    Default All You Want to Know about Bird-Jones Telescopes and More



    The Term Bird Jones is used to describe a variety of telescopes ranging from telescopes designed for and used by advanced amateurs to entry level telescopes (inexpensive spherical reflectors with a barlow lens corrector) frequently purchased by new comers to amateur astronomy. While these entry level telescopes are not true Jones Bird telescopes in the technical sense; this is the name given to them by a very high percentage of amateur astronomers and how they are known.

    Repeatedly, questions are asked on the forum concerning collimating or modifying Jones Bird type telescopes. This sticky is an attempt to centralize the information about collimating, using, or modifying Bird Jones type telescopes so that members can easily find information about how others use their Jones Bird telescopes or improved their performance.

    I. What is a Jones Bird Telescope: The Jones-Bird telescope design - the IS and ISN't

    II. Collimating an entry level Bird Jones type telescope:
