Getting oriented to better learn the night sky: Stargazing Basics 1 of 3

[@jimmo42]

Thanks for disappointing me. I came here expected this to be yet another boring and confusing KZbin video. I was disappointed. This is well presented, you speak very clearly, and the information is useful and coherent. Admittedly, I already knew almost everything you said having been an astronomy buff since the 70's, but it was definitely a wonderful review of the basics. Keep up the great work!

[@peakart8850]

Uhh, I believe the word you’re looking for is, “impressed...” You were saying, “disappointing” as if you were saying the video was bad, not good.

[@jimmo42]

@@peakart8850 uh...nooo..... Seems you have misunderstood what I wrote. What was I expecting? Did I get what I was expecting? Or did I get something I was not expecting and thus was "disappointed"?

[@peakart8850]

@@jimmo42 Well, you write positive feedback to the kind KZbinr, but yet you say you are disappointed. I just may not be hearing you right, but if you were expecting a bad video and was surprised to see it was well presented and that the man spoke clearly, then the correct word would be, “impressed.”

[@peakart8850]

And the definition of the word, “disappointed” is that you were expecting more of somebody or something, but did not receive that level of expectation.

[@Eyesonthesky]

Thanks - I figured there are some folks who are interested, but don't know how to get started and may be afraid to ask. This way they can get the basics of the terminology, where and how to look, and then ask better questions. I'm hoping that astronomy clubs may find these useful to put on their websites too, as it should help beginners get basic astronomy questions answered so newcomers will feel better informed.

[@grinwicked5132]

Excellent video, thank you. A true astronomer! Wearing a comfortable black hoodie while presenting an instructional video to thousands of viewers.

[@Eyesonthesky]

You're welcome! It's better to be laid back, the way I see it. :)

[@Eyesonthesky]

You're welcome! Remember, the zenith is different depending on your latitude (and not the same as the celestial north pole); it is the point directly over your head, no matter where you are on Earth. So nadir is directly down through the ground, wherever you are, and won't point at south pole unless you're at north pole. Altitude is degrees above your own horizon; azimuth is the direction "around" that horizon. Download free program Stellarium; bottom tabs have most of these listed.

[@Vladdie777]

Thanks dude, I'm trying. Started stargazing as a kind of therepeutic thing with some binoculars. I do struggle to orient myself, sometimes I can easily spot constellations when I'm lying down, then I move around and look up and it takes me ages to get my bearings again. This should help with that. It's really cool though, feels like I'm reconnecting with my ancient ancestors and the universe again, we are all stardust after all. It feels great to learn the constellations, once you can see them properly it's like your painting the night sky with your imagination.

Posted eight years ago and still replying to comments, what a chad. My town uses the wrong lights so there's lots of light pollution. Terrible shame because the night sky is so beautiful, still helpful for what I can see. Thanks!

Maybe one day we can get everyone to turn off the lights together, and the world will see the wondrous cosmos that is usually hidden from their view. Ah well, probably not - but I can dream! Cheers and clear skies.

[@erichowry9356]

First time here! I am an amateur astronomer and excited about learning stargazing and using my telescope.

[@Eyesonthesky]

Thank you Jim. What I was thinking was astronomy clubs might want to put them on their websites, to help people get oriented in the night sky, so they feel more educated if/when they show up to outreach events or meetings. But I also use them to supplement my own live presentations at libraries and park districts, because I cover the same concepts each time. This way people can review them at their leisure on my website or on KZbin too.

[@reddeadghost4343]

Im 15 and my love for astronomy i had as a child is starting to grow again. Ive been looking for information about the planets and the night sky for a week now , have installed an app to help me too. I'll buy a telescope in a few months when im completely ready!

[@TheVinster177]

Thanks for this. I'm taking an Astronomy class next semester, and this helped me wrap my head around the concept of the celestial poles. I never knew stars rotated in the sky though, I always assumed they just went from East to West like the Sun. Interesting stuff!

[@Eyesonthesky]

You're welcome. Remember, the stars don't actually rotate; it's Earth rotating that makes the stars appear to rotate over our heads. And they do go from east to west - it's jut the ones closer to the poles go in a circle. Well, they ALL go in a circle, because the Earth rotates! Make sense? :-)

[@DifferentSaturner]

Excellent! I liked how you explained everything clearly. I'm interested in this subject but I was often fooled by fake, not-so-clear, clickbait videos.

I am a little bit confused at 1:05. I've tried marking it out on paper then raising it over my head but it didn't make any sense. i thin that N,S,E and W are all inverted but I don't know. could you please explain David, it would be highly appreciated.

[@Eyesonthesky]

Download the current sky map here www.skymaps.com/downloads.html It has E and W inverted too, for good reason. Held over your head, with N and S in the correct orientation, E and W are then correct. They are wrong when looking down at the ground. But that's not a map of the ground (down), it's a map of the sky (up).

Wouldn't the sun be lower in the sky during the winter and higher in the summer? I think it was said the other way around in the video.

