it's surprising how useful this channel can be, even when videos are quite old they're more relevant than more recent ones
Brilliant video. I'm a total astronomy rookie, but it explained a great deal about the night sky.
By far the best presentation on planispheres. Well done. Thanks
Ok uujjjyjyj ikuo
Great tutorial. I learned a lot. Actually I have learned most of what I know from your videos. Please don't stop.
That was brilliant, very informative, will be buying one of these immediately.
Very simple, clear, concise explanations. The man is brilliant in all his videos.
Thank you very much. It was very informative!
Saved for rewatching. Thank you!
Hello, I've watched a few of your videos and I have to say how well and informative they are , well produced and well presented throughout. Well done. ! Enjoyed them very much. Kind regards.
This is the most useful astronomy video I have watched so far. Thank you!!!
Very well done. You explained some fine points of planisphere use even experts might not realize. I didn’t! Thanks!
Wow that was a super explanation, thanks! Loved the history at the start too. Keep it up.
Thanks for this video. Helped me out bunches.
Beautifully presented and informative, a pleasure to watch, thank you.
Mind blowing, informative. Never knew what I had been missing out on. Many thanks!!!
writing an essay on planispheres and this video helped immensely thank you
This video was very helpful. Thank you for making it.
This was so helpful I just bought some binoculars to start finding my way around the stars and was having trouble with my planesphere. Really a huge help!
VERY WELL PRESENTED THANKYOU VERY MUCH - I'VE FOUND THE BLUE CROSS AT LAST THANKS TO YOU !!
Beautiful presentation ; thank you.
Just ordered my phillips planishere yesterday, so should arrive shortly and would just like to say thanks very much for giving me a heads up on how to use it. I found this video very educational and easy to understand without ever actually having a planishere in my hands!
This is a great channel, easy to follow and covers every subject including rockets ie V2.
An exceptional tutorial, thank you.
Awesome presentation, thank you.
I bought a glow in the dark planisphere yesterday and i am very pleased with it , it's nice to have two planispheres' ! One for upstairs and one for downstairs !
My girlfriend has just bought me a glow in the dark planisphere for christmas. This video has made the instructions much easier to get my head around. I will definately be following your channel :-)
Thanks, great explanation. Well described for the beginner, especially with large planisphere. Excellent tutor! Keep up the good work.
thanks Robert, this was an excellent tutorial!
you are a great man thank you for your education for all of us to make and take use of .
Very nice explanation for beginners such as myself! Many thanks for sharing.
Fantastic explanation! Thank you!
...thank you very much, excellent video, very nice work...
I learned something wonderful today. Thanks :-)
Awesome demonstration, it makes alot of sense using geocentric cosmology model
Thanks for a great video. I live in the U.S. and use two planispheres. One is a 42 degrees north latitude Philip's, and the other is a slightly larger 40 degrees north latitude Miller. Both are very well made from weather and dew resistant plastic. I highly recommend either of these for most of the U.S. They are probably well designed for much of Britain and Europe as well. Happy stargazing!
Absolutely brilliant film thank you
Amazing masterclass ... Thankyou... 🙏
you make it easy to understand, great job. only wish astronomy in general was as simple, for a simple person like me. some of it is mind blowing.
Nice video. Thank you!
Many thanks for the information about the sun sent by e mail . I am really enjoying the planets this year and get my directions fron earthsky . The Philips Planisphere is wonderful , i now have a map of the sky , i have missed so much over the last 60 years !! If only more people knew what is up there and how they can view the night sky . Thankyou once again .
This was wonderful
Great explanation for a new astronomer. Thank You!
I got mine today. Your video has really helped. Cheers.
Another superb lesson in how to present a video.
Also you could use it as a star clock. (Not sure I'll get this right because it's day now and I can't test it.) If it has an arm on it, line it up with the two stars of Ursa Major and the pole star, or else put your finger at around 11hours9minutes right ascension. Look at the pole star through the middle and line it up with the great clock hand in the sky, so now your planisphere is correctly aligned with the heavens. Then lower it down and turn the centre disc so south points directly at the pole star. The date should now tell you the time (or vice versa), and also your planisphere will be ready for use.
He is fantastic.
Superb tutorial.
Hi, thanks for watching - there's no difference. Philip's is a British company but they have an arrangement with Firefly who make them under licence in the USA. Kind regards A&NTV
Great job man !
