hi,
just a quick question for shooting milky way timelapses. At constant aperture (wide open), is it better to shoot with long exposures (for example 30sec with high ISO) or stack multiple smaller exposures (for example 10sec by using multiple echos in additive mode in after effects ans maybe lower ISO also)?
The first solution will get more light and maybe more small stars (a supposition) but the 2nd will help a lot decreasing noise and you can easily choose how many echoes you want before having trails.
Maybe it's just a matter of gear. With a Canon 6D and a f/2.8 or f/1.4 wide lens, maybe noise is not a problem at high ISO but with my Canon 550D and a Samyang 8mm f/3.5, if I go beyond 800 ISO, it start to get noisy.
Here is a exemple with echo stacking (10sec exposure, interval 11sec, f/3.5, ISO 1600, stacking : echo with 4 pictures in additive blend mode with 0.8 decay, final speed x2).

It's not really a good milky way timelapse (my first test ever at shooting stars and not the better gear to do it), but it's just to add some video to the post
