Ha enhanced M81-M82
M81 and 82 showing H-alpha emission from starburst regions. Note the intense region in the centre of M82 on the right. Small regions of star formation show up in M81 as reddish knots in the spiral arms. This image is a combination of results from 3 sessions, one with an unmodified camera, one with a modified one to improve H-alpha transmission and one with a modified camera and an H-alpha filter.
