The first thing you need to do after assembling the telescope as planned is center the desired object in the finderscope’s crosshairs. Provided you did a reasonable job aligning the finderscope, a quick look through the main telescope tube at low power should reveal the same image.

  • Page 10: Helpful Hints

    1. Your telescope is a very sensitive instrument. For best results and fewer vibrations set your telescope up on a level location on the ground rather than your concrete driveway or your wooden deck. This will provide a more stable foundation for viewing, especially if you’ve drawn a crowd with your new telescope.
