I would like to know if you can make any astronomical sightings during the day.
Transcript to follow.
Sunspots are much better to visualize during the day than during the night!!! Of course, look up on the internet about how to make an appropriate apparatus to visualize the sun.
I wonder if a filter can remove the "atmospheric" blue from the field of vision to allow us to see the (bright) stars during the day? Lmnre, Sat, 13th Jul 2013
If conditions are right, the moon is sometimes visible in the daytime sky and on one occasion I saw daytime Venus, it was a total accident, happened to be looking at a jet trail. Never been able to spot it again. Mostly we do sun spots using a telescope and projection screen. We were able to see Venus transit the Sun with this method. Next Mercury transit is 2016 May 9 http://en.wikipedia.org/wiki/Transit_of_Mercury.
Here's a picture of Venus crossing in front of the Sun, telescope image projected on screen, large dark spot is Venus, the other dark marks are sunspots, a pretty active day on the Sun!
Isn't it true that in certain circumstances Venus can be seen in the sky without a telescope? Recall that this is what Elenor's father said to her in the movie Contact. Pmb, Sat, 13th Jul 2013
Yesterday afternoon I showed visitors craters on the crescent moon through a telescope, even though the Sun was still shining.
"Edit: Uh oh. Snopes says they must have been pulling your leg."
The latest generation of amateur telescopes have a computer and sensors from a smartphone. This seems to add about $500-$1000 to the telescope price.
I have seen three real interesting day time astronomical events in my life time, the total eclipse of 1999 that I waited for for 65 years and the two recent transits of Venus.
The question did not say see things with the naked eye, although I have a possible exception to this in a moment.
I believe that radio telescopes can be used during the day.
Scattering of light from particles in the atmosphere increases as the 4th power of frequency - which is why the sky is blue in the daytime.
Here's is a fairly unusual daytime event in just a couple days, a hybrid or annular-total eclipse:
I was thinking (even though it usually gets me in trouble), if we had a supersonic plane, 1000mph/1675kph would be nice, that could sustain this speed for several hours, you could follow the path of the eclipse keeping the moon directly in front of the sun and make a movie of it changing from annular to total. Are there any jets in service that can fly this fast? The SR-71 and Concord could do it but I believe both are retired. Perhaps Sir Richard Branson has such a device. distimpson, Sat, 2nd Nov 2013
The sky is least bright directly overhead as you're looking through less atmosphere, so the idea of seeing stars during the day up a chimney or from the bottom of a well doesn't sound impossible. The Sky at Night Magazine recently gave instructions about how to see a star in daylight with a telescope, something that isn't normally easy to do, but when the moon is near it you can use that as a guide to the exact position of the star, at which point you can make it out.
