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.

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:

A cropped and de-scaled version of the original [2h 20m total integration time, 400/4 (to get the 'sunstars') ISO 800].

"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.

I could try and better that but I would rather just look at it, lovely.

First shot of the moon using the Skywatcher 120mm x 1000mm fl Black Diamond refractor telescope and the ZWO ASI1600MM camera

All my previous moon imaging was with a DSLR camera and telephoto lens

Recent lunar pic:

Along the centerline is Rima Hyginus (with crater Hyginus), above the rima is Mare Vaporum (the lava flows have only a few hundred meters elevation variation), below the rima are the craters Hyginus A, Triesnecker, and at the base of the 600m high eastern ridge of Murchison, Chladni (which is relevant since we just covered sound in Physics I)

HI recently I made some scope pictures of Arcturus and Spica.(its quite fuzzy due to long exp. time) but I think that colour difference is remarkable (Arcturus surf temp. cca 4300 K, Spica cca 24000 K).

Tour of the Moon in 4K (NASA Goddard)
Take a virtual tour of the Moon in all-new 4K resolution, thanks to data provided by NASA's Lunar Reconnaissance Orbiter spacecraft . As the visualization moves around the near side, far side, north and south poles, we highlight interesting features, sites, and information gathered on the lunar terrain.

very cool

The clouds parted for 2 days, and while the moon is annoyingly bright, I was able to get a nice start on M101. The first image includes some surrounding galaxies, while the second is a close-up. Images acquired with a 400/2.8 lens, 15 second exposures (yay, declination!), ISO 500.

I can still do a good bit of denoising and improve the flat field correction, but what I really need is less moonlight.

Another good night of viewing- no moon this time. Up to about 2 hours total integration time.

Hi I attach moon colour enhanced image (registax+photoshop). Are you experienced with this process ? O would like to know if is true that you can visualise true colour of object (for example rock of moon and so on) which can not see by naked eye...

Have nice astro experiences

awesome effort

just remember tho, the moon isn't really that colourful ... it's basically all grey

up this thread a few posts back...
Post #302 ... my moon pic and post #304, Andy's pic. show the natural colour of the moon

So in summary ... great detail in your pic., just go easy on the colouring Dave

 

[bruha]

Hi thank for your post. Ya I noticed as well that moon is basically grey (since some green and blue rare rock are present as I read). It is as I read quite lot instruction on web how to enhance image moon colour and just wandering if it is only " game" or has it some relevant (real) matter.
You have absolutely beatiful and detailed images. -congratulation

thankyou

you didn't comment on what telescope, camera etc you used to take that image ?

There is real science behind colorimetric imaging of the moon, primarily in connection with minerology:

Enhancing the color (increasing the saturation) is a fairly standard approach:

The region around Aristarchus is especially colorful:
