Interesting that more and more color cameras are being pushed rather than mono lately, it seems. Not just for DSO (cooled color no amp glow with narrowband filters, but still a color sensor), but also for solar system. The 462MC for example is color and more sensitive to long wavelength, etc, since all the chatter is there regarding that new sensor compared to the classic 224 and the 290 sensors.
So here's the question....
Is there a relatively good metric or means to show the sensitivity difference between the modern color sensor versus the mono sensor?
I ask because while these color sensors are dropping with better long wavelength sensitivity, the idea there is that we're using narrowband filters to even get to the IR wavelengths. So it begs the question.... what's the sensitivity difference, real world, not theorhetical, of say a 290MM with a 742nm IR filter compared to something like the upcoming 462MC with the same 742nm IR filter? I realize the graphs show sensitivity difference, but it also makes me wonder.... using the same sensor, such as the 290MM and 290MC both with a 742nm IR filter, just to see what is the actual real world difference in sensitivity, IE, how much gain difference will be needed to get the same histogram?
Things I'm very curious about:
IMX183MM and IMX183MC with narrowband filters (610nm to 742nm), what's the real world difference in sensitivity (ie, how much gain needed to compensate to get the same histogram)?
290MM and 290MC with the same filter and question as above?
This is leading into questions on sensors like the 462MC and the 533MC which are more sensitive than color sensors before. So I'm curious how they compare to a mono sensor for narrowband filter captures.
