Hi Mario,
Although I don't own a filter wheel (yet) or a new camera (yet), you are on point.  You can also have separate Hydrogen, Sulfur, and Oxygen filters as well in the wheel.  Many options/models to choose from...I've looked at 5 position/7 position models.  Some wheels are automated via various programs like APT so all you do is program it and let it go.  Others are manual.  I'm sure many more of the folks on the forum have the experience with these.

I've even seen bundled ZWO/Filter wheel combos with filters.

Awesome. Thank you both.

If the resulting images from a monochrome CCD are, well, is the colour added to the final image?
Practically, do you just use a filter wheel and take separate Blue, Green and Red lights which are then stacked together later?

I'm assuming this is correct as I've read references to this process.

Should we be gunning for the biggest number we can afford?
