APOD: A Sunset Night Sky over the Grand Canyon (2020 Feb 04)

Post by APOD Robot » Tue Feb 04, 2020 5:05 am

Image A Sunset Night Sky over the Grand Canyon

Explanation: Seeing mountain peaks glow red from inside the Grand Canyon was one of the most incredible sunset experiences of this amateur photographer's life. They appeared even more incredible later, when digitally combined with an exposure of the night sky -- taken by the same camera and from the same location -- an hour later. The two images were taken last August from the 220 Mile Canyon campsite on the Colorado River, Arizona, USA. The peaks glow red because they were lit by an usually red sunset. Later, high above, the band of the Milky Way Galaxy angled dramatically down, filled with stars, nebula, and dark clouds of dust. To the Milky Way's left is the planet Saturn, while to the right is the brighter Jupiter. Although Jupiter and Saturn are now hard to see, Venus will be visible and quite bright to the west in clear skies, just after sunset, for the next two months.

Did you mean to say “an unusually red sunset”, not “...usually...”?

Don't tell me what the poets are doing
Don't tell me that they're talking tough
Don't tell me that they're anti-social
Somehow not anti-social enough

Don't tell me what the poets are doing
Those Himalayas of the mind
Don't tell me what the poet's been doing
In the long passes over time

Don't tell me what the poets are doing
On the street and the epitome of vague
Don't tell me how the Universe is altered
When you find out how he gets paid, all right

It's a composite image. It says so in the caption.

I wonder if my DSLR is capable of taking such a "deep" photo of The Milky Way.
(I'm not referring to the entire composite APOD)

Any tips for me?

I have no problem in principle with composites- that's often the best way to capture a scene, or show something otherwise difficult to capture. But I agree that this doesn't look right, and I fail to see what it demonstrates astronomically. The colors, both land and sky, are oversaturated. The masking between land and sky isn't very good. In the real world you could never see a dramatic Milky Way and a sunset together.

This image is abstract art. As art, we can either like it or not. But IMO it's rather out of place as an APOD.

Most decent modern DSLR (or similar) cameras can take very nice Milky Way shots. Use as high an ISO setting as the camera supports without getting too noisy (which has gotten pretty high on many cameras- 3200 or more), shoot as long of exposures as you can without getting star trailing- with a moderately wide angle lens that's likely to be around 30 seconds, and then stack some frames (in fact, you may not need to do so- a single 30-second image may be all you need).

Andromeda?
Definitely not. You've circled the NE corner of the Teapot (Sagittarius), although the brightest object in there is actually Saturn. The streak is probably a meteor or a satellite trail. Andromeda is completely on the other side of the sky.

What, you didn't hear about the massive flood last summer that excavated out another few hundred miles of the Grand Canyon, pushing it clear back into Colorado? You're using the wrong news outlets!

Fixed. I could stare at that all day and not realize my mistake! Apologies.

This one I should have caught. And I have driven through Arizona (south to north) and passed not far from the Grand Canyon, too! (Couldn't visit. Long story. I will one day.) Both of these oversights have now been fixed on the main NASA APOD. - RJN

above Saturn there is a straight white line and a star(?) above that. Sitting at the top of the star is a red spot. Are these anomalies created by the digital photo process?

The star is 39-Omicron Sag (mag 3.8). Curiously missing is 41-Pi Sag (mag 2.9) which should be up and to the left of the dimmer star by about the same amount that Saturn is below and to the right. The streak is probably real- I'd guess a meteor or a satellite flare. Odd colored spots and halos around stars are imaging artifacts.

I know it's a composite, but this APOD amazed me when I saw it this morning. Even better as the full res image.

I'm not sure why you posted these lyrics, but it would have been polite to include the songwriters' names.
