Default Digiscoping

Hi Jedi,
Digiscoping is using a digital camera in combination with a telescope to take images which would otherwise be difficult or impossible to do.

There are two basic types of telescope used for digiscoping:

1. The terrestrial spotting scope like a Leica 77, Pentax 80, Swarovski 80, etc. These telescopes are relatively expensive starting at near $1000 U.S. and going up from there. The advantages are light weight, variable power eyepieces, waterproof, etc.

2. An astro-telescope like the Meade ETX-90, Celestron, etc., which uses a refractor system (mirror) and is actually designed for viewing the planets and stars. Many of the companies have converted some of their popular models to "spotting scopes" and are available at very reasonable prices, sometimes as low as $190 U.S.

The advantages of the astro-telescope are: no chromatic aberration, low price. The disadvantages are that they are fairly delicate.

With both the above systems, one must use either a specialized eyepiece or an adapter to hold the camera's lens in close proximity to the eyepiece of the telescope.

Fixed lens digicams with small lenses like the Nikon CP990, etc., are especially useful with digiscoping because they can "see" through the eyepiece of the telescope with minimal or no vignetting (shadowing in the corners) depending on the extent of "zoom" used. Removable lens SLR's can also be used with telescopes, but require fixed focal length ports and therefore are less versatile for this purpose.

Best regards,

Lin
