Things You’ll Need:
 
* A cell phone with a camera
* 2 mini tripods - Vanguard VS55 Mini Table Tripod
* Cell phone belt clip that fits your phone without covering the camera lens
* 13/64” drill bit and ¼-20 tap
* Monocular telescope - I used a Zeiss 10 x 25
* 1” pipe clamp to mount the monoscope
* ¼-20 nut
 
 
Technical information:
 
The focal length of a digiscope system is calculated by multiplying the focal length of the digital camera lens by the magnification of the spotting scope (If your are using a 10 x 25 monocular the magnification would be 10).  For example, when a 3X zoom digital camera with a 100mm focal length (35mm equivalent) and a 10X spotting scope are combined, the effective focal length will be 1,000 mm (100 x 10).  A digiscope system simulates long focal lengths for capturing super telephoto images.
