Tried the Morpheus 4.5mm and image was still bright.
So with the 4.5mm EP in the scope, your magnification would have been 178x, which is pretty high for the Moon. In my mind, the true test of control over CA occurs at high magnification. Do you recall seeing any CA at that magnification?
I know you said you saw zero CA, but at what magnification (and what EP) did you use? I'm assuming that was at a much lower mag.
All in all, I'm sure you're giving many of us that little (or not so little) tug of temptation with this scope!
