Musing about a video of a beautiful scene in Colorado

Richard K Collins That place call for a live 4K stream on YouTube. I found more than a thousand such 24/7 videos. Besides scenery, vistas, activity and seasons. During the day, clouds, animals, and weather. During the night stars, planets, moon, comets, satellites, more weather. With links it becomes a vivid advertisement. With links to

Comment on Hubble vs Amateur Astrophotography

Hubble vs. Amateur Astrophotographer (27 Aug 2021) at https://www.youtube.com/watch?v=0QcJaD9klDc I had to look a bit, but eventually found a description of the camera and exposure for that original image of “Pillars of Creation” at https://hubblesite.org/mission-and-telescope/mission-timeline#h4-deab74a9-f038-4a74-9313-425d13e71747 with more detail at https://hubblesite.org/contents/news-releases/1995/news-1995-44.html then some images at https://hubblesite.org/contents/media/images/1995/44/351-Image.html?news=true Like usual, Hubble media people dominate sharing on their site,

Comment on Telescope prices and sharing

What YOU Can SEE Through a $1 Billion, $32,000 and an $800 Telescope! https://www.youtube.com/watch?v=VwoII9TQd8k There are many countries with LOTS of people where $800 is more than the median annual income. And many more countries and many more people where $800 is more than monthly income. So here you are, posting a video that could

Machine vision and Industries – ZWO group on Facebook about microscopes and noise imaging

David, The lens is usually a fisheye or other lens with 1X magnification. You have to add it to a microscope meant for a human eyeball. A decent microscope is expensive and odd shaped for humans, so it does not fit in an industrial or lab or security environment. What I want is a 10x

Contact Imaging Sensors, Linear CCD arrays for gravitational and magnetic imaging

Jean, I was trying at least two pathways: 1. Build circuits to read the analog signals from these linear sensors, and put the fastest and best ADCs to read and store the data. The focus on high precision measurement of the signals as a function of reference voltage. 2. Somehow learn to talk to these

Comment on Flying over Norway video

https://www.youtube.com/watch?v=nFPECa8psWM FLYING OVER NORWAY (4K UHD) – Relaxing Music & Amazing Beautiful Nature Scenery For Stress Relief You might be able to use captions to label the locations and camera directions as the scenes change, I don’t know these places and would like to learn the names and latitude and longitude. The caption is optional,

Comment on a sunset image posted on Facebook – purpose, uses and sharing of live camera streams on the Internet

Peggy, I keep suggesting that you put in an all sky camera as a live feed to YouTube. I have been reviewing live videos like that on the Internet, and there are many of beaches, cities, mountains, forests, nature. I have found thousands of them and study them as a new Internet resource for education,

Astronomical Societies – Everyone has a right to see and study the sky, without begging or paying

Luis, I think the default should be – if I am looking at my settings – I want to change them.  I had to figure out that I first had to click on “Make Changes to Primary Member Record” (not a confirmation of changes, but getting permission to change it at all), which was after

Comment on Viki playback speeds, image controls, and search screens

I have reviewed the use of video playback speeds in various services.  YouTube uses 0.25, 0.5, 0.75, 1.0, 1.25, 1.5, 1.75, 2.0 but it is not sufficient.  I have experimented with speeds from 1/100 to 100x or faster.  Rather than a fixed set of speeds, an intelligent assistant can help. For action movies, they have

Plans for measuring the speed of gravity again, using superconducting gravimeter and related sensor networks

One linear regression is all that is needed to useg JPL Ephemeris to separate the sun moon from earth-based signals I want to repeat the SG network speed of gravity measurement I did in 2003 using all the current stations. I will also use the best of the broadband seismometers from IRIS.edu. Any absolute measurements,
