Jen, I have used a similar camera that I borrowed from a friend of mine. It is called the Stellacam. He lent me a small Security TV screen that he also bought to use with it in the field. For this setup you dont need a laptop. And it provides nice visual observation without the need to look in the Eyepiece. Also these cameras provide a inbuilt frame integration so what you see on the screen is a stacked image showing more detail than what can be seen by the Eye. From my backyard in burbs of Sydney i could not visually see centauras A but witht he stellacam/TV combo i could easily make it out.
So a laptop is not required. I used this setup with my Lx90 and was able to see things i would not otherwise be able to see. You can also connect it to a regular TV inside the house and watch there.
There is a lot more information on this forum section on CN that caters specifically for this type of observing.
