Hi! I tried astrophotography for the first time this weekend, and have a few questions. I've read many times that an F4 lens isn't fast enough for astrophotography, but it was my only option this weekend. I think the outcome was far better than I expected, although my "standard" for results probably isn't that high. Anyway - I tried 30 seconds F4 on approximately 16mm, on a tripod of course. I can see glimpses of the milky way, but not as clearly as the "typical" astro-photo you'd see from an experienced photographer. Question 1: Which camera settings (shutter speed, aperture, iso) is preferable in order to capture the milky way? Question 2: Is it not enough with only one photo or are you supposed to stack multiple photos? Question 3: What is the benefit of stacking photos - will the milky away appear more clearly, or is it to reduce noice? Feel free to advice me (and other beginners) on how to make the milky way appear more clearly. I'm sure the camera settings should have been different . I'll throw in a couple of sample images from this weekend. Both are edited in LR.
