Reply to comment by ajamesmccarthy in I spent 20 hours shooting the Horsehead nebula to create my most intricately detailed photo of this region. This area is surprisingly large, and if it were brighter it would appear much larger than the full moon. Make sure you zoom in! [OC] by ajamesmccarthy

Thanks for posting this. I do some very casual stargazing myself, and love to see what's possible for a dedicated enthusiast.

I pointed my little 60-power scope at Jupiter during closest approach recently and watched the four moons Galileo saw, as they moved about from night to night. Very exciting! That's about as serious as I get....

The fact that it would take 2800 lifetimes traveling at the speed of light (assuming 100 years per life) to travel that trail blows my fucking mind….

When we think of space, we generally think of just stars. But our sky is actually quite crowded, very seldom is that empty space between stars actually "empty". When you look at the orion constellation, for example, you would never know that this is hidden in that area. It's surprisingly large, too. Look at it compared to the full moon!

Captured using a 12" telescope on an equatorial mount, this was done over several nights. The mount is designed to compensate for Earth's rotation, and is the sum of hundreds of 2-5 minute exposures captured over the course of 2 months.

The colors are actually real (although a bit saturated for taste). If you were to float out in space in front of this with your phone and take a long exposure, these colors would show up just fine. However, if you were to just look at this area with your naked eyeballs you'd see mostly black space with a gray haze where the "flame" is. That's not because this area isn't incredibly vibrant, but because your eyes can't resolve color when things are this faint. It's like trying to see the color in flowers in moonlight, you can't.

Dude looking up into the night sky and, instead of seeing an arm, seeing your entire ass galaxy?? so damn cool

Sorry, i was rushed and didnt make myself clear.

I meant, how is it moving? Separately? Away? Synced??

Its unimaginable. Everything outside the tadpole is another galaxy. And this is just a tiny spec of the sky around us. Our brains can’t comprehend it.
