The galaxy center of M82 is active with high rate of star formation caused by the gravitational effect from nearby spiral galaxy, M81.
This is a composite image taken from two different telescopes and two different cameras. The color is from a Canon T1i that was collected in 2011. The QSI 683wsg-8 was used to collect Luminance and Hydrogen-alpha data.

RGB data: 360 second exposures stacked in DeepSkyStacker and processed in Photoshop for a total integration time of 6 hours and 26 minutes.

Luminance data: 360 second exposures totaling 2.2 hours of integration using QSI 683wsg-8.
Hydrogen-alpha data: 20 minute exposures totaling 2 hours and 40 minutes of integration using the QSI CCD camera
