A Dream Becomes Reality. Levy has spent a lifetime inspiring people of all ages to look at the stars through his comet discoveries, his writings, and his lectures. His dream to show people the beauty of the night sky has culminated in the formation of a non-profit organization devoted to outreach in astronomy, called the Sharing the Sky Foundation. But outreach on a global scale takes sustained effort and money.
Our company shares David's dream. So we embarked on a project to co-design a telescope with Levy that could help support Sharing the Sky through through the sale of the product.
Called the David H. Levy Comet Hunter, the instrument is a rich field telescope (RFT), capable of showing faint objects over a wide field of view (generally two degrees or more). Comet hunters like Levy use RFTs to visually sweep the sky for comets, but this type of telescope is also preferred for observing all types of faint, deep sky objects such as nebulae and galaxies. The Comet Hunter comes standard with a two-inch, 30mm focal length eyepiece with a wide 70ý apparent field. This eyepiece combined with the short focal length of the telescope produce an amazing 2.86 ý true field of view with a 6.2mm exit pupil.
Sometimes called visual equalization magnfication, using the right low power eyepiece eyepiece will produce an exit pupil that nearly matches the fully dialated eye. This allows you to see to the faintest observable limit of the telescope's aperture, which is critical for searching for faint objects such as distant comets. We selected a 30mm eyepiece as standard equipment because the exit pupil it produces comes close to the average fully dialated human eye.
