Astronomy Magazine How To - Observe Galaxies

[stevemem1]

It's just awesome finding out about space, my interest in astronomy has grown quite a lot over the years, and I now have a decent telescope.

[TheGeckogamer]

I love astronomy.

Nice video! I am an artist on YouTube trying to promote my theory on the dynamics of light and time

This theory is based on just two postulates

1. The first is that the quantum wave particle function represents the forward passage of time itself

2. The second is that Heisenberg’s Uncertainty Principle that is formed by the wave function is the same uncertainty we have with any future event

A YOUTUBE video "UFO Disclosure A Global Deception Conspiracy "

reveals hidden awaremess of life outside Earth by politicians,

astronauts, American presidents, military personnel, along

with aired UFO news footage. This compilation contains planned

revelations about free energy technology, initiated first contact

along with current and ongoing E.T. presence which is being hidden

from the public + more.

Thats right though - These images seen here are combined and stacked, some have hundreds of minutes across several imaging sessions - This is not what a telescope will show you with your eyeball, these images are what you will get if you get into astrophotography. You guys below are right, they should make this clear. No wonder so many get frustrated with their first views...

[Jermaine123X]

Check out my videos..It's what stars really look like...

[xXSparky117Xx]

They really need to make it clear they won't look like this through the eyepiece. These are processed/stacked photos from Hubble and professional observatories.

However, if you find M42, you will see it in all of its glory with a good scope.

[guitarplayer4real]

@xXSparky117Xx I wonder if people really think they will look through the eyepiece and see the pillars of creation as they are in the Hubble shots:-p My first view through a 16 inch Dob was hardly disappointing but I wasnt expecting to see a color HD image lol. Took me over 12 years but I'm pretty happy with what I can capture with my modest backyard observatory. I guess I have about 7k invested but need 20k - Taking donations for new scope and mount:-p

[Sadek1984]

Bastards show Hubble images and talk about backyard observations - and what you see in the EP is usualy a blurry spot in the darkness of the sky.

My girlfriend gave me a cheap telescope last year and after playing around with it a few times, I've been bitten by the bug again. Plan to buy a kit and get started building a big one. I live way out in the boonies so light conditions just a few miles out of town will be quite good. Might even buy a trailer to haul it out there. I'll keep it lo-tec so I can spend on the optics. Any suggestions on where to start?

[thedoctor69able]

oh when it said astronomy i thort it meant ass stronomy

[hiian123]

Thanks a lot ill really need this info cuz ive been starting to look for some galaxies with little luck! Unfortunately i have a small meade ds2114 4.5 inch goto starter scope that really limits me especially in our suburban light polluted skies! Im going to step up to a 12 inch meade lightbridge, get some premium meade series 5000 UWA 2" eyepieces, a meade telextender 2x 2'' barlow, and some nice filters! (prob the zhumell 2inch set) thanks wish me luck! Happy veiwing and cheers!

[TheSMITALIEN]

awesome clip

I love astronomy

this video is very good!!!

[ParaglidingManiac]

Graet tour!

[seekfears]

google Doe's Account.

[Razmik93]

we are not alone in this galaxy! )))

[dunbustin]

Excellent clip. 4" (100mm) scope, dark skies; now we know what we're gunning for. 70mm scope and skies that resemble orange soup, me.

Is it just my impression or is light polution getting less? Perhaps the air is be getting cleaner and not reflecting the light so much .

[blgfan97]

The "denser" space is, the slower the time passes in that region of space. Space is "denser" near gravitational bodies such as planets, stars, and black holes, so time passes slower the closer you get to them. In intergalactic space, time passes many times faster than past the event horizon of a black hole, because space isn't nearly as "dense". The more space, the slower the time, and vice versa. To be able to locally speed up time would mean reducing light years to miles, allowing FTL.

[nickharvey7]

Interesting video and great photos!!

767,17 Kpc away from us...that's far!

[ItsOttis]

whenever this guy says galaxys I cringe

[hongcha300000]

I love this guy's voice. he makes the information more interesting and attentive.

very informative video , too. cool.

[suchanawesomekid]

how can such a primitive industrial civilization like ourselves can have any knowledge about anything??? hahahha

excellent video tho :)

[wilkopilko]

So true, this very question just popped into my head just before I read your post!

Great stuff - makes everything on Earth look so insignificant.

We are mites on a grain of sand!

[dvamateur]

Enough knowledge to sell the magazine. Everything else is unimportant.

[smashbroslover73]

Awesome..

[stars270]

very cool and amazing!!!!!!!!

