Mr. Luke S Walker CEO Advanced Space Optics

Dear Mr. Walker:

We have taken some time and researched the eight types of telescopes, as you requested. We assigned numbers to the following categories and ranked these telescopes from best (1) to worse (8), as follows:
 * 1) Wide Field-2
 * 2) Extended Time-5
 * 3) Advanced Spectroscope-4
 * 4) High Resolution-2
 * 5) Target Acquisition-6
 * 6) Semi-Wide Field-8
 * 7) Precision Spectroscope-6
 * 8) Massive Duration-1

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
 * 6) __**Maximum Life span**__. A measure of the maximum amount of time one or more members of a population has been observed to survive between birth and death.

After further research, we discovered that the Massive Duration telescope is even better than the Extended Time telescope. The resolution was better, the field of view was wider, the maximum viewing time was doubled, and it has the longest lifespan than any other telescope. The rest of the telescopes were ranked from best to worst based on the six items listed above. We hope this information helps you in making your decision.

This is how we ranked the telescopes. Thank you.

Sincerely, ICS16COV Facts
 * 1) All 8 telescopes have Resolution and they're (Arc Seconds).
 * 2) They also have Spectrograph Range and that's (nm).
 * 3) All the telescopes have Field of View and that's also called (Arc Minutes).
 * 4) Telescope 8 has the highest Resolution and it's 0.15.
 * 5) Telescope 3 has the highest Time to Focus and it's 15.
 * 6) Telescope 8 also has the highest Max Viewing Time and it's 240.
 * 7) Telescope 7 also has the highest Spectrograph Range and it's 50-2000
