That's a great suggestion--thanks! I'll give it a try.


Meanwhile, my first attempts at LRGB imaging are here:

As an available cheap solution, you might want to also want to explore using the  "DigitalColor Meter" application (it's in your Applications/Utilities Folder ). It has the ability to measure the RGB color pixel values of a single or block of pixels under the cursor in real time (for real time, you need to set this in it's Preferences)..I've used it in the past for  color balancing planets and also determining  how much actual image brightness I'm getting too. I like to keep my target brightness around 50 to 65% of the maximum pixel range (i.e. 125 to 165 for 8 bit cameras) to so that my white areas don't get over saturated or set too low. I find that when I'm looking at the LapTop screen in the dark I grossly underestimate the brightness of the target.
