Take a look at the graphs on this page, and read

But the details indicate that only the green channel of the D50 is
much superior to the Canon. The D50 appears to be more noisy for gray
images than even the D70.
Gray (luminance) is composed 50% of green and 25%/25% of red and blue.
The graph shows a superiority in noise of the D50 hence your statement
is incorrect.
Since most astro images are going to be
black backgrounds, I'd be concerned about the gray image noise.
See above.
The
graphs also show the D50 to be very noisy in the red where most nebula
reside.
Not in the red. In the H-alfa.
