Reply to comment by --Ty-- in This is what 7 minutes of exposure time looks like on a dark, moonless night at Zabriskie Point, Death Valley (USA)! by peeweekid

In landscape astrophotography it's very common practice to shoot the sky and ground separately. For the sky exposure you use a star tracker that locks onto the sky as it rotates to prevent the stars from trailing (which of course causes the foreground to be blurry). Then you shoot the foreground without the tracker and line them up the way they would have if it was a single exposure.

How did you get that cloud in bottom right of the sky to look stationary?

Great question, since the cloud got really weird from the stacked sky exposures I took it from a single frame and put it back where it should have been before stacking.

I get that, I just think that it's important to state whether a photo is an actual photo, or a composite. Once you get into the realm of composites, virtually anything is possible, which means the work should be perceived and judged differently.
