Render to infinity?

Is there an easy way to render an object to infinity (putting something way off in the distance so that its dimensions cant really be made out) like a mountain.

I’ve got a room that has a view of a mountainous vista in the distance but even a few metres into the room as soon as you get closer to the edge perspective has an effect and makes it look closer than I want it to be.

Additionally, I’ve tried moving the object as far back out of the world sphere indicated in the orthagonal views but it doesn’t make much of a difference?
