I been planning on taking the Palm Canyon road in. There are some volcanic cones pretty near the road that I think are hike-able to provide some elevation. Probably about 1/2 mile of hiking round trip. This year the weather, and just life has gotten in the way of getting out there.

I like your humor - +30C isn't extreme at all, especially here in the southwest sonoran desert - even at night, especially during the summer. That said, I've starting to use LENR on the foreground landscape shots, but my astro/star shots have been pretty clean.

I'm also considering taking a single dark frame at the end of the shoot and then using that to process all the previous foreground shots. I'm usually shooting 50 to 60 second sky and foreground exposures, although for some darker locations (Kofa*, would probably need longer foreground exposures).
*Kofa - Kofa (King of Arizona mine) National Wildlife Refuge, has supposedly been measured to be the second darkest location in the continental US.
