Question: -- I will be observing at home. Where should I set up my telescope ?

Telescopes FAQ - How to Setup & Use a Telescope
Answer: -- Not in your living room. Observing through the window of a house will drastically reduce the performance of your telescope. Go outside. If possible, set your telescope up away from buildings, parking lots, patios or other objects -wooden or cement - that absorb heat by day. These objects radiate heat back into the sky at night and will create air currents that degrade the images in your telescope .

Besides my telescope, what else do I need for observing?

Howstuffworks "How Telescopes Work"
First of all, dress warmly when you go out at night! When the sun goes down, temperatures fall and moisture condenses. You would be surprised how cold you can feel even on a hot, summer night. I have been observing on summer nights in North Carolina and needed a sweater and jacket even when the outside temperature is 60 degrees Fahrenheit. If you are not comfortable, then you will not enjoy observing.

Question: -- Can I observe right away after my telescope is set up?

Telescopes FAQ - How to Setup & Use a Telescope
For you, it will take at least a half-hour of uninterrupted darkness for the pupils of your eyes to open to their fullest and be at their most sensitive to faint objects in the night sky. Furthermore, sudden exposure to bright light will quickly cause you to loose your dark adaptation. To read a star map or see the controls on your telescope , cover your flashlight lens with several layers of red plastic or paint it with several layers of red nail polish.

Can I build a radio telescope at home?

Frequently Asked Questions About Radio Astronomy
Many electronic experimenters have built their own radio telescopes. In fact, the world's second radio telescope was built by an amateur radio operator, Grote Reber, in 1937. Amateurs use a variety of equipment, sometimes modified satellite receivers and dishes, to build their radio telescopes. For more detailed information about amateur radio telescopes, contact the Society of Amateur Radio Astronomers.

Question: -- What can I expect to see in my new telescope ?

Telescopes FAQ - How to Setup & Use a Telescope
Answer: -- You will be able to see many of the same things you see in magazines and books, but the images produced in your telescope will smaller and less spectacular. The images in magazines and books are produced by large observatory telescopes that take long exposure photographs with special cameras. It simply isn't realistic to expect a small amateur telescope to produce visual images of the same quality .

Question: -- Which eyepiece should I use to begin observing?

Telescopes FAQ - How to Setup & Use a Telescope
Answer: -- ALWAYS start observing with the lowest magnification eyepiece available until you become skilled in the use of your telescope. This will be the eyepiece marked with the BIG number (longer focal length ), not one of the smaller numbers. Again, the number you see on the eyepiece is the focal length, not the magnification.

Question: -- Where is the best place to observe with my new telescope ?

Telescopes FAQ - How to Setup & Use a Telescope
Answer: -- The best locations for astronomy will be rural areas far from large cities that pollute the night sky with outdoor lighting. This "light pollution" washes out many of the faint objects of interest to an astronomer, as does the light from the moon. A small telescope when used under a dark, moonless sky can match the performance of a larger telescope used under a light polluted sky or a moonlit sky. (Most astronomers do not hold the moon in high regard for this reason.)

Why don't you see color when observing sky objects in a telescope?

faq.html
Many times we see astro photographs that reveal a variety of deep colors in most deep sky objects, yet when we look at them through a telescope they usually show a faint gray or bluish haze. This has to do with the way our eyes sense light. The retina contains sensors called rods and cones. Rods detect black and white, and are seven times more sensitive than the cones, which detect color.

How big should my telescope be?

Howstuffworks "How Telescopes Work"
The telescope's ability to collect light is directly related to the size or diameter (aperture) of the objective lens or primary mirror. Generally, the bigger the lens or mirror, the more light the telescope collects and brings to focus, and the brighter the final image. Aperture is probably the most important consideration when buying a telescope, but it is not the only consideration. You want to buy as much aperture as you can reasonably afford; however, avoid "aperture fever.

How powerful should my telescope be?

Howstuffworks "How Telescopes Work"
This consideration is perhaps the most misleading to novice telescope buyers. Often, manufacturers of "cheap, department store" telescopes will display "200x power or more" on the boxes of their products. The magnification or power has little to do with the optical performance of the telescope, and is not a primary consideration.

I have my own telescope, can I set up during the Star Party?

Frequently Asked Questions | McDonald Observatory
Yes, by all means, feel free to give us a hand. As long as you're willing to let others look through your telescope and answer the questions they may have about it, you're more than welcome to set up with us. If you'd rather not have people around your expensive telescope, you're welcome to do your observing after the public Star Party. The Observatory is NOT a campground, however, so if you're here, you should be observing.

What do we learn from observing afterglows?

Gamma-ray Burst FAQ
Observations of the afterglows all across the spectrum tell us many things about gamma ray bursts. First, observations of the first afterglow in 1997 confirmed that gamma ray bursts occur in very distant galaxies (see question 2). Second, from observations of the afterglow we can determine how much energy was released in the gamma ray burst. Third, we can determine how much material was present in the vicinity of the gamma ray burst.

Question: Is it possible to see the astronomical new moon (invisible moon) using telescope?

FREQUENTLY ASKED QUESTIONS ON MOON-SIGHTING
Answer: The astronomical new moon happens when the moon comes between earth and sun, and that new moon cannot be seen by the most sophisticated telescopes. One Saudi Prince went up in a rocket to try to see this new moon from the space in the high skies and came back confirming that it was not visible. That's why it is called invisible moon, becuase its lighted portion is towards the sun and dark portion is towards the earth.

Q 13. What is the significance of observing noble silence?

Questions on Anapana
Ans. It has a great significance. All our efforts are towards quietening the mind. We have already experienced how talkative the mind is. Even though we want the mind to observe the breath, it hardly observes a couple of breaths before it indulges in its old habit of thinking and talking endlessly with itself. We want it to quieten down and become involved in the task of observing the breath, but despite all our efforts, it does not calm down.

Question: How are the turns made, and is there a set turn radius?

faq
Answer: The turns may not be initiated until the turn judge raises his flag (for the two 180 degree turns), but may then proceed to be any turn radius and rate the aircraft is capable of. The 360 degree turn can be initiated anytime the aircraft is on the "downwind" leg and also may be any turn radius and rate the aircraft is capable of.

What is a "binocular telescope"?

Astronomy Binoculars - Frequently Asked Questions
A binocular telescope could be loosely defined as a large-aperture binocular that accepts standard 1.25" or 2.0" telescope eyepieces, must be mounted like a telescope, and can attain similar levels of light-gathering power and magnification as a small telescope. Garrett Optical's Signature GT80-45 and GT100-45 binocular telescopes are two such instruments.

Telescopes FAQ - How to Setup & Use a Telescope
Answer: -- NO! These screws are used to align the primary mirror. If you tighten these, your reflector telescope will no longer be in alignment and images will suffer. Worse yet, the mirror may come loose in the cell and you will need to reassemble the telescope! Answer: -- After your telescope is assembled, you will need to adjust the finder scope. The finder scope is the small telescope on top of the main telescope.
