Mr. Luke S. Walker, CEO Advanced Space Optics

Dear Mr. Walker,

We have taken some time and researched the five types of telescopes, as you requested. We assigned numbers to the following categories and ranked them from best (1) to worst (5), as follows:
 * 1) Extended Time
 * 2) Advanced Spectroscope
 * 3) Target Acquisition
 * 4) Wide Field
 * 5) High Resolution

Our rankings were based on the following facts:
 * 1) **__Resolution.__** We believe that this quality is one of the two most important things about the telescope. The resolution in arc seconds means the ability to clearly see a given size or distance. Since your company is researching astronomy being able to clearly see something through the telescope is most important.
 * 2) **__Spectrograph Range__**. This analyzes light coming through the telescopes. The spectrograph splits and disperses light for an object into its wavelengths. This way, it can be recorded and analyzed. We researched the range of other telescopes used in space and found that the range of 200-1,000 is good.
 * 3) **__Field of View__**. This is the amount you can see without your view being blocked by something else. It is measured by the angle of light in degrees, minutes and seconds.
 * 4) **__Time to Focus__**. The amount of time it takes to focus on an object.
 * 5) **__Maximum Viewing Time__**. The amount of time the telescope can focus on one object before being blocked by something else.

We chose the Extended Time telescope because it has a very good resolution, spectrograph range, and field of view. Also, it has the longest viewing time. Even though it takes a long time to focus, the telescope can still view an object for over an hour and a half. This is important when doing research. Even though the Advanced Spectroscope has better resolution and spectrographic range, the field of view is not as good, and you could only view an object for a maximum of 30 minutes. We feel that the Extended Time telescope is better for you because even though it is not the highest resolution, it is very good. Also you would be able to observe objects for much longer period of time. This is important for your research.

This is how we ranked the telescopes. Thank you.

Sincerely,
