Love it !❤
has anyone made a reanalysis of the egyptian chronology using the sothic calendar system and searching for anchor dates that can be used to synchronize egyptian regnal years
A very nice tribute, and it was great seeing so many of the photos that I took of Blake.
Hi Peter. I hope you don't mind that I didn't credit the photos. There were too many from various sources to keep track of. I am glad you were able to take these RASC TC photos. They stand out. Andrew
@@RASCToronto No worries, Andrew. You and the crew did an awesome job as always! No credit was necessary. I'm just somewhat disappointed that I never knew about this event. I would have liked to attend and pay my respects. Thank you as always for what you do, and take care.
@@petervisima4798 Its too bad you didn't know about the event beforehand. This is one of the reasons why the organizers wanted us to stream/record the event so people who couldn't or didn't make it could see it. I am glad that you at least got to see the recording.
It’s a birth calendar. One of two possibilities. The second is it’s a doorway endows by God to keep certain beings cast out!
exellent! This présentation kick out à big part of my stress. I'm actualy grinding my first miroir. it Will be ~201mm and i hope around f/d ~~7.63~~ . And yes Normand is a realy Nice persson. the fact is that i'm actualy work on his first turning table....a gift !😊
Thank you ❤😊
Application not available in Canada...
What is the link to download the application for iOS
It looks like the app has been removed on Android so I am guessing that would be the same on iOS. The website is still working I have added the URL in the above description. I have tried to contact the developer for more information and so far no luck. I will keep you posted if I hear anything.
I love watching videos where someone is so passionate about what they love. Thank you for sharing with us.
Amazing project, Thank you for the video. Would the fast focus possibly lead to the degrade in planetary resolution? I'm no stretch an expert with just a few semesters of astronomy in college but would like to pass the gift of science to my young children. My Prof told me the best telescope is the one you can use and I would like to incorporate this design with something that is more portable or collapsible.
Haha first post ,, look forward to build another observatory soon ,, nice build you made 👍 bett your warm inside ,,
Is it possible to have more details on her amazing work?
Very good! Thank's for sharing!!
welcome to the darkness, where its slow and messy..
I seen 2 eclipses and I have video❤
I'm more interested in cost savings as are many rational amateur astronomers.
I have heard that you should not look at the sun even with glasses until near totality. Is this true?
Fascinating!
Amazing presentation, this research is so interesting!
Learnt so much ! Great presentation ❤
Very informative, excellent presentation!
Love this presentation, very well done
Hours/Horus Horizon/Horus Rising
I just purchased a pair of helios stellar2 16 x 80 and the difference from the 10 x 50 pair i have is incredible. Nitrogen filled, IPX7 rated, quality multi coated optics, bak4 , extremely well made. looking at terrestrial or astronomical targets is breathtaking. Don't hesitate to get some big binoculars and choose wisely you don’t need to spend silly amounts in order to get a good pair. Im 55 so figured the 5 mm exit pupil was sufficient for my age /pupil size.
Blake, man I miss you so much. You will always be in the Hall Of Fame of Teachers. ❤🔭🌌🐜
I saw the total solar eclipse in Santee S Carolina July 26, 2017. It was amazing. A few minutes before totality, the day started looking like dusk. Birds started chirping. Then it happened quick. Some stars came out (I believe they were actually planets). It was like night but not pitch black. And most amazing was the sun’s corona(it looked angry/scary; not a uniform glow near the eclipse but like streams pointed out radially from the sun stronger in some directions than others, and about the angular length of the Sun diameter). It was ominous to realize that corona was always there my whole life, just normally hidden from view. It reminded me of a subconscious awareness that always was there but normally hidden from the conscious awareness. The other surprising thing was seeing the planets. I also looked to the distant clouds on the horizon for any signs of the edge of totality but could not see it. The sunlight returned extremely bright faster than you could blink (I should have stopped looking at after a couple minutes when the total eclipse was gonna be ending soon). Even just 0.01% of the sun’s disk is dangerously too bright to look at. I can see why a total solar eclipse had a huge emotional impact on the people who experienced it
Thank you for sharing with the UA-cam community, an excellent presentation.
