Can I use a telescope on a boat?
Yes, you can take a telescope on a cruise ship.
Why do astronomers put telescopes on top of mountains?
Most important, putting an observatory on a mountaintop means there’s less air to see through, so the “seeing” is better. On a mountaintop, there’s also less air above you to absorb light from the stars.
What is the best reason to put a visible light telescope in space instead of on the ground?
The main reason we put telescopes into space is to get around the Earth’s atmosphere so that we can get a clearer view of the planets, stars, and galaxies that we are studying.
Why are there no telescopes in stock?
Just like bicycles and workout gear, Covid has severely impacted the usual supply and demand cycle of telescopes. Many telescope factories had to shut down for 7-8 weeks as they protected their workers and implemented Covid restrictions. By April, most manufacturers had completely sold out of telescope stock.
Can you bring a telescope on a cruise?
Yes. I’ve carried small telescopes on many cruises. Finding a spot on deck where the local lights don’t prevent dark adaptation is always an issue. Given that the ships nearly always cruise at 20-25 knots all night wind is usually substantial and another thing to think of.
What is the biggest obstacle to using telescopes?
Obstacles to the Stars
- The most common obstacle is clouds.
- Similar to a shaky hand with a still camera, if your telescope moves in high wind, your images are blurred and sometimes have streaks across them.
Where is the best place to put a telescope on Earth?
For optical telescopes, most ground-based observatories are located far from major centers of population, to avoid the effects of light pollution. The ideal locations for modern observatories are sites that have dark skies, a large percentage of clear nights per year, dry air, and are at high elevations.
What are the disadvantages of telescopes?
Disadvantages:
- Very high initial cost relative to reflector.
- A certain amount of secondary spectrum (chromatic aberration) unavoidable (reflector completely free of this) The colours cannot focus at one point.
- Long focal ratios can mean that the instrument is cumbersome.
Why are space telescopes better than earth based telescopes?
Space-based telescopes like Hubble get a much clearer view of the universe than most of their ground-based counterparts. Ground-based telescopes can’t do the same, because the Earth’s atmosphere absorbs a lot of the infrared and ultraviolet light that passes through it.
Why are telescopes so expensive now?
Types of Telescopes It is recognized as a long tube that increases in length until it gets to the lens. This lens requires special crafting, which is why they are so expensive. Reflector telescopes are expensive mostly because their mirrors can be large, and thus need to be flattened out and polished.
Why are all Celestron telescopes backordered?
What is the telescope backorder situation all about? Due to COVID shipping and manufacturing delays, AND the increase in astronomy product demand that has occurred at the same time, most telescopes and many accessories are on backorder — some telescopes are on extended backorder.
Why do we need telescopes in space?
And lastly, to state the obvious, it’s pretty expensive. So why do we even do it? The main reason we put telescopes into space is to get around the Earth’s atmosphere so that we can get a clearer view of the planets, stars, and galaxies that we are studying.
Does a telescope need to be in a valley?
The telescope is not required to be in a valley. Though if a radio telescope is surrounded by hills, it will reduce artificial radio noise. Radio telescopes such as Arecibo are built in depressions that are near the shape of the main dish. This makes the supporting structure cheaper to build.
How long has the Hubble telescope been in space?
The Hubble Space Telescope was launched into Earth’s orbit in 1990 over 25 years ago. The Spitzer Space Telescope, Hubble’s infrared sister, just celebrated its 15th anniversary in space.
How many telescopes are there in space?
How many telescopes are there in space? There are currently around 25 active telescopes. Most of them are on Earth’s orbit with only a few exceptions like the Spitzer Space Telescope which was sent to orbit around the Sun in 2003. Most space telescopes are also built for specialized frequencies like Gamma, X-ray or Infrared.
