Very helpful and entertaining for understadning basic concepts. Thank you!
This video made me want to learn more, massive thanks to you for making this accurate and educational content ❤
You are a wonderful teacher!! I have always struggled with the magnitude thing. You nailed it into my brain in 6 minutes. Thanks for your work Jenna!
Try hers are great videos that make my idea across to other people as I explain thy e night sky 🌌
Great, informative video, but it's one that reminds me I'm simply a stargazer rather than an amateur astronomer. Celestial mechanics and categorization go straight over the top of my head and I'm actually ok with that. But again, great video.
The concept of a specific distance for absolute magnitude was lost on me during reading many astronomy articles over the years. It wasn't until I purchased a telescope in the 2010s that I started looking for better resources to prepare for star parties. One of those resources is "Objects in the Heavens" by Peter Birren. He uses the same comparison diagram as you present. I thoroughly enjoy your presentations. David Fuller, "Eyes on the Sky", and David Fuller both have outstanding content and presentation skills, as do you.

Thank you for sharing that resource. I am going to check it out. I am familiar with David's content on 'Eyes on the Sky', and I think he is a great educator. I appreciate his telescope videos and how to set them up. This channel is a must-see for anyone who wants more in depth videos about telescopes.

Till which magnitude of stars you can see with unaided eye

The human limit is magnitude six. Anything with magnitude 7 or more you need magnification.
There is lot of light pollution in our area that we cannot see ursa major ☹️

That is indeed sad
Thanks you
Wait- how do you convert the light years into absolute magnitude?
A star at 10parsecs will have the same apparent and absolute magnitudes😮
Silly comment, didn't Wolf 359 play an important part in Star Trek Deep Space Nine?

I'm not sure. I am more familiar with Star Trek: The Next Generation...Captain Picard is my favorite!
I cant follow sorry
I accidentally pressed dislike but i wanted to say great video
