Small bit of constructive criticism. There are several clips where you seem to be editing multiple audio recordings together, but there's little to no gap between the last word in the first audio clip, and the first word in the second audio clip. I would suggest adding anywhere from 1/2 to 1 second of pause between these clips. It makes the audio flow better, and easier to understand.4:58 - 5:01 is one such example
I really appreciate this feedback! I'll keep this in mind for next time. My video editing software can automatically delete the silent parts, and apparently I need to double check when it's deleting too much. Thank you!
Excellent video!! I saw some of the other recent f ratio myth videos and had a number of items that bugged me about them. Very glad you made this video!!
I think the key issue that most people miss (including me), is that while constant f ratio keeps the photons/pixel constant, it DOESN'T hold the pixels/arc-second constant. That varies linearly with aperture (for constant f-ratio and pixel size). Further confusing things, a larger aperture (all things being equal) will usually be capable of a larger 'flat' FOV in mm at prime focus, yes? What does this say about the cost of the sensor needed to fully utilize larger aperture? Larger sensors are expensive.
Yes! That's a very concise explanation of the problem and how to understand things. I feel that everything gets more expensive as you increase aperture 😅
I want to thank you for validating (and using the same equations) my point to a fellow astronomer almost a year ago. It got pretty heated and devolved into comparing the HST with an 80mm telescope 😂. My take away from research was that “it’s complicated” and any single metric is not really a valid tool across a broad spectrum of devices and configurations. It’s nice to see someone else put pen to paper.
Great explanation! I already understood the concepts, I hope it informs others as well. Maybe we should adopt a different metric for image capture performance? How about aperture/pixel size (or aperture area/pixel area for more manageable numbers?
That is an interesting idea! It'd take some thought to get a good metric that's as easy to understand as f-ratio. But maybe, we can figure something out.
@@deepskydetail that would be sweet! i’m in the same boat, im pretty experienced and versed on the DSO aspect. but im trying to transition to planetary work as i’ve moved into bortle 9. i feel like im relearning everything again and there’s not much resources online.
I love how Doctor Detail is supposed to be a bad guy and nemesis of deep sky detail and yet they are also all chill and you get the feeling they are friends behind the scenes. Do I spend time analyzing the lore behind the characters on Deep Sky Detail RUclips channel? Yes, yes I do.
Thanks! I'm glad you enjoy the lore. I enjoy it too! I agree. I think deep down they all respect each other on and off the set even if they're all spying on each other all the time.😂

The 'Tri' is size of scope , a suitable mount , a suitable camera.
The 'Force' is what damages your bank account!
That also makes sense. Especially about the bank account 😅
You put a lot of time and effort into these videos. It is appreciated.
Thank you! I appreciate someone appreciating the work put in :)
Also, saw your video of the pier yesterday! It was great!
@@deepskydetail Thanks

Thank you!! It's so easy to get confused about signal. I'm glad you enjoyed it :)
Great video Mark! Love your deep dives on these subjects!
Thanks, Rich!! :)
I like the video. Your deep dives are amazing. Makes me wonder if......... ahhh, never mind. Great video!
Thank you :) And you are correct, I am secretly a master of the universe working out of Castle Grayskull!

Fantastic video as usual!
Thank you!
Is aperture king? Yes. /end video
06:50 😉
The larger your diameter the smaller your stars are for a given f ratio. This because resolving power is aperture dependent.
Yes, good point!
do a planetary astrophotography one. next
I can try! I do planetary, but I'm not as well experienced with it as DSO stuff. So, I'll have to do some research ;)
