I do not know if my camera has a function similar to that.. I will investigate that further when my sister comes over this weekend, she got a lot more expertise when it comes to cameras than I do

I tried that out in the picture I linked to in my last post, but I never took a photo explicitly for the moons. I found a picture of the moons later when I was going through all the pictures later that night, when I took it I only saw the over-exposed Jupiter
I'm gonna take another photo tonight hopefully where I'll focus on getting the moons well exposed.
Also, I realized that I cannot change the shutter settings (the "F" parameter) without having a actual camera lens.. Is it like this on all dslr-cameras? Or is there camera lenses out there that can be attached directly to a adapter and then onto the telescope?
The equipment I'm using to fit the camera on the telescope are these:
