Thanks for disappointing me. I came here expected this to be yet another boring and confusing TH-cam 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!
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.
@@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"?
@@jimmo42 Well, you write positive feedback to the kind TH-camr, 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.”
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.
@@peakart8850 Google "sarcasm and intelligence". That might explain the problem you have understanding.
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.
After listening to this guy....I'm getting spaced out ~
Yeaaaaaaa
Nice one
This guy: no one lives at the North Pole.
Santa: Am I a joke to you?
Lol exactly. You are a joke
loool goddamit #santarights
That's a good point, where do flat earthers think Santa lives? More evidence they will dodge.
lmao
the war on Christmas!
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.
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.
What a great video! Thank you for posting and keeping it simple! I am 51 years old and received a telescope for Christmas and trying to learn the basics before I attempt to use it!!
Wow thanks for that! I couldn’t put into words what I was thinking to explain to someone what I was trying to understand. And the simple words of “getting oriented with the night sky” sounds so basic but is powerful thanks! 🙏🏽 🎉 🌎
thanks so much! i have my astronomy gcse tomorrow afternoon and i really didn't understand declination and right ascension until i watched this! many thanks from the UK :D
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 TH-cam too.
I love your videos. So well at explaining things precisely and clearly. Thanks :)
Awesome videos...Highly appreciate your efforts in making these...
You're welcome, and I'm glad that things "clicked" for you! :-)
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. Finally found your channel & hopefully watch more videos from your channel. Added to a playlist: Astronomy, cosmos, universe. Thanks again from Great Britain.

Went from my 11PM to the 15PM in natural. Love it. Awesome bit of kit.
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!
Do you still love it? Cause now I'm 16 and I can relate to you
Awesome videos bud. Keep them coming learning something new with each video. Thanks again.
Great video sir, my daughter and I watch this 3 videos 3 times each.
Really enjoyed this video. Informative, straight to the point and with a friendly disposition, and fine graphics to supplement the info given. Grade A quality. Thanks!
Thanks. This explains whole lot for me. As in Contact . Jodie Foster was talking about right ascension and declination :) I had no ide what she was talking about :) Ty
Excellent video, thank you. A true astronomer! Wearing a comfortable black hoodie while presenting an instructional video to thousands of viewers.
You're welcome! It's better to be laid back, the way I see it. :)
David,
I am just getting into astronomy and found your videos. They are truly awesome, thank you for all the obvious hard work you put into them. Watching the sponsor's ads in full in the videos, thanks.
Xsheaffer thank you so much for the kind and generous compliment!
Always refreshing to see videos like these from you.
David, David, David! Thank you! Now that was the best explanation and presentation I have seen on this subject. For a little over a year I've been heavily into astronomy, reading a lot and even trying to make sense of this Coursera (Duke U.) Into Astronomy Course, and you really nailed that for me. Thank you!!!
You're welcome John - glad I was able to help!
Absolutely fantastic video. Exactly what I was looking for
Thanks for educating and getting me really started on star gazing...this is very nice n clear explanation. u deserve full marks. you can load more videos on this topic & astronomy in general
Thxs for your videos, I am a novice and just purchased my 1st telescope and I am clueless , but your videos are of grt help
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!
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? :-)
Hi Charles - thanks for the thoughts. I guess I look at this way: In the story of the tortoise and the hare, the tortoise won. Maybe comparing myself to a tortoise isn't the greatest one to make, but the point is this: Over time, the views will go up. That's what matters. I'm not worried. :-)
I'm sort of late to the party, but I just wanted to take a moment to thank you folks at eyes on the sky for all the helpful information!
Superb information video Dear ❤️... Thank you for sharing 🙏❤️
Hey man thanks for these videos. they are really helping me figure out this RA and declination. I appreciate it.
oh wow, i can't believe I missed the "night sky part" .. i understand it now. thank you sooooo much!!.. more power to you!!!
I just discovered your videos, and I find them truly educational. Thank you for preparing this content to teach to us. I'll keep studying.
Thank you for your kind and generous compliments.
Nicely explained subject with very good graphics.
Good job Mr David, keep it up.
Iv always loved space since i was a kid, its one of my main interests and i want to learn the constellations and how to star gaze thank you!
I just got a telescope today and spotted your videos.
You Da Man!
You Da Man!
Will use you every time for instructions and help.
I like that he used stellarium !
Boom this is exactly what I was looking for, thanks!
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.
SO clearly explained! Thank you!
Just watched basics 1 through 3, I've had a Eureka moment, thanks, really enjoyed (and understood) the vids.
I can't find Basic 2 or 3. Please help!
