I made it there last weekend. A scouting trip but with a bit of acting like a tourist as well.
Set up my 20x80s (Argo Navis-directed of course

) to have a first look at the skies. The photo is close to where I set up, but back about 20m from that 300m drop cliff down into the Ramon Crater. Spectacular place and amazing country.
I could see the dome of one of Tel Aviv University's observatories just over the hill behind me to the West.
A fair light dome from little (5,700 population) Mitspe Ramon to the East, but pretty good skies overhead and to the South and West. SQM meter down to 21.1 around 11pm.
Compared to northern Israel that is plagued with poor visibility mainly due to dust, visibility was very good here.
Looks like a promising location for a few visits a year. Just a longish (3 hour) drive on extremely busy and fast highways to contend with.
Best wishes from north of the equator