Very good. a lot of learning points. well delivered
Thanks
Nice guide. Thanks for posting.
Fantastic and very informative.
thank you
Excellent.
I need that 'Land of the Giants' version! Great stuff.
Absofreakin' beautiful! Long but beautiful!
Thank you
thanks i just bought a telescope and wanted to start this and i have this planispshere and your video helped allot
Many thanks
I have one somewhere that was made in Germany before WWII (I don't remember the year). Since it is latitude dependent, it was useless in the southern hemisphere where do I live. Nowadays with computer software like Stellarium and devices such as smartphones and tablets paired with GPS and astronomy apps for these devices, the planisphere has become a crude primitive tool, however it is still useful to help understand how the night sky changes according the months.
Well Done. Thank you.
excellent thank you very helpfull, ive seen your other vids all excellent.
Excellent expectations
I am retired merchant marine and, what to exspore the night skies again. Great info thanks, from mexico
Great video I have been trying to remember the location of planets and constellations in my head but finding it fun but overwhelming at times. After watching your great video i am definitely going to invest in a planetsphere now all I have to do now is decide which one lol. I do like the look of the Phillips. Thank you very much your knowledge is much appreciated :+ )
Hi, thanks for watching. You're not the first to want to buy it! Its was actually made for us and is one of a kind. Kind regards A&NTV
Ah, I was just shopping for one, and had no luck. Decided to see if it'd been asked in the comments, and here I see the sad news.
Class
FRAS: you are my FRIEND.
Great video. Is there a different planisphere for use in the Southern Hemisphere
Great video, I'm trying to find a huge Planishpere like the one you have here: Do you know where I might find one!!?
Great video, I've owned a few planispheres and never new about the sunrise sunset thing or how to use the planet finder on the back. You might mention that north and south are reversed so that they are right when it is held overhead.
Hi - No it won't be useful at equatorial latitudes. I have seen an equatorial Planisphere on sale in the UK but I’m struggling to remember where. It may have been Armagh Planetarium’s stand at AstroFest a few years back - if I recall correctly it was in Spanish? It’s not a common item and I can’t ever remember being offered one by our suppliers. Sorry I can’t be more helpful. KR RJD
Could you make an overlay of the planisphere (stars/constellations map) over the Gleason map and see if it corresponds? A landmark to align could be Orion's belt over Giza. Other stars could correspond with islands and important structures on earth. @Astronomy and Nature TV
Can you find moonrise and moonset for any given date using the planisphere?
I've owned one for a few days and I never saw the overhead cross with my general purpose Spex on. I'm thinking that could be glow in the dark also or even the colour Red. Luckily at my position Polaris is easy to pick out and from there it all unfolds. Thanks for the post.
Hi and thanks for your message. Lots of folks use the Planisphere perfectly successfully without ever seeing the blue cross. My oldest Philip's Planisphere doesn't actually have the cross. But when you learn to 'see' the cross, it ties the start position for your observing to the map more effectively than just Polaris and the nearest horizon - and is a very useful addition to get your bearings. It works well in urban locations too where you may not be able to see Polaris - or any real horizons for that matter - but you will always be able to see the zenith. KR RJD A&NTV
where can i get one like the glow in the dark one you showed
thanks
HI i live in South Carolina. I would like a planisphere for the south night sky. could the phillips one do that for me? and where can i get one for class?
Thanks
Hey, I noticed you don't have any replies after a long time. So, Basically I believe there's a southern hemisphere planisphere, but I don't believe philips have any.
What I would like to know is where can I find the Star and Satellite Path finder put out by the Anchor Optical Company.. I have seen pictures of it but there was no way of how to obtain one.
Awesome giant wall-planisphere. Where can I get one like that?
my planisphere does'nt have a little blue cross, does it make any difference
👌💫
What time zone is the time reported at ? I would assume all of them are made to use Greenwich. But the instructions to mine made for 42 latitude of North America don't specify that and suggest it is in "my local time" by mentioning only daylight saving time. But I could be located at any of 4 or 5 timezones in North America.
In terms of circumpolar objects, you should have noted that it depends on latitude
Hello,
I live in Dhaka, Bangladesh and it is centered on 23.8 deg North. Is it possible to obtain a suitable version of the Planisphere for me to use?
