M82

From the same data acquired for M81, here is M82. Note the Hydrogen details (red colored, taken with a 2nm Ha filter)) especially under the galaxy and the dust lanes.

I think I've reached the resolution limit permitted by my telescope (AstroPhysics 180) and the seeing of my town (Fagagna in Italy); for more I would need a 0,5m from NewMexico desert :-)
