XDR
Extended Dynamic Range is used to
increase the ability to see objects in
dimmer area of the screen.
When XDR is set to LOW then the
GAMMA setting automatically sets to 0.45
(at least is says so, But I don’t see it
changing on the Signature).
For Astronomy use: Experiment
GAMMA
Adjusts the brightness of image. It is
actually the exponent on a power function
thus CRT’s and Laptops may require
different settings to enhance signal.
For dimmer objects set GAMMA to 1.00
for Medium set GAMMA to 0.7 and
brighter objects set GAMMA to 0.45.
When set to 1.00 then XDR, FOG,
ECLIPSE are automatically set to OFF (at
least that what is says in the manual. But I
don’t see it doing it. I do set them OFF in
my software.
For Astronomy use: YES
