Question

Using 3.2.2 Premium with a 450D. This is probably more of a general photography question than a BYE question, as I know little about photography and only got into it for astrophotography purposes so the learning curve is extra steep for me. But the question I have is about the actual difference between shutter speed and aperture. I've read up on it and I understand the difference (I think) for regular cameras, but I don't really understand it for DSLRs since there is no real aperture. I know I can set both of these in BYE. Obviously changing the shutter speed will literally change the amount of time the camera sensor is exposed, which changes the exposure of the resulting picture. I'm sure it's wrong to use the term "brightness" but that brightness increases with longer exposures, of course. But then I get confused about aperture. Is the camera simply using a formula to increase the "brightness" of the image captured based on the aperture setting?
My question was originally going to be, what aperture setting should I be using if I have my camera connected to my telescope? My guess it that I set it to whatever the focal ratio of that telescope is - in my case, it is f/10. So I should set BYE aperture value to f/10 and then use shutter speed to control exposure correct? Is there any reason I would ever want to use the aperture value to control exposure/"brightness" when using a telescope as my lens?
Thanks in advance and sorry for the newbie question.

Sorry, but you are incorrect to say that "for DSLRs there is no real aperture." There is, and you can set it from BYE...under 2 conditions. 1) the camera must be in Manual mode. If it is in full

With my T5i I cannot cause the aperture dropdown to display in the Capture Plan Center or the aperture setting in the Camera Information Center unless I have an adjustable lens mounted on the camera.

This is odd. Try deleting the cache in BYE. See Advance Settings.
