Cassini's picture of Saturn with the Sun behind Saturn

Very nice!

Meanwhile, no satellite, no flyby, no animation, no photos, no video, no NASA tech crew - nothing but birding binoculars and naked eye; but as a total beginner I was pleased to get my own first-time view of Saturn last night, a very bright dot just below and to the left of the equally bright waxing crescent moon. The dot really did seem gold in color; I thought this might be my imagination until I looked it up.

Great ISS flyover this evening:

Let's try that again...

Nice what setup did you use

Nothing fancy- my telephoto lens (800/5.6) and a tripod. TIF images acquired @ 1/1600s, ISO 800. No mirror lock-up, etc.

Some notes on perspective,
https://www.nasa.gov/feature/goddard/2017/osiris-rex-snaps-pictures-of-earth-and-the-moon
"This black-and-white image of the Earth-Moon system was captured on Sept. 25, 2017 by NavCam 1, one of three cameras that comprise TAGCAMS (the Touch-and-Go Camera System) on NASA’s OSIRIS-REx spacecraft . At the time this image was taken, the spacecraft was retreating from Earth after performing an Earth Gravity Assist maneuver on Sept. 22. Earth and the Moon are shown 249,000 miles (401,200 kilometers) apart, and the spacecraft is 804,000 miles (1,297,000 kilometers) from Earth and 735,000 miles (1,185,000 kilometers) from the Moon."

This pretty much rules also.

This is a worthwhile use of hard drive space, hours of fun. (you won't be disappointed). I recommend beginning with a tour of "Universal Beauty" in honor of this thread)

The home site https://aas.org/ is also highly recommended if you don't already use it.

Captured in one of NASA's observatory in 2016. It is 20,000 light years away.
This is called the Art of Science.
Not literally. But this is very beautiful. Majestic.

can you please give a link to the origin of that image ( a good thing to always do)
I would like to identify it

Deep Star Maps
Visualizations by Ernie Wright Released on January 17, 2012
(from NASA/Goddard Space Flight Center Scientific Visualization Studio)

"This set of star maps was created by plotting the position, brightness, and color of just over 100 million stars from the Bright Star, Tycho-2, and UCAC3 star catalogs. The constellation boundaries are those established by the International Astronomical Union in 1930. The constellation figures also come from the IAU, although they're not official."

What a good diagram! Where did you find it?

My mistake. It should have said APOD (Astronomy Picture of the Day). Just click the link in the original post.

 

[ISamson]

Ah. Nice.
Thanks.

Thank you for sharing that. I was trying to come up with a list of my own for a presentation, but this is super clear.

I'm goofing off too much. My first thought at seeing that was Settlers of Catan.

The Pleiades are coming into view (for me) now. it also warmed up a bit, so being outside wasn't totally unpleasant:

"American Scientist" recently had an impressive photo essay (via Cassini) of Saturn's rings:

After a long winter's nap, the weather is becoming more conducive for astrophotography here in cleve-o. Last night I got this image of the Flame and Horsehead nebulae in Orion:

Total acquisition time: 2 hours with my 400/2.8 wide-open. Single frame info: 10 s, ISO 800. Not bad for urban viewing conditions!

 

[Andy Resnick]

Rosette nebula:

2h total acquisition time @ 400/2.8, ISO 800... this is definitely one of the trickier ones.
