Hello i am wondering you know how adaptive optics you need to Split half the light with a beamsplitter so you will see half as much light would you also see half as much contrast as well or is it only half as much light with a beamsplitter?

Contrast can be defined in a confusing number of ways, but for simplicity here, no, only the light is cut in half, the contrast remains the same. 

 

Binoviewers work this way (usually). 

 

 

Clear skies!
