The Milky Way with some friends in Colorado [OC] [2595x3000]

The Milky Way with some friends in Colorado [OC] [2595x3000]

This was taken one night while doing some geology work in Colorado. Some friends had never seen the Milky Way before, so I knew I had to let them in on one of life's greatest pleasures. Looking at the Milky Way for the first time was one of the most surreal experiences I've ever had.

Equipment and acquisition:

Canon T3

Tamron 17-50 f/2.8 @ f3.5

iOptron SkyTracker Pro with Manfrotto tripod

Acquisition

Taken in a Bortle 3 location

15x60" shots

Processing

Color correction

noise reduction

Masked Stretch

reduce stars

I was really surprised with how much Ha data I captured with just a T3 and a pretty cheap lens. The lens and camera body together only cost me around $300. Low light pollution really is a blessing along with over 9000' elevation. If you feel like looking at some of my other images or following me on social media, here is a shameless plug to my instagram

One nice thing about Colorado is that it's easy to put some mountains between you and major sources of light pollution.

Look for a place that is blue or better I think would be best in terms of distance away and view benefits

Just curious where and / or how far from, say, Denver, I could go to see something like this?

Yes, this is definitely a composite - I'm not going to hide that - All shot on a Sony a7ii with Sony 55mm f/1.8 lens. Foreground is 3 horizontal images each shot at 55mm, 1/3s, f/4.0, ISO800 - sky is 6 mosaic images shot at 55mm, 40s, f/4.0, ISO1600 (tracked using an iOptron Skyguider Pro)

Merged in PS6 and processed in Capture One 10. Happy to answer any questions folk have.

Multiple photos of the same thing, yielding dimmer pictures, merged together for a unified, brighter and clearer picture.

Where abouts is this mate? We're in queenstown at the mo but heading up north soonish. I wanna do here!

What is a composite?

Did you point the camera and click the button?, or did you do some photoshop on it?

Frost on Mars [478x512]

Frost on Mars [478x512]

This high-resolution color photo of the surface of Mars was taken by Viking Lander 2 at its Utopia Planitia landing site on May 18, 1979, and relayed to Earth by Orbiter 1 on June 7. It shows a thin coating of water ice on the rocks and soil. The time the frost appeared corresponds almost exactly with the buildup of frost one Martian year (23 Earth months) ago. Then it remained on the surface for about 100 days. Scientists believe dust particles in the atmosphere pick up bits of solid water. That combination is not heavy enough to settle to the ground. But carbon dioxide, which makes up 95 percent of the Martian atmosphere, freezes and adheres to the particles and they become heavy enough to sink. Warmed by the Sun, the surface evaporates the carbon dioxide and returns it to the atmosphere, leaving behind the water and dust. The ice seen in this picture, like that which formed one Martian year ago, is extremely thin, perhaps no more than one-thousandth of an inch thick.

Thought you were just really smart for a second. Then I realized you just copy/pasted the text from the description. Regardless, thank you for the information, it's greatly appreciated :)

What a neat picture.

I always get a little sad when I see pictures of Mars like this, because it reminds me of a planet that was likely much, much more robust and geologically active with stuff like active volcanoes, running water, a much thicker atmosphere, and weather. It would have been really cool to see what Mars was like back when it's core was much more active and still generating a magnetic field.

True Colour Image of Venus [3500x3500]

True Colour Image of Venus [3500x3500]

Fantastic! I was just having a discussion yesterday about what it "actually" looks like. Though that was centered around what it would look like in person, which was determined to be "blindingly white" haha

http://planetary.s3.amazonaws.com/assets/images/2-venus/20120913_3447783055_7201387b94_o.png

actually to the human eye it just looks like a white ball- theres even less visible cloud than in OP pic. and underneath hell awaits to melt and crush and boil you.

actually more freaky in a way.

This is not a "true-color" image as it was made from orange and UV filters:



Image color
Filter



red
orange


green
0.8*orange + 0.2*UV


blue
0.5*orange + 0.5*UV

The reason we see any features at all in this image is because of the UV filter, which shows areas where the unknown UV absorber is upwelled.  In visible light, Venus is essentially featureless and white, as seen in this MESSENGER image, which is much closer to how it would appear to the human eye.  The MESSENGER image was taken through visible-light filters, which although not exactly corresponding to red, green, and blue, are a lot better than using the orange and UV filters.

But OP, you are right in saying that it's closer to what Venus actually looks like than the colorized Magellan radar maps.

Wow, I didn't realise it would be that bright. But yeah, I can't believe more accurate pictures aren't being used to symbolise venus. I actually thought for ages that Venus looked like this from space. I had no idea how wrong I was.

That silver Meteor piece almost looks like a quarter. Fascinating.

Didn't realize aliens used currency too

It's not a meteor

Meteor Explodes Over Michigan - 1/16/2018

Imagine if something like this coincidentally coincided with the false ballistic missile alert.

NASA: Meteorites 'likely' on ground in southeast Michigan

That article also has an awesome video posted by Nasa Meteor Watch.

The meteor caused a 2.0 magnitude earthquake.

Take an upvote for "coincidentally coincided"

It shook our building a bit.

The debris isn’t far from where we live. Time to go hunting for meteorites.

Quite the combo there. Kudos to the photographer.

Not the source of this photo, but another great set of shots like this, plus all the details of how it was done:

And everyone laughed when they said they'd land on the sun at night. Sure proved us wrong.

Thanks for linking this. I love Destin’s excitement

That doesn't look flat what the hell lol

I always forget how massive Africa is. This really puts it into perspective.

I mean sure it was a huge hit, but I believe Toto is overrated.

I know it's a joke/running gag, but can we please stop feeding these flatheaded idiots?

Is it strange that all I think of when I see things like this is "this is something I'll never see with my naked eyes", which makes me very sad.

Not with that attitude.

not with that altitude

For those curious, THIS is Cassini's actual last image (thats not a composite)
