With my previous cameras, I have always used camera settings and/or an intervalometer to shoot astrophotography. My question(s) are:- what are the differences between the Time Lapse App and the Star Trails App. The way I am reading the description they do basically the same thing. Am I wrong. I shoot RAW images when shooting Star Trails for more control over the PP . The description says that the images are done in camera and produce a movie. I want the ability to import the 100+ images into my computer and then work on them (I use StarStax) (manipulating WB; cloning out intrusive airplanes, etc). Any answers/suggestions would be greatly appreciated.
