Explanation: A brilliant yellowish celestial beacon, Mars still dazzles in the night. Peering between clouds the wandering planet was briefly joined by the flash of a meteor in this moonless dark sky on November 18. The single exposure was taken as the Earth swept up dust from periodic comet Tempel-Tuttle during the annual Leonid Meteor Shower. The view of a rugged western horizon looks along the Yulong mountain range in Yunnan province, southwestern China. Yulong (Jade Dragon) Snow Mountain lies below the clouds and beyond the end of the meteor streak.

Please add me to your list.

New desktop background.
Dave, you have been added to the APOD list.
Please add me to the Ping List. I’m here all the time, anyway, LOL! :)
Thanks
The mountain’s name and picture are beautiful.
Any dragons or Jade on the mountain?
Is this photo a group layered on top of eachother or a long exposure?
I am asking because I am trying to figure out how the photographer got enough exposure time without the movement of clouds being blurred.
I don’t know the photo technique that was used. You make a good point.
Did a little digging around. This guy is on Facebook ( I dont do Facebook so not posting a link) but also shows up in alot of other places. Write him, he might tell you. He is also on Instagram.

Thank you. I was making dinner and didn’t look into the original link as of yet.
I actually have that website running in one of my web browsers right now.
I am trying to get into astrophotography beyond the occasional eclipse.
This isn’t the 1800s. Digital cameras can have ISO speeds in the many 100s of thousands.
I am quite familiar with digital cameras since I own a professional model Nikon.
Which is why I asked about the photograph is such technical specificity.
Ya see, to gather the light needed to get a nice bright image of faint stars you typically need a long exposure time or you take multiple shots at a shorter exposure (8-20) and stack them in post editing.
If you use an equatorial mount, pointed at Polaris and set to the hemisphere you are in (north or south) then the mount rotates at at a speed that keeps the camera positioned on the object (star, moon, sun) so you can have a long (30 seconds or kore) exposure time without getting star trails.
Knowing those technical facts and owning both an equatorial mount and having photographed the moon, stars, and a total solar eclipse....tha is why I asked about the technique sued in this particular photograph.
Because even with the slightest of breezes, a long exposure time which would get the clarity if the stars and constellations, the clouds would be blurred.
Anf if you had a 30 second or less exposure time photograph the clarity of the stars and constellations would not be this good unless you stacked multiple photos in post editing....and with any movement of the clouds.. .you are back to a blurred cloud.
Which is why I asked the question......because I do not know of a technique that makes it easy to get/capture/create the image shown
Sooo....I explained all of that to you even though you really don’t care at all other than to make some snarky bullshit comment.
Good day Sir.
What a great website with amazing photographs.
Thank you for sharing it.
The spirit of war on earth is released in the heavens???