[@Eyesonthesky]

During the day. BUT... the ecliptic at night is opposite. Think about where you are on Earth when it is dark, so the Sun is low during the day in winter, yes, but then the ecliptic is high overhead at NIGHT in the same season. Opposite for summer. Because you're tipped the other direction from day to night.

[@rajibjoshi8868]

being familiar with globe ( earth ) including longitude and latitude having basic idea of earth rotation and earth"s path around the sun and moons rotation around the earth I picked up on what you described as CELESTIAL SPHERE and the idea of ZENITH and fundamental movement in sky of stars and planets ( same as sun- E to W ) good basic lesson my next step is to understand declination and ascent later

[@ecnldad9471]

Hi David, your videos have been extremely useful in my pursuit of astronomy with my daughter. About 3 years ago I purchased Meade LX-200 10" (Schmidt-Cassegrain) with an AutoStar Upgrade and GPS. Also, I have an Equatorial Mount. My biggest issues (still today) is aligning my telescope. While I can find Polaris I'm never certain if the Stars I'm aligning to are the correct Stars. Hopefully, I've solved this problem is an iPhone App called StarChart. It would be a lot easier if I had a local club, but unfortunately thats not possible.

[@Eyesonthesky]

Andrew Beau set your mounts latitude to your latitude, level the telescope as best you can, and aim generally as close to north as you can eyeball it. That's good enough for visual observing. I have some videos on aligning and aiming equatorial mounts; check my channel. Not ideal for a fork mounted scope, but still might help.

[@sinjunart49]

Great help! I'm going through an old stargazing book and its nice to have a little video to supplement

[@Eyesonthesky]

[@gauravnath]

Great video, thanks! Noticed that E and W are swapped in your visual that explains the zenith, ecliptic etc.?

[@bumb_blet1593]

Can you please explain how the northstar can be fixed in the same spot? and how come all the star constellations are the same and moving in the same pattern since the beginning of the earth as we know it? Shouldn't we see new stars all the time since we are speeding around in the universe after a moving sun? Or are the star constellations we see moving around the earth? While the earth is moving around it self and at the same time around the sun that is at the same time moving through space? I would really like to get a intellectual answer on this and also on what real scientific proofs we have of this?

Thanks to you i could visualise this scenario, as i am not able to witness the night sky with my own eyes due to the pollution and my myopia 😢

[@yuridanylko]

I don't understand 4:07. How can right ascension and declination both run from the celestial pole to the equator if right ascension moves along the equator?

[@yuridanylko]

What I mean is, ascension runs along the equator on one of your images and then it runs perpendicular on the equator when you go to the starry sky image. Were these mixed up?

[@Eyesonthesky]

@@yuridanylko think of right ascension as being like longitude and declination like latitude. The difference is that RA and Dec are projected onto the sky instead of being on earth. Does that help?

[@yuridanylko]

@@Eyesonthesky So the first image was wrong and right ascension goes from the pole to the equator straight down?

[@MC5yntax]

Can you clarify if this is the same or opposite for southern hemisphere?

[@Eyesonthesky]

If what, specifically, is the same or opposite for the southern hemisphere? I just want to be sure I am responding to what you need clarified. Much of it is the same, but Right Ascension, for example, is reversed in the southern hemisphere (so it's really "Left Ascension" I suppose).

[@johanvanwinkel8590]

Ok. how come east is now on the left and west on the right? Day time looking North, East on my right and West on my left. WTF????

[@Eyesonthesky]

Great question; it's because you're thinking in terms of a map, which we humans look at from a "top down / birds-eye" view. But the sky is up. So imagine this instead: If you could take your computer monitor or screen, and hold it up over your head, with north behind you, and south in front of you, the E/W relationship becomes clear, as they are now on the "correct" sides. It's when you look "down" for a sky that is actually up that cause the confusion. Make sense?

[@johanvanwinkel8590]

thank you, now i know

[@Eyesonthesky]

Johan Vanwinkel you're welcome. That's an easy one to look at and wonder what the heck is going on until you orient things overhead for the sky, then it makes sense.

[@pfscpublic]

Eyes on the Sky No, it's not making sense. If I hold the screen above me, what am I looking at and where is my point of view looking? Is there a good graphic url I can look at?

[@Eyesonthesky]

Paul C Hi Paul - download the latest all sky star chart from skymaps.com, print that out, then face south. Hold the chart in front of you. Then lean your head back, and bring the chart up over your head, so north will be behind you/"up" on the map, and south still towards your front / at the bottom of the map. East and west will then be correct. But if you turn around with the map held below you (like a terrestrial map) and north at the top/south at bottom, looking down at it (not over your head), east/west will appear reversed on the star chart compared to actual directions. That's because the star chart if for overhead, not viewed from a 'birds eye" perspective. Print that chart, try that, then let me know if you still don't understand. :-)

[@zoespeshington2401]

Hiya, great vid but I think I got a little confused. You said RA starts in Aries but on stellarium Aries is at the 2h line. Did I miss something?

