Description

M81 & M82. Add some new data to some unused subs from last spring. The data from last spring has the supernova in M82 so it is showing up in the integration. High clouds limited the color integration and created some gradients so I kept the stretch pretty minimal. Red channel= 25% Ha/ 75% Red.
