Almost all star charts have instructions printed on them. Also; there are HUNDREDS of sites on the internet with these instructions...LOOK THEM UP. "Answers" is best used to help you with questions you can't find or don't understand elsewhere. Do you want someone else to Google "STAR CHART INSTRUCTIONS" then copy and paste them here for you? Don't be lazy.

You'd need either the OFFICIAL name/designation of the star, or its celestial coordinates (right ascension and declination). Even then, you may have picked a star that's never been catalogued and there'd be no data on it. If you do have the star's celestial coordinates, try this website --> http://www.telescope.org/\n\nThe website gives free access to their telescope so that users can remotely photograph celestial objects they're interested in.

The only way that I know to do this with a normal telescope is to compare the star with others nearby of known magnitude and try to decide if it's brighter or dimmer until you find the same.\n\nOtherwise you'd need to measure the amount of light that comes from it, and I think you need computers to do that.\n\nThe magnitude scale is exponential, so deciding a magnitude ain't that simple. (ie a star of magnitude +2 is ten times brighter than a star of magnitude +3)

First find the Big Dipper constellation (Ursa Major) Find the two stars farthest from the dipper handle. Draw an imaginary line from the bottom star through the top star and extend the line outward. The first bright star your imaginary line comes near is the North Star---that's north.\n\nThe website shown has a diagram of the above.

When performing star counts, astronomers consider many different categories which have created been to classify a few stars that have been well studied. One of the hopes of studying the results of star counts is to discover new categories. Different counts typically seek to categorize stars for only a few of the qualities listed below, and determine how common each considered quality is and how stars of that kind are distributed.\n\nTemperature. In astronomy, temperature is usually shown using the letter codes O B A F G K M L T running from blue (type O) through white (type F) to red (type M). Types L and T are used for brown dwarfs, whose 'colors' are in the infrared. \nSize. Size is usually designated by Roman numerals I (supergiants) through V (dwarfs). \nAge. Stars are usually grouped into Population I (young) and Population II (old). \nLocation. In the Milky Way Galaxy the groups are described as thin disk, thick disk, central bulge, and halo. \nMultiplicity. Most stars appear to be members of double star or triple star, or even double-double star systems. Our own sun appears to be rare for not having a companion star. \nThere are many finer subdivisions in all of the above categories.\nIn which category you want me to count the Stars.

There are a couple of ways. One uses diffraction effects or speckle interferometry to estimate the angular size of the star. Once the distance to the star is known, the actual size can be determined fairly easily. This method can only be used for very large stars (such as red giants) or very near stars.\n\nFor other stars, we determine the temperature of the star via the spectrum. This tells how bright the star is per unit area. Then, we look at the distance and apparent brightness to determine how bright it is overall. Dividing will give the surface area of the star, and hence its size. The difficult here is that the temperature of the 'atomosphere' is usually much higher than the surface of the star and this can significantly affect the estimates. Also, if the star isn't spherical (because of rotation, for example), the surface area alone won't give all the information about its size that might be desired.

Select your data. You have already entered your data, right?\n\nPull down the "insert" menu to "chart". Choose "line", choose the particular line graph you like best. Hold down the sample bar to see if the graph looks the way you expect it to. If you aren't making any changes, you can pretty much click "next" until you get a chance to click "finish".

Your question is too vague. First of all, the first sentence says "Give ex of each type of charts you have mentioned above." But you haven't described any charts. How would anyone know what the charts are like? Unless you can provide more information, it's unlikely that anyone can help you.

There are a wide variety of charts. Wikipedia has articles on a wide variety of them. OpenOffice has free charting software available for download.

Look up in an appropriate table (e.g., reference) the wavelengths of the indicator lines, and then use those to lay out a scale.  The sodium D-lines can also be used, because they are so prominent, although they are not as narrow as one might like.

You can try to count the stars, but there are as many stars in the Universe as there are grains of sand on the beach.  It would be a very difficult task and take millions of lifetimes to complete.  Sorry.
