Now, Aram... when you say a separate shot, were the two shot from a tripod,
without moving it between shots? Just the exposures blended, as it were.

Or was the sky a completely different shot, blended into the black sky of the
fire & people shot?

Curious minds want to know!

Using the 16-35 Nikon. For this shot it was 20mm, f-4.0, 30 sec. The fire
is a separate shot at 8 sec, then blended.

Hi Aram!

Nice shots of the VLA. But the winner is the star shot with your Swiss
campers. Beautifully done!

Without knowing the focal length, it is impossible to guess the shutter
speed based on the length of the start-trails (very short but visible).

So, I'll ask. What focal length were you using?

Tnx.

David.

Just outside Socorro, New Mexico, is the Very Large Array. We were lucky
that they were in the D configuration. That means the 27 radiotelescopes
were bunched close together around the visitors center. This is when they
are looking for lower resolution overall structure images. The A
configuration is when they are spread out with each arm being 13 miles.
You would get to see very few of them close enough to the visitors center to
photograph.

And just down the road is a nice campground, where I found a couple from
Switzerland enjoying the stars by a campfire.
