If you dislike the video, can you please leave me a message explaining exactly which aspects of the tutorial you found lacking. I put quite a bit of work into this tutorial, so any feedback is appreciated.
Great video and definitely very well put together sir! But perhaps it would be even better if you could adjust your pace a bit? Information density is quite high at times and important clues are served at record speed. But great work! No doubt about that 👍 thanks
Hello Vegard Eide, apologies for my late response. I’m glad to hear that you enjoyed the video, and I also agree that there are definitely pacing issues. Another viewer commented that viewing the video at 0.75x was preferable. I was a bit worried about the length during production, so I went a bit overboard with the speed. In retrospect, I should have split it into two longer videos. Thanks for commenting; I always appreciate feedback in order to improve future videos. Cheers!
@@RickHoefer89 I agree with Vegard Eide's feedback and suggestions. Playing back at 0.75 speed is very helpful, Thanks Rick for this superbly done video tutorial. Awesome job!
Thank you for your kind compliments BALAJI R S. I put a lot of effort into this video, so it’s nice to know that it is appreciated. I think celestial coordinate systems are probably not a very popular topic on TH-cam, which maybe the reason for the low view count. Thanks again!
Thank you very much for your kind compliments Monsoon Groover. It took me about 8 months to create this video, a majority of which was dedicated to triple checking all the math and designing all the graphics and text overlays. All of the images with the blue/grey gradient were created using FreeCAD, while the simulated projections of the night sky were made using Stellarium. Usually I would screen shot or screen cap the program in question, then import the image(s) into GIMP to align them and begin tracing them using paths. If it was a video overlay, I would crop it down in iMovie and then screen shot the full screen play black to use as a template for the transparent overlay. Next I would use a free equation generator and create PNGs of all the equations I planned to use, then import it into GIMP and merge it with the standard text. Then I would perform a process which expanded this layer and bump mapped it to give it that interesting bevel effect. I also did this with all of the geometry used in an overlay. I’ve been kind of procrastinating in starting the next video because it is a rather lengthy process, but I’m planning on getting around to it soon. Thanks again!
Thank you very much for your comment fepilo, I really appreciate your feedback. I tried to break things down into understandable sections and build on them. I have come across some astronomy textbooks that make the subject much more difficult than required. I think I may have been a bit too detailed with the calculations in topics such as the Julian Day System and calculating GAST. However, I figured that these were topics that astronomers would need to be aware of in order to understand the conventional systems of celestial coordinate systems. Thanks again for your input, it makes me happy to know you enjoyed it. Cheers!
Amazing video. Thank you for putting this together. There is so much information that I am having to watch it and take notes a couple of minutes at a time. Question, would you be willing to do a video of how to calculate a helical rising of a star at your local latitude. I want to know how to calculate a stars helical rising, but I get lost in knowing which formulas to apply.
Hello Negative Blue, thanks for your comment! Im glad you enjoyed the video, it took me about 8 months to compile all the info I needed, check all the math, create the images and graphics, etc. I consider my astrophotography series to be my TH-cam magnum opus haha. Cheers
@@RickHoefer89How are you doing now? Hope you are well. Thanks for this work. Throughout the video, I was thinking that you must be an expert in these things. It's definitely not an easy feat to make this video. And this would have been the greatest Astro geometry video if you have slowed the pace of the video. This is definitely 15 videos worth of material all crammed into one. I understand everything you said, but it took me a lot of time to come to this stage. Definitely, this is your Magnum Opus.
Thank you for the enormous effort that you put into making this. It is concentrated of almost 4 hours Uni course. really well-done. For the people who find this fast, you can use slow mode, concentrated topics are like concentrated food, it expands by digestion. Unfortunately I believe, you already give up making videos as your last video is for couple of years ago, that's really sad. I am really greatful and I do appreciate your effort. Thanks.💐
Apologies that it took me so long to reply. I really appreciate your comment, it really means a lot to me. I’ve been regretting making the video so condensed and fast-paced, so it’s nice to hear from folks who don’t mind it as much. I took a hiatus from making videos, however I’m thinking of making some more. I might hold off on the Astro videos though, I’m such a perfectionist that it takes me a long time to triple check my work. This video took about 8 months between writing and recording. Anyway, thanks for your comment, cheers!
Awesome explanation, I wish you talked a little slower though. But I like how this video is like a summary of everything you need to know about coordinate systems in astronomy
Well done, thank you. Its called the celestial equator , is that the same as the galactic plane ? Its called the Ecliptic plane , is that the same as the solar plan ?
do you think you could talk any faster? making sure we can't possibly match what you might be saying to what we are almost seeing in the graphics? might have been interesting but i can't be sure.
¿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? By the way, i like your tutorials, they are verry good!
It is good. But little hard as it is fast. I know you covered maximum. But for beginners or new person they should read something more to get to it. Great effort...
You know the reason. He rendered the video too fast and more importantly, it's 1.5 hours long. Also, these topics do not attract that much attention on TH-cam.. only guys who do PHDs and professional astro enthusiasts will look into this stuff. But regardless, we should be grateful to this person.
Watched the first 4 minutes and then couldn't keep up anymore, you're simply going to fast, explaining all the concepts in rapid succession, without a pause. I guess it's easy to follow for someone who already knows all of this, but it's difficult for the newcomer, so which audience are you actually targeting? I feel i have to go read and watch other material before coming back and attempting this video again.
The content and the idea are good but the speed of delivery and the amount of words are not helpful in understanding the coordinate systems. Certainly someone new to these terms will not be able to follow the rapid fire of the terms. Also too many examples saying repeating a concept are not needed which will reduce the need for rapid discourse.
You talked way too fast, and it is hard to keep up. You lost me after 2 minutes, even though I had viewed similar videos earlier and was just trying to gain additional understanding and knowledge. Basically you were just reading, rather than explaining.
The more I listen to this video the more upset I get. I simply can't understand how the speaker can think that anyone other than someone who already knows this stuff could possible follow him - HE TALKS TOO FAST, MUCH, MUCH TOO FAST.
Learning takes time , suggest making slides of his diagrams and print them out, watch the video again and stop to make note of what you do understand and or questions you have, watch the video again and you'll find peace in your new knowledge... Or not, perhaps the subject matter is not for you to care about, for instance I don't like country music no matter how I've tried.

I wonder why this video is only 7.5k views...Awesome work .... Graphical works and coordination of them are excellent

Just found this vid. Great so far, plan on watching when i get home. Thanks for doing this.
thanks Rick , this video really helped in answering some questions I had , very clear explanation . thank you
Excellent, best video I've seen that explain this topic, and very useful to understand your local sky and plan your observations.

Good explaation..please give a formula to find exact planet position , how to use ra and declination..
Well done, thank you.
Its called the celestial equator , is that the same as the galactic plane ?
Its called the Ecliptic plane , is that the same as the solar plan ?

Or maybe a simpler method? By the way, i like your tutorials, they are verry good!
What I need to do is calculate the R.A. at my local meridian given my local Longitude, date, and GMT?
I am wondering if you did the tutorial for people already know the subject or for people who want to learn. Next time go faster.
It is good. But little hard as it is fast. I know you covered maximum.
But for beginners or new person they should read something more to get to it.
Great effort...
More videos Please
...soooo...what happened to part 2...?
