Wondering if anyone in here might be very familiar on the technical side of the RAMPER PRO 3 from Elysia Visuals.  I have read the manual but it is not very well written.

So here are my immediate questions if anyone can answer them.

1. I have a Nikon D810.  Is there any specific settings (other than f stop) that I need to set in order for the RP to work? I have the D810 set at F4 at 800th of a second on the camera.  Will the Rapper Pro (RP) automatically override the 800th shutter speed? If not, how should I set the camera in prep for shooting? I have it set to manual focus, and the camera set on manual with a fixed 4500K WB. 

2. I cannot see any preview during a sequence, either on my D810 or on the RP.  When I tap the histogram icon it tells me that the feature is not enabled during shooting.  How do I preview images, either on the RP or my camera body to ensure they are correctly exposed?

3. I want to use the "read jpg feature" so it will analyze histogram data.  However, during the daytime I want to shoot intervals shorter than 10 seconds (2-3 seconds) to capture motion more smoothly.  Since the histogram reading feature requires around 5-10 seconds to feed the RP with JPG data and read it, what happens when I have the histogram feature enabled but my intervals are shorter than the unit can read? This is important to know so I don't ruin a long shoot.

4. For a night to day shoot of the Milky Way, I am unclear how the system exposes the dim stars. I set my camera to 1.4f and a start ISO of 3200 with a 30 second interval.  Does the RP auto expose the ISO/shutter speed to the dark space enough to properly expose a bell curve histogram?

5. When I set my max ISO to something high, like 3200 or higher, will RP determine whether it even needs to go that high? Meaning could it never reach 2300?

6. If I have my interval set too low, say 10 seconds, but the unit needs 15 or 20 seconds to expose the image and another 10 seconds to fill my interval, will RP automatically adjust accordingly and prevent my 10 second interval from triggering another shoot cycle until the exposure is completed? Generally, I would set my interval to account for both the interval and the shutter speed, and I cannot find anything in the manual that instructs me on what to do.

These questions are ones in which I could not find answers on line or in the manual.  Appreciate as much detail as you can provide.  I have a very short learning curve as I am taking this out of the country to shoot arctic time lapses in a month.

I don't know the Ramper Pro, but have you looked at dslrdashboard as a solution?

Funny you say that. Another poster on the time lapse discussion forum suggested the same thing. I'll take a peek.
