Compass and Scale Image for NGC 2841
About 46 million light-years (14 million parsecs)
The image is 2.6 arcminutes (34,000 light-years or 10,500 parsecs) wide.
The image was created from Hubble data from proposal 11360: R. O'Connell (University of Virginia), B. Balick (University of Washington), H. Bond (STScI), D. Calzetti (University of Massachusetts), M.

F336W (U), F547M (y), F657N (H-alpha + [N II]), and F814W (I)
This image is a composite of separate exposures acquired by the WFC3 instrument on HST. Several filters were used to sample broad and narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
Blue: F336W (U)
Green: F547M (y)
Red/orange: F657N (H-alpha + [N II])
Red: F814W (I)
