My first attempt at imaging the Bode's Galaxy (M81) and the Cigar Galaxy (M82) using an HaRGB palette with my monochrome ASI1600MM camera.
I'm pleased with how the hydrogen regions stand out more prominently with the added Ha channel. Broadband imaging under Bortle 7 skies is difficult due to the increased light pollution and resulting noise.
Integration Time: 3×20×180s (RGB), 10×360s (Ha)
Gain: 1 for RGB and 200 for Ha
Telescope: Skywatcher 200/800 Newton
Mount: EQ6Rpro
