I'm usually at 14mm, f/2.8, 30 seconds, and ISO 2500 to 3200 for Milky Way around here. My D700 won't cleanly go higher than that, and even 3200 is not ideal, so 30 seconds is a must. With the Ramper Pro I set my interval ramping from 15 seconds (about 4 photos per minute) to 3 seconds (about 2 photos per minute at 30 second shutter) over 96-120 frames when I hit about 5 or 10 second shutter speeds so it's very gradual when played back at 24fps and barely noticeable that you almost doubled speed in 4-5 seconds of real time playback. Of course, it depends on how much cloud cover and how fast they are moving. Ideally you want to have ramped the interval soon enough before the Milky Way really shows so the Milky Way appears to keep a constant speed. I'm still experimenting with those numbers. 120 frames can be too long if the light changes fast because you bump into your shutter speed length. The Ramper Pro seems to handle that OK, but you aren't getting a smooth interval ramp either at that point because it's adding it to the length of your shutter. It's hard to find much advice about interval ramping...
