Thank you. Drawing it out helps

This is so helpful for my astronomy final! Thank you for not just defining the terms but actually explaining things.

So good, hope you make more video

Thanks for video

How far out does the sphere around the earth go is it unlimited

Thanks! I do have a question on why does the declination change throughout a year?

What is the ball in the middle? The Earth we are navigating? How do you get a 90°angle at the GP from a ball Earth? Earth is measured flat

Thank you for making this video I am studying declination

I could find the satisfactory content here and am very glad watching the content ❤

Thank you! I am taking Observational Astronomy this semester, and I had forgotten some introductory material, this helped me get back on track.

i have a phobia from space imagery, It sounds fun but yea, i needed something like that for my study project, thanks

doing my astronomy gcse and this is really helpful!

Thanks a video that makes sense, given by a person who know how to teach.

How do you account for the fact that you are never really looking at the sky from the equator?

You are really good at drawingin perspective .u may be a natural painter .give it a try.... that right ascension drawing went through the celestial sphere as it should ! And subscriber from Ethiopia right above the equator

2:10 Is this point you drew on the Earth's surface or at the Earth's center? Also, how does this change as the earth orbits the sun?

Thank you for these videos. I'm commenting in this video because the comments were turned off on the other video. You said that as voltage goes up Amperage goes up. I work with 3 phase electric motors and I've noticed that as voltage goes down the amperage goes up and kills the motor. I don't understand this given ohms law. Is this because the motor will always use what it needs to do work? Does it have to do with power coming from the grid vs power coming from a battery? 3 phase vs single phase? AC vs DC? It would be great if you made a video on this.

Rest in peace dad… love you.

Thank you so much! I'm currently reading a book on this subject and this clarified things

I'm aware this is only meant to express an elementary concept, but as long as you went to the trouble to make a whole video about it, why not take a few more seconds to include how Earth's axial wobble affects things, why it has to be vernal equinox when autumnal equinox is the same thing, and what units of measurement are used for RA (hours, minutes and seconds). You should really also consider using a script next time.

thank you so much, this video is so helpful.

It’s nearly been a year and I’m glad you made these videos because it nice to have you teaching even when you’re gone - an svc pupil

Please tell be name of this awesome pen

Thank you, I now know that the next video I want is of the vernal equinox. You should link other videos under this one ✌😉

Came here cuz i was very confused when watching contact

The video is really great, but if I have a specific star in mind, how do I determine what the declination and right ascension of that point is? I ask because I have an application that asks for the declination, and I am unsure of what to put.

There’s no explanation about RA

F in chat batty fish

Rip u lickle batty worm

RIP u lickle pussio

Waste of paper. You should invest in a white board.

Hmm so that’s how it works. Thanks :)

Thanks a lot sir, Can the Right Ascension (RA) and Declination (Dec) can be used for the astrology directly??

Couple of small points "Ascention" is spelt Ascension. "How far around" (horizontal angle) - may be better to use 'hour angle' like we do in Celestial Navigation. Beginners tend to get confused with the Vernal /plane of the Ecliptic etc. Otherwise good explanation

Which video are you referring to that describes the Vernal Equinox?

Thank you for the understandable explanation.

It’s right ascension.

so helpful, thank you sir!

Thank you! This was a much better explanation than the professor's.

So how does this work when you take into consideration that the Earth wobbles on it's axis?

Another non-explanation of RA. Don't include it in the damn description if you're going to simply refer to other videos.

Thanks you so much!!

thank you so much, this helped a lot, every other video on youtube is useless. thank you.

Loved the visuals!

thank you sir you helped us a lot.

Gary, I am enjoying your astronomy videos. Do you have a book or several books that you would recommend on the subject that explain them the way that you do?

Great and very easy explanation

Thanks