Regards,
there are other non-phillips versions however
Hi, the video is great. I have a question:
¿What is the difference between the Philip's Planisphere and the Firefly Planisphere?
0:08
what is this called and can it be bought online?
your planisphere goes upto 2020 how would you find a planet on the Ecliptic line with no degrees to go from on the back of the card ? thanks for the film it was good
Can the latitude 51.5N planisphere be used in Switzerland (47.3769° N, 8.5417° E)?
a good planisphere should be within about 5 degrees of your latitude so yeah looks fine
I live in Australia, I know the earth rotates throughout a year but are there things on certain continents that cannot ever be seen or can everything be seen at different times of the year?
Yes. If you are in Australia, it is impossible for you to see the stars close to the North Pole, that folks in Northern latitudes can regardless of the time of the year at which you look. On the other hand, I have never seen the southern cross from the US because it is not possible.
my planisphere does'nt have a little blue cross does this make ay difference
not getting why we can use this in different locations or us or britian, do you need to buy different planisphere for where you are or just one for whereever in northen part of world, thanks for video
So im in Peoria il and im seeing the same stars at 2300 at night that someone in Rome is seeing at their 2300 at night? Because were roughly at the same latitude? Just wondering how different sides of the earth arent seeing stars at different positions
Where can I get one?
The Miller Planisphere is based upon the Alexander Gleason Azimuthal Equidistant Map which is based upon a flat, non rotating earth.
Nope. The Miller Planisphere is just based on older versions. The shape of the Earth is irrelevent to the operation of a Planisphere. And Gleanson was just having a laugh - his map is a depiction of the Earth as a globe in a north-polar azimuthal equidistant projection (he declares this fact in his own words in his 1893 patent claim). KR RJD A&NTV
Why there is no 29 feb in this chart??
What version do I need for Chicago view
+Amber Flores Hi there, the version we are demonstrating in the video is mainly for the UK and Europe and is centered on the latitude of London at 51.5 deg North. The Chicago area is centered on 41 deg North - the one in the vid is good for Northern USA in principle (max 10 deg N or S from 51.5) but, you never know, you may wish to stray South of the Windy City one day! There is a publishing company in the USA called Firefly that reprints Philips (UK company) titles under a licence agreement. And I am fairly sure they still produce a Planisphere identical to the one in the vid only centred on 42 degrees (I think they do a 32 deg one as well) - making it ideal for you and will cover the rest of the USA too should decide to roam. I hope this helps. KR RJD ANTV
+Astronomy and Nature TV thank you so much I'm just getting into astronomy and just learning thank you for your you tube videos I will Google and see if I can find that one 😄
I only went a bought the 2001 versions which only goes up to 2009. Does this render it useless and outdated?
Ahh ok thanks :)
where i can buy it
www.amazon.co.uk/gp/product/1849071888/ref=ox_sc_act_title_4?smid=A3P5ROKL5A1OLE&psc=1
I bought the recommended "The Night Sky" planisphere and even after reading this tutorial and watching the video (and several others) it makes no sense: 1)holding the thing flat in front instead of overhead means if you orient north and south correctly east and west are reversed; if you set east and west correctly north and south are wrong. Nothing can be found where it should be if it's used that way (and FWIW holding it overhead seems illogical since - at least in my case - it can't be held that way comfortably long enough to even read a couple of words).
2) I'm also at low altitude in the city so there are a very limited number of stars to use for location cues, and - I have tried every type of backing , lighting, magnification - and there is NO "blue cross" or other position indicator. So with no way to be sure "overhead" is actually overhead (or, I guess, directly in front?) and with half the compass indicators inherently wrong how ARE people actually using these?
This tutorial does a great job of showing what's ON a planisphere, how to set the time and so on - but like others I watched to try to figure the thing out it's filmed indoors, pointing out features - but not showing one in actual use! amI right in assuming that the only way one can be used outdoors is to hold it overhead"? If so it's a waste of money unless you have strong neck muscles and a third hand to hold a red flashlight - and a 4th to hold the planisphere if you want to use binoculars. They just seem more "cute" than useful.
You can make these so that they work either way. I am not sure what is the most common.
Sigh .... my kingdom for a 16" sct ! Is that what that was in the observatory ?!