9th grade? Wow, there is hope for the future! 🙂
What do you think about the celestron 20x80 ED pro and the 25 x100s? I am a beginner, novice, but i wanna buy something half way decent to view rhe stars and i would like to get a cell phone mount for use on one of the eye oueces for added power . What say you? Thanks for this video!!
What did you end up getting? I'm in the same boat now.
The water drops associated with each month for a night’s duration should reveal which time of year on our calendar was each of the 12 Egyptian months.
Yeager was Armstrong's worst test pilot. Woh! Now I'm roped in. Gonna have to read that book. I did read Yeager's autobiography, in 1986, and I do recall he had some criticisms of Armstrong.
I'm focused right now on the Yeager character lynching going on as part of the Ed Dwight legend, are you interested in collaborating on research?
@@JamesOberg Thanks for the interest, but my interest in apace history is as a casual observer. I have no dog in that particular fight. Not even sure if you mean lynching OF Yeager or BY Yeager! BTW I think of myself as mostly a techie, but increasingly the management and human relations sides of the Space Program are what I find fascinating. Now, if you want to know about energy, climate, and the parts of futurism connected to those things, I can deluge you with all kinds of stuff. That's my real bailiwick, since about 2002. Actually, I don't even know who Ed Dwight is, but in a couple of minutes, I will. EDIT: Oh, yeah. I think I did hear something, but the memory faded. Ed's path was a slow and twisting path. The kind of long, strange trip that I admire, but wouldn't recommend to follow. You can still ascend higher if you rise faster, if you are able to.
@@ronaldgarrison8478 = Your comments are sharply focused and will send me off on promising new tangents, so please don't be a stranger.
@@JamesOberg Thanks again. I found a video of you and bookmarked it, editing the title to remind me to keep an eye on it.
I wonder if there will be any juicy stories about the Artemis crews. There certainly were plenty about the Sixties astronauts, although they took a long time to come out.
Boy I love these stories. All the videos where people document how they crated something incredible often in their spare time are so inspiring.
What's coma like at f2.6?
Some astronomers looked at the reflection of stars in pools of water in a palace or buildings. They did not have to crane their necks to look up at the sky for hours on end.
Superbe idée ce toit qui s'ouvre en deux , j'adore le principe Bon ciel à vous et merci pour le partage 🗼🇫🇷
This is an excellent book! I use it as my observation diary.
Thanks for mentioning our products. We are happy to answer any questions folks may have about the silvering process. This is a great video!
What ever happened to the David Dunlop observatory?
Still going strong. Its owned by the City of Richmond Hill with operations run by RASC Toronto and DDOD group ua-cam.com/video/Q9yVgqFRtdI/v-deo.htmlsi=63dWXzKZj6P45_BE
Not all people in the u s are violent gun owners. Don’t judge us, Swiss land has just as many as the u s.
The Cambridge Double Star Atlas has great double page star charts and 2500+ multiple star system up to 7.75 magnitude primary and up to 13 magnitude secondaries. 80% of the stars can be seen with a 4" scope and I use an apochromatic 102mm/4" up to 450 magnification. My 6" reflector has custom mirrors on it with the primary 1/12th wave and a Strehl of .98 ratio , but I will use it with my AZ Pro that holds two scopes for outreach, but otherwise it gets used for AP. Just easier to use the smaller scope, but if I have a smaller target I'll use the 6" to 400x, but I need my 2x TeleVue Barlow. I often use orthoscopic eyepieces down to a Baader 6mm Ortho.
How do I find out what’s happening this month then cause I was counting on the only thing I heard of was the meteor shower on the fourth but I don’t think I’m gonna see it and it’s starting dawn on me that there’s something going on in the sky every night
👍
This was super super interesting! I just bought my first pair of 25x70 Celestron's but now I am thinking of returning those and keeping the 20x80's. But this was super helpful as I got lots of ideas and a big does of inspiration on what I can do and what I can expect to do with my big binos ❤
Bro can u suggest me which should I opt for 25×70 or 20×80 for casual night astronomy?
how did he find out the aphelion and perihelion of each planet? Kepler claims he was using Tycho Brahe's data. But they cannot have made such accurate observations. I am looking at the book published by Great Minds Series, Epitome of Copernican Astronomy and Harmonies of the World page 186, the table, column 2. Thanks,
Fascinating local history investigation story!
Very cool telescope, thanks for the talk
