Thanks Brad. Happy Friday! :)
I’m a newbie at photography too so I get it. For the still panorama stuff, I just used the panorama setting on the Rx100. For the actual moving panning shots, I used a mechanical panner: http://www.flow-mow.com/  It’s 2 oz. I mounted this to a baby tripod called an ultrapod mini: https://www.amazon.com/PEDCO-P-UP-MINI-Pedco-UltraPod-Mini/dp/B003ITCFT4  However, I regret not slowing down the footage to reduce the vertigo inducing effects. One of my many rookie mistakes.
As for the star shots, I downloaded a $10 app called “Timelapse” from the sony playmemories store and installed it on the camera. It worked great on the rx100m4, but I’m not positive it runs on the mark 1 that you have.  Settings were ISO1600, F1.8, and 30 second exposures if my memory serves correctly.
The Rx100 sensor is pretty small, so there was a fair bit of noise I had to clean up in post using an app called neatvideo http://www.neatvideo.com
Many of the night shots are actually multiple videos/stills composited together and then individually and collectively animated. Ie. the Whitney nightlapse sequence is a star timelapse I took on Island pass that I animated to crossfade to a sunrise still shot. I then layered a Whitney still over that with the sky cut out to reveal the first layers. The headlamp simulator I built in Motion 5, then put on an animation path tracing the trail, and then I collectively automated a pan on the whole thing while warping the edges slightly to create a moving camera like feel.
Hope that helps. I’m happy to answer any other questions you might have. Btw, everything mentioned above, minus the animation stuff I learned on the BPL forums from fellow members. :)
