how do you get those colors of those deep space shots? Amazing work!

All those pics were taken in my front yard in northern VA about 30 miles from DC. The light pollution from the metro area is bad but not unmanageable. Of course you get much better results at a dark site.
whenever we get around to really looking at Hydra...
What telescope do you have? Would you see any of that through the scope or is it because of long exposure times?
At last! someone that have the same idea i've had for a while!
What I think is what if another life form is just made in a way our eyes cant see, heck what if they are made of dark matter and there are worlds we cant even touch due to physical limitations.
I would love to read and talk more about this. Everytime I remember I may not see anything related happen I get sad

Sorry to disturb the thread but is there any site to learn the basics of using a telescope? MY son got one as a gift (nothing really impressive) but it seems that I lack the very basic skills of using a finder, etc.
(not to mention the bad urban sky here and the usually bad weather...)
Multiple (sometimes hundreds or thousands, often taken in different RGB/wavelengths through different apparatus. Also combined with 'flats' and 'darks' that you take at the same time to eliminate the hot spots and other instrumental errors that digital sensors in cameras emit) lengthy exposures. But the post jchap linked to in his response is full of great detail.
Read about DeepSkyStacker and AutoStakkert on google for info on how that works, but it is exactly what it sounds like. And it can be done quite cheaply and relatively easily with modest equipment (though obviously set your expectations correctly - those pics taken by jchap come from time, practice and decent equipment!) Everyone who has a camera and an interest in AP should have a go at making a barndoor tracker, even a basic single arm one can allow for very lengthy exposures. But if you're handy, I would insist you build the type 4 'Dave Trott' version of the barndoor, it's sublime.
AP is a glorious endeavour. - it starts with 30sec exposures @ 200mm where you point your DSLR at Orion and discover that beautiful red nebula in your image, and ends with you scouring second hand markets looking for HEQ5's and wedges.

Knocked out a quick poem (?) about Pluto. It's a thing I do sometimes:
In my mind you existed for the longest time
as a demoted afterthought
an icy misfit
amidst the solar hearth of nickelcores and gaseous furies
A set of inert pixels that could affect nothing
could move no one
Yet here I am,
staring at your profile
beamed across billions of miles
delayed by hours of lighttime
marvelling at your heartform
wondering at your mint condition peaks
intrigued at what lurks beneath your frozen shell
drawn to the inner strength that keeps you going
allows you to dance the fandango with the ferryman across the void
I was wrong
You are alive
For only the living can waltz with the dead
Two sides of the same palm
Opposite but inseparable
Tidal locked
So while we finally notice you
toss out theories because of you
are collectively enriched by you
You care not one whit
going on as you always do
content to take the long way around
across the farthest shores
where sunshine changes to starlight
year after year
four of yours equating to a thousand of ours
No hurry
For you know your way
Through the darkness

Curious myself.
A not very technical explanation can be found here: https://www.astronomics.com/how-much-color-can-i-see-with-a-telescope_t.aspx but otherwise Google has plenty of other answers.
But basically it boils down to how the rods and cones in our eyes have evolved to be sensitive to light, or in this case not sensitive enough. There are many things in the night sky that are full of colour when you view them visually, though so don't be put off. Visual astronomy is a real treat.
Just released:
Media briefing today. More images. Maybe they'll have some theories about the formation. Geophysics! Stuff and thangs!

I have an 11 inch SCT with a 2800 mm focal length. My tracking mount is a Losmandy and has a instument capacity of 60 lbs. I use an off axis guider for full fl photography and various guide scopes for reduced fl photography. Those shots were taken with a lens replacing the secondary mirror of the SCT which makes the scope f/2. In this configuration you don't need especially long exposures for these kind of targets. These were stacks of 30 second exposures. With a camera and a few second exposure you can see everything in those pictures but it is a noisy mess. Stacking pictures up is what makes them clear and bright. With an eye piece you can see these structures but not nearly as well.
I use a modified Canon 6d which has the IR cut filters removed. For planetary photography I use a b&w high frame-rate ccd with a tiny frame and a color wheel. I also have a ccd as a tracking camera and plan on getting a cooled ccd in the future to use for ds photography.
Im really looking forward to todays image dump. For some reason I really want to see a good image of the smaller moons.

I really wonder what could make a person faint to be honest.... besides aliens that is.
Giant penis shaped mountain?

Now that would be funny.
Edi: So how many hours until we see what made that person faint? My USA timezones are a bit rusty.

I don't know what can make a person cry, cheer, or faint besides aliens.
My expectations are low.

The formations on pluto and charon are unnatural for it's location. Obviously the two rocks were placed their by ancient aliens to archive the history of this solar system.

My guess is liquid water. I thought I saw cracks in the surface on that Charon closeup.
I don't think people would cheer if they suddenly saw proof for alien life. They'd be gobsmacked.
Besides, the resolution probably wouldn't be good enough for that. Even if the aliens were 20 meters wide, it just be an undistinguishable pixel. Probably it just proves some kind of theory they had, and the fainter was narcoleptic.

It's like minus 220 degrees.

Hence the reaction.
Touche
My guess too, albeit not on the surface, it's too cold (as said above). Probably a combination of frozen H2O and tectonic activity creating underground lakes or something and they managed to find proof.

Man, why is Neil Degrasse Tyson so terrible at explaining why pluto isn't a planet?
Why not say it hasn't cleared its orbit of debris. Why not explain that if pluto is a planet, than so are many other very large objects out there, like ceres and eris.

Hasn't that already been proven for Ganymede though?
Given surface pressure of Pluto any sort of liquid would be something completely unthinkable. Either that or the atmosphere is much thicker than previously thought.

I think they found a geyser (or recent remnant thereof).

was expected even I see.

They found King Flippy Nips.
Ceres is about 1/3 of the size of Pluto, no? Eris is about the same size as Pluto, but they're all classified as dwarf planets. The video was pretty funny, I'm not sure why NGT didn't explain the difference between a dwarf planet and a planet, honestly.

A large swastika shaped building on Plutos surface?

Umm.
NASA needs to cool their jets with this announcement. What gets NASA weak in the knees and what gets the general public excited are two different things. It may be groundbreaking but I wouldn't be selling the crying and fainting. The only things that will have me crying or fainting are aliens or water.
I will pee a little if they find signs of human life.
Vapors? Well that explains the fainting.
It's just some guy getting excited on a spaceflight enthusiasts forum, not a press release or anything.

Ah. That's on me then.
