Instructions

    • 1

      Resolve to invest a fair bit of money in this telescope. You can easily spend $1,000 per inch of aperture on an apochromatic refractor - without the tripod.

    • 2

      Accept that the lower-cost models have limited light-gathering power and suffer from chromatic aberration. Chromatic aberration is color fringing around the object you are viewing.

    • 3

      Know that apochromatic telescopes use three or four lenses to eliminate chromatic aberration. This is the main reason they are so expensive.

    • 4

      Enjoy the advantage of an apochromatic refractor, which is never having to say the word "collimate." This type of telescope comes pre-assembled from the factory with all of its optics aligned.

    • 5

      Enjoy that this type of telescope requires little care and maintenance.

    • 6

      Plot your subject with the use of star charts.

    • 7

      Position your telescope for viewing.

    • 8

      Aim the telescope at the sky and find your subject.

    • 9

      Position your eye over the eyepiece and focus.
