Hi Mick
The advantages of the mono can be broken down into:
1. Greater resolution (60% better). The mono allows the full 640x480 resolution in each colour channel. The colour bayer matrix only captures 33% resolution in each channel.
2. Ability to change settings each colour channel: Ensures proper weighting of the histogram in each channel
3. Ability to refocus each colour channel: Ensures a sharper image in each channel.
Is your question comparing the DMK21 to the DBK31, or in general, the DMK (mono) to the DBK/DFK (colour) versions?
What's your intention with the camera? Lunar or planetary imaging?
