the Rosette Nebula was composed by combining 3 black-and-white images. All photos were taken using a 5-inch refractor by Rajiv Gupta on gas hypersensitized Kodak Technical Pan film.

The 3 component exposures were taken using light yellow, dark yellow, and red filters. They were registered using RegiStar, and then combined into a single color image using Adobe Photoshop.

 

Two of the original black-and-white images, the light yellow (left) and red exposures, are below. The exposure times varied from 50 minutes for the light yellow exposure to 100 minutes for the red exposure.
