Welcome.... I have never done that so I can say nothing.... but like almost everything I do, after about fifty trials, and one of these is the way I like it, I have one success and forty nine I know I do not need to try again. I kinda like the star trails. Look forward to seeing more. and Welcome to NRF, PAD
And to the "Outer Banks of NC" welcome to some beautiful space....grab a sunrise. i am a couple hundred miles to your west in Greensboro.
And as far as stepping out the front door of the RV....love it! Will be doing this soon myself.
Great stuff on PAD
