You may be asking what is digiscoping? It is exactly what it sounds like. You place a digital camera up to the eyepiece of a microscope or  telescope and take photographs.

To see photo samples use the buttons to the left. The calculators page has formulas to determine what cameras work well with the telescope of your choice.

I currently use a Celestron C90 Mak spotting scope. The specs are:
Aperture: 90 mm (3.54 in)
Focal Length:  1250mm
Focal Ratio #: 13.89
Magnification:  39x
Eyepiece: 32 - 22mm eye relief
Angular Field of View:  1.3
Optical Tube Size: 16in by


I use 2 different cameras for different purposes. The Nikon P100 does 1080p HD video and has a long reaching 26x zoom to view large planets and the moon without a scope.

The Canon A720 IS is great for digiscoping with a 6x optical zoom. It does well with daylight nature observing but suffers more with night time astrophotos. The Nikon has a backlit sensor that captures the stars and planets much better.
