First off, I know that a 55 mm camera or CCD camera would be the obvious solution to taking picture of the night sky. But I have this Olympus c-750 digital camera with 10x optical zoom, a wide angle lense, a circular polarizing filter, and a skylight filter, and wanted to know how I could make it useful at night. How can I make the camera more sensitive to light? I wish there was a way to somehow open the shutter as you would for a normal camera and let it take long exposed shots, but I -don’t think- this is possible. How could I atleast then slow the shutter speed? Is there anything else that I should know about, any other variables that would effect my shots? Any help would be very much appreciated. Thanks!
That camera will do exposures as long as 16 seconds, which is not long by the standards of astrophotography, but pretty long by any other standards. You probably need to use manual mode to access that shutter speed. See page 24 of your manual.
I have a digital camera, how can I make the best out of it with astrophotography?
Where is Earth’s galaxy on the Big Bang Spectrum? Are there other galaxies that are behind us?
In other words, some galaxies are expanding away from us. Are there any that are compressed behind us?
Everything is expanding away from everything else, there are no galaxies behind us or in front of us. Some galaxies are coming towards us but only because they’re near enough that their velocities are greater than the expansion velocity caused by expansion rate of the Universe.
Have a look at the rubber sheet explanation for the expansion to see what I mean.
Is it possible to capture UFO images by Hubble telescope?
Can hubble telescope capture UFO images?
They already have. Unfortunately, NASA blocks out those pixels in the images. It’s the same with the pictures they have taken of Nibiru from the IRAS satellite….certain information cannot be released to the public at the demand of the government.
There were a few pictures that someone got their hands on before NASA had the chance to obscure them showing HAARP firing some sort of energy beam at an object that took off at a phenominal rate of speed before the energy beam or whatever it was hit it. It’s rather easy to find and is an amazing picture. There’s also NASA pictures leaked that show a cluster of "curious" little objects swarming a tether from the shuttle….
I have a Meade telescope with autostar, and some other kind of plug in receptacle I can’t figure any of it out
I can’t seem to comprehend the instruction book or the autostar as to how to see constelations or planets and what the other plug in is for. On the telescope. it resembles a phone receptical plug. I’m assuming that it plugs into my computer, as I also have some software with it. Where can I go for help? It came with 2 lenses. I’ve had this for 2 years and desparatly want to learn how to use it.
Take it to the shop it came from and ask them to help you. This is not a cop-out; it’s the best advice anyone can give you in this forum.
How astronomers can predict planetary alignment?
How astronomers can predict planetary alignment?
ok so this is the main question. i’m not very good with science but when it comes to star gazing im good with that. this one question popped into my head and i wanted to know if anyone could help me out.
There is a variety of software programs available which will accurately predict the positions of the planets for thousands of years into the future and past. They can be set to flag alignments, so that all you have to do is search through time, and all the alignments will appear. The software which I use myself is Starry Night Pro.
How does Hubble’s expansion jibe with the speed of light?
According to Hubble, the more distant galaxies are moving faster than those close to us. But, because light takes time to arrive on Earth, we’re seeing how galaxies *used* to be, the more distant in space the further back in time. I guess I’m asking how couldn’t it be argued that cosmic expansion is slowing down, since light from "more recent" galaxies shows less red shift than "older" galaxies? Sorry, this is just a weird question that’s been hanging around in the back of my brain for a while. Comments?
Some distant galaxies appear to be accelerating away from us, not just moving at a uniform speed.
And the most distant galaxies are probably expanding away from us at more than the speed of light. This does not violate the special theory since no information is being transferred (see reference).
Should I use Watercolors or Oil paint for "Starry Night"?
I would love to try to paint Starry Night, and I have a vast variety of colors in watercolor (about 20 paints), and about 8 oil paints, which would be better?
use oil, part of the fun of the starry night painting is it’s texture which you can’t get with watercolor…
why isn’t space outside as bright as earth? Isn’t the sun the source of light for the solarsystem?
all the photos and pictures I have seen of the space are dark
If you shine a flashlight in a dark room, the beam of light must hit an object in order for you to see it. If there is nothing to obstruct the light, then you will still see a dark room despited the flashlight. The same is with the sun, the planets are visible because they obstruct the light and reflect it back to our eyes. Everything else is black because there is nothing there.
AstronomyBuff #2: Stellarium and Planetary Alignment 6/30/07
There is a cool planetary alignment this Saturday, June 30th. I wanted to play with Stellarium and my new screen grabber software to produce a ‘planetarium-style’ presentation.
