This article is documenting a series of telescope and camera test combinations of a terrestrial image to learn about the relative sizes of the resulting images.

Telescopes:

  • Meade ETX90EC
    • 90 mm or 3.54”
  • Meade LX70 refractor
    • 120 mm or 4.724”
  • Meade Lightbridge
    • 254 mm or 10”

Cameras:

  • Canon T3i
  • ZWO AS103MC


The target was the top of an electrical pole a few blocks away from my house. I had the telescopes pointed out my office window through the glass. I tried to focus but didn’t worry if not in focus since during daylight and pointed through a window. Here is the image using the Canon T31 with the lens at 55 mm focal length.