[@Eyesonthesky]

Good catch - I should have been more precise about that. Due to precession, 0 hr RA is no longer in Aries,though we still vall it "The First Point of Aries." It started there, but the Earth wobbles on its axis over 26,000 years, so the point where 0 hr RA is has changed over time.

[@zvonkovuk3206]

Oh, thanks God! Finally something easily understandable!

[@DarkMoonDroid]

These are 3 totally different coordinate systems that are used together to track the movement. One system is oriented to the viewer, one is oriented to the planet and the other is oriented to the zodiac - or the ecliptic plane. It's too complicated to think of them as one system. Here's a 'nuther way to say it: Say, you're in a car driving around the block to go to the 7-11. You always go the same way. You pull out of your drive way and turn right (in 'Merka, or left in the U.K.). One system of orienting yourself is to look at what you are passing as you drive by. You see your neighbor's house, the house with the big scary dog, the house on the corner, the real estate office, etc. You pull into the parking lot at the store, buy some gum, then get back in the car and pull out again, turning right and drive the rest of the way around the block, passing the tattoo parlor, the crazy cat lady's house, your other next-door neighbor's house, and then pull back into your own drive way. The coordinates of the stationary or "fixed" things never change - but some people, animals, vehicles, etc. move on their own, so their locations will change. Another system of orienting yourself could be a grid system painted on your car windows, oriented to the car. So, there is a vertical line down the center of the front windshield, one vertical down the center of the back windshield, two in between the front and back side windows - maybe on the door frame - and a fixed number of lines between all 4 of those lines primary lines. Then there are horizontal lines going all the way around from the bottom edges of the front windshield, the right side windows, back windshield and left side windows; and several more horizontal lines at fixed intervals above that bottom one with the last one at the top - each all the way around. All this makes a grid pattern that is a bit warped due to the shapes and slants of the windows, and each passenger in the car will have different coordinates on this grid to locate what they see. Another system of orienting yourself is a similar grid pattern painted on a pair of goggles on your face. This system is oriented to your individual field of view. Even if everyone else in the car were to be wearing the exact same pair of goggles, they won't see what you see. No one will. And as you turn your head around, or sit in a different seat in the car, this will change the coordinates of what you see. Against these grids, you can locate stop signs, people walking and cars passing on the other side of the road, etc. as they move or don't move - *but they all move relative to you as you move.* Each of these systems has their own language and symbols and number system. Now, use all 3 at the same time. That is what is going on here. It's crazy awesome!!! 🤓👀😵🧠😁🌌🌞

[@mikegordonbrasov161]

¿Any idea how to locate the first aries point from any place you are on earth? Is for the purpose of practicing. Maybe some DIY clinometer gadget, that help me to locate where is the vernal point, and after that, finding a star by it´s declination and AR? Or maybe a simpler method?

Since when on a compass has East been on the left and West on the right. Am I missing something here or has earth's magnetic system moved?

[@Eyesonthesky]

Imagine lying on your back to look up at the sky, with north above your head and your feet to the south Which side is east? From that perspective, it IS left. Because a map of the sky is for what is UP, whereas a map of the ground is looking DOWN. It's all about the perspective. It is confusing at first, but when you think about what you are trying to see and where you are looking, it makes sense (hopefully).

[@petemason57]

@@Eyesonthesky Thanks for the reply it makes sense now. Still a strange way to show stars laying on your back. Sure, does not help me find stars. Thanks

[@JuteTwine]

@@petemason57 Yes, the Earth's north magnetic pole has moved and is in motion continuously, afaik. Declination, or magnetic variation, is the name for the difference between the northern hemisphere's magnetic pole (which is a south pole magnetically) and geographic north, defined dynamically by the Earth's axis of rotation. There are also two geomagnetic poles defined ideally as if there were a powerful bar magnet in the Earth's core. Their north and south poles are antipodes on the Earth's surface, but rarely (or never?) coincide with north magnetic and south magnetic poles. These too are moving around.

1:53.... am I missing something or did you say the ecliptic is 'lower in the sky during summer and higher during the winter" ? Isn't it the opposite ?

[@JoeGancher]

OK never mind...already challenged and you are right ...IN THE NIGHT SKY....Interesting....I never saw that coming.

[@Eyesonthesky]

No, it's okay. I kind of trailed off a bit when I said it, so it isn't as forcefully stated as it perhaps should be. But it's a good question to ask, and besides, now you know!

Good night! before everything I want to say this is a really nice work, I started reading about the sky and watching it just a week ago. I have one question, do you have a video about how to get the best of my first pair of binoculars? Just ordered 10x50 binoculars and I really want to get the best of them. Thank you beforehand!

Hi David, your videos are amazing, they're helping me a lot for my astronomy class. One thing though, you said that the ecliptic is higher in the sky during winter and lower during summer... did you say that because you were in the south pole? I'm kind of confused.
