A compound, or Schmidt-Cassegrain, telescope (occasionally called a catadioptric or Cassegrain telescope for brief) is a combination of two mirrors and just one lens. These scopes are best for viewing faint objects and may also do the job for viewing objects on this planet. As envisioned, we noticed strains that appeared comparatively straight and parallel to the edge, in lieu of the warped lines that will suggest some kind of aberration or distortion in the key optical device.

Credit history: @DavidSkyBrody Like all refractors, the Astro Fi 90 suffers from a bit of chromatic aberration; you will see a hoop of shade spectrum around brilliant objects given that the shorter indigo and blue wavelengths are bent extra (by the lens glass) compared to for a longer time, pink wavelengths.

From the chart you provide the outside of box setup time with the suggested scope as 25 minutes. But within the text you explained you were being up and managing in beneath quarter-hour. Sorry to nitpick. Thanks for that critiques.