Nice and simple. Now I can buy an Accurist Celestial watch, and begin by understanding the lines!
So um, I had done an astronomy crash course about 5 years back. Wanted to get back into star gazing.
Thanks for making this video. It is truly amazing
You're welcome - thank you for the kind comment!
This series of videos is awesome, thank you! Starting from here.
Says the guy with a Illuminati pyramid as his pic
Amazingly helpful. Thank you!
You are the best...
Keep it up...!
Good idea to outline the basics for beginners.
I gotta apply practice thanks for this David.
Couldn't be explained any clearer. Crisp and clean without assuming anything about the viewer which is a rarity!. Thank you for taking the time to make these. .
That is one of the nicest compliments I have ever received. Thank you so much; I work really hard to explain things clearly without talking down to viewers.
Very interesting. I have Star Chart for iPad, and have always knwon a BIT about Right Ascension and Declination, but now I understand it more.
'Thankyou" for knowledge and video.
All you explain is korrekt and we use it in this way.
Excellent!
I know what I'm doing tonight :D
fantastic! I teach Astronomy and your videos are great to prep and share.
Thank you so much! I think others who teach astronomy refer to them too, which is both amazing and humbling.
Excellent video, learning this stuff just for fun and taught a lot.
Thank you David ! .nice videos !
Great! This is amazing! Thanks so much!
You are very welcome - thank you for watching.
Hello Hello Happy Holidays! Thank you so much, wishing you the same. We hope this season ends on a joyful note and continues into a safe and prosperous New Year for you and your Family.
Thank you Sakura! Happy holidays to you as well.
This is great ! I studied physics some years ago but never had a chance to get into Astronomy. Now I'm hiking in the wilderness more and wanted to appreciate the night sky better.
Question: Can I use the position of Polaris, to determine magnetic declination for normal daytime compass use ? Seems like one could do that.
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
Enjoyed your explanations on telescopes. I did bump into a little serious Astronomy, after I created DIY Barlow Lens for a Dime, took some moon shots, now I am trying to observe crescent Venus with this...there is a bit of aberration issues. I should be able to resolve it I am sue. Do find my moon shot with my own DIY telescope and J6 plus mobile. Loved your channel, continue inspiring the world..........myself an architect, musician....!!!
👍Your videos are very helpful and easy to understand. Thank you!
LovingAtlanta that's very kind of you to say, thank you!
This is a great video.. Thanks
Excellent video!!!!
Loving the content
Greate work,like it.
Super video❤️👍
It's a very useful video. Thanks :-)
Great video, thanks! Noticed that E and W are swapped in your visual that explains the zenith, ecliptic etc.?
Great help! I'm going through an old stargazing book and its nice to have a little video to supplement
Glad it was helpful!
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 😢
Very informative and helpful. Thanks.
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.
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.
I just had an epiphany! Did you feel it? Excellent series. Until I found you, I would point my scope at something (the moon) and focus. It's a learning process but my goodness, your explanation makes it seem like I am a real astronomer. My friends think I am a half a bubble closer to being the cool buddy. Tonight I got a big surprise for all the mosquitos! Nobody told me about that part in the telescope store... 8-) I got eaten alive last night! A friend said turn on a fan, I hope it works.
Great Video
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!
so how exactly do i calculate the suns position at any given hour using DEC-RA?
Thank you for making this video
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?
your videos are fantastic!
Thank you. Very helpful.
Awesome video man
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!
hello david, would you recommend me buying either of these for a beginner star gazer... Bushnell Barska
Starwatcher 525X Reflector Telescope or
Pacifica 10-30x50mm Zoom Binoculars ?
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.
Hi sir any different in latitude when we measure it on sea and same on earth from north star
wow this is incredible
Absolutely fantastic
The intro music is very good where i get the full version?
Great work duder, this is really helpful.
Thank you!
Very well explained! 😉
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.
"The ra and decl.s are always changing...how can they have fixed coordinates?" Because Earth is rotating. If you took a rocketship out into space and then sat, unmoving for example, the stars wouldn't move, but Earth would be rotating. So the RA and Dec only appear to change to us b/c EARTH moves (rotates/revolves) and we're along for the ride which causes the stars to rise/set, but they're actually fixed in their points in the sky. Make sense?
Great video! I really liked your enthusiasm and simple explanation. :)
Soumya Rossiter thank you!
GREAT 👍
Liked #withsubtitles in your description.
Though good video!!👍👍
ok, i think i pretty much get it, but how do the coordinates of any object stay the same as the earth rotates? wouldnt they change since the coordinates are projected out from earth? thank you for the help
