Suffice to say, JPL/NASA/ESO/JAXA don’t fly colour cameras.

If you are time poor/just want some fun/technically challenged, then the new colour cameras can give great …in fact occasionally…award winning results.

But for sheer depth and breadth of intrinsic data…. mono wins every time.
Hi Peter,
You omit in your list the two things that slow me down moving to Mono which are $$$$ and clear sky time. Mono is substantially more expensive.

I also ponder about the time taken up in focussing between filters and repeating this when the temperature changes. DSO targets transverse quickly in the sky and time is of the essence. Also potentially if Mono imaging starts at altitude 50Deg on Red filter and the next filter is at 65Deg (for example illustration) then filter at higher ALT will be a better image. With OSC all the colours are balanced at each ALT imaging range.

Chris.