[EGMAG]

How does telescopic magnification work? If we were to observe the sun and it went out for a moment; does a telescope observe that moment at the sun surface, time zero; or time 9" plus, at the lens surface of the telescope?

[peteq1972]

you`d see the sun go out 8.3 mins later, it takes that long for the light to travel. Same with gravity.

We see Andromeda as it was 2.5 million years ago cos it`s 2.5 million light years away. A lot of stars are probably not there anymore but we still see them because the image comes from so far away. i find that facinating, we`re actually looking back in time.

[EGMAG]

@peteq1972 back in time. <<

Think about this. You are looking at the present time when that light reaches the front of the telescope lens. As it continues to travel at the speed of light the lens shows each second of present time although it looks as it was; the way that object really is, is changed over 2.5 millions of years, if you were there and not here. If you were to travel there to Andromeda time would still be aging it and new changes would occur every second of the way to there.

[peteq1972]

Wow i know, it`s mind boggling. if you could travel faster than light you could be there, travel back here, look through the telescope and see yourself :-/

[EGMAG]

@peteq1972 see yourself <<

Interesting take on it. Although you may only be able to see a blur that is faster then the speed of light.

[EGMAG]

@peteq1972 faster than light <,

This in no means effects time, You only see what appears as the past; as time just keeps trudging along. No real way to measure time. Time is now measured by particles or increments of light from a to b. A light-less universe, would still have the same constant of time passage regardless of any light or sub-atomic particle physics! This is the time paradoxical phenomenon faced today that crushes all other theories of origins, metaphysics & physics at their core!

[peteq1972]

You go back in time if you exceed light, though anything with any mass cannot reach the Speed of Light. if there was no sub atomic particle physics doesn`t that mean there would not be matter, no stars etc. Not even subatomic particles interacting to make atoms - No events happening - time stops?

[EGMAG]

@peteq1972 No events <<

Who said there is no sub-atomic particles? Not me. I said the measurement of time like atomic clocks uses them. Time never stops, ever. The observances of events changes. Time is still existing forward even traveling at c. Without matter or events time still exists. Scientist think time must be at zero. Even the mathematics concerning the motion of matter and objects is flawed as it appears to indicate time at zero. However it is not at zero!

[peteq1972]

"Without matter or events time still exists."

No it doesn`t.

Time is not a constant, time passes more slowly the closer it is / or you are to a gravitational body such as the earth. Time passes faster in space, this HAS to be taken into account or your sat-nav or satalite tv or anything using a satalite to work, not to mention military. i don`t know what you mean by "time at zero"

sorry if i`m getting the wrong end of the stick here

[EGMAG]

@peteq1972 No it doesn`t.<<

Time is independent of gravitation. Your light measurement, c falsely entwined with time, interprets time, gravitation & space as interdependent. Of course it is all you have for the moment to come as close as you can to minimize the inaccuracies. By time zero or t-0, means 0 to the fraction of time when the alleged Big Bang started. BB must obey the action reaction laws; proving a pre BB, where time also existed, although immeasurable, forming into the BB.

[peteq1972]

@EGMAG Proving a pre BB? PROVING? stop right there, lol.

[EGMAG]

@peteq1972 Without matter or events time still exists<<

Because even in nothingness, and the absence of all events, the non-physicalness of time is unaffected. Because time is something that when measured by physical events becomes a believable illusion of objectivity, or of matter. If you traveled backward in time to see yourself, as you hypothesized; time would still be going forward at its same immeasurable pace. You measure time by physical constants. Time is unaffected by the physical.

[EGMAG]

@peteq1972 anything with any mass cannot reach the Speed of Light. <<

Ahh, wrong. Light being physical with wave and particles [too small to be detected] has mass. Light can bend only because it has mass of some undetected type. A light photon with mass, travels at the speed of light c and defies the Lorenze theory. It is not time that stops it is the instruments of time measurement that assumes time stops and are observed mathmaticaly and instrumentaly.

[AFVABMDES]

Excellent!

[jamieball]

I have a 4" skywatcher but I am still having trouble observing the galaxies in ursa major.. I am in the city but sometimes the viewing is not bad. I am very excited to view the Andromeda this summer! Thanks for the informative video

[Emm0r]

do you have any tips on how to spot Andromeda? Trying to do it myself, also experienced alot of cloudy skies recently so it's not looking good :(

[pitcalco]

It is quite challenging to see other galaxies in spite of all the encouragement in this video. Personally, I find if there is any amount of moon above the horizon (i.e. anything other than a new moon) it will drown out any galaxies.

[Coloante]

cool

[najimartial]

the one who created this must be so great and omnipotant.

[thebutler89]

omnipotent

[calypsocoffee]

I like very much astronomy
