Hello John,
Welcome onboard & I'm sure that there'll be quite a few who are jealous of your dark sky site.
As to which Planisphere is best.......Can't say, coz I only use the large Chandler
variety & it is easy to read & cheap as chips.
Please don't forget that you'll need a red LED torch of some kind to save that
precious night vision.
I don't know if anyone is located in your area, but someone will.
&, don't put down the old 114.
A whole lot of us started with such an "instrument."
I know....I did.
Stay safe.
