I respectfully disagree that it takes 4 times the time. With luminance, you're capturing (for a broadband target e.g. galaxy) photons at 3 x the rate of an OSC camera, as each pixel in the OSC is rejecting 2/3 of the photons hitting it (even before QE). So with some basic colour data to colourise it, I'd argue that you can take the same or better quality image in perhaps even less total time with a mono camera than an OSC one. Leastways for a deep enough image that that extra L depth makes up for the RGB capture time.
Of course, if clouds come in before you get a complete set of data then you're stuffed, whereas with an OSC you can process what you've got :-)
