     DETAILED DESCRIPTION OF THE INVENTION 
       FIG. 1  is a perspective view of an adapter  50  that attaches a mobile device  52  to optical device  54  accordance with an embodiment of the present disclosure. As used herein, “mobile device” refers to a smart phone, cell phone, or other portable telecommunications enabled device. In the illustrated embodiment, the optical device  54  is a spotting scope, but could be a variety of other devices, such as for example, a microscope, binoculars, a telescope, a rifle sight, and the like. An exemplary optical device  54  is disclosed in U.S. Pat. No. 7,271,954 (Perger), which is hereby incorporated by reference. 
     In the illustrated embodiment, the adapter  50  is releasably attached to eyepiece  56  on the optical device  54  by flexible adjustable device  58 , such as for example, a strap. The flexible adjustment device  58  permits the adapter  50  to be attached to eyepieces  56  of various sizes. The large surface area of engagement between the strap  58  and the eyepiece  56  reduces the risk of rotation of the adapter  50  relative to the eyepiece  56 . The strap  58  preferably wraps at least 180 degrees, and more preferably at least 220 degrees, of the outer surface of the eyepiece  56 . In one embodiment, the strap  58  include a high friction coating, such as rubber or silicone, to increase fixation. 
     The flexible strap  58  can be constructed from various woven fabrics, films, molded structures, and the like. A variety of other mounting structures can be used to attach the adapter  50  to the eyepiece of an optical device, such as for example, molded clips, adjustable compression members, suction cups, releasable adhesives, and the like. 
     The adaptor  50  serves to align the camera lens  100  (see  FIG. 6 ) on the mobile device  52  with an optical axis  60  of the optical device  54 . As a result, touch screen  62  on the mobile device  52  displays the image captured by the optical device  54 . In the illustrated embodiment, the magnified image captured by the optical device  54  is displayed on the touch screen  62 . 
       FIGS. 2 through 4  illustrate the adapter  50  separated from the optical device  54 . Side supports  64 A,  64 B and bottom support  64 C (collectively “ 64 ”) are configured so as to not obscure the touch screen  62  or any input buttons on the mobile device  52 . In the illustrated embodiment, side support  64 B and bottom support  64 C are fixedly attached to base plate  68 . Side support  64 A slides on shafts  70  along axis  70 A relative to the base plate  68 . Springs  72  bias the side support  64 A toward the side support  64 B so as to compressively engage the mobile device  52  to the base plate  68 . 
     Optical interface  80  includes opening  82  surrounded by shroud  84  that preferably engages with rear surface of the mobile device  52 . The lens  100  of the mobile device  52  is aligned with the opening  82  and the shroud  84  serves to reduce the amount of ambient light reaching the lens  100 . 
     Latch  86  is attached to the optical interface  80  to capture distal end  88  of the flexible strap  58 . In the illustrated embodiment, the flexible strap  58  wraps around the eye piece  56  of the optical device  54 , around pin  90 , and back to the latch  86 . In the preferred embodiment, the flexible strap  58  is the sole mechanism for attaching the adapter  50  and mobile device  52  to the optical device  54 . 
     As best illustrated in  FIGS. 5 and 6 , the base plate  68  is attached to housing  92  by traveler  94 . The traveler  94  rides in a slot  96  in the housing  92  along threaded member  98 . Knob  102 A extends beyond the adapter  50  to facilitate rotation of the threaded member  98  in order to displace the traveler  94  along axis  126 . 
     As best illustrated in  FIGS. 3 and 4 , the traveler  94  includes an extension  104  that resides in slot  106  in the base plate  68 . Threaded member  108  engages with the extension  104 . Rotation of the knob  102 B moves the base plate  68  relative to the extension  104  along the axis  128 . 
     Turning back to  FIG. 6 , the housing  92  is attached to the optical interface  80  by threaded member  120 . Thumb screw  122  is provided to secure the housing  92  to the optical interface  80  at the desired rotational orientation  124 . 
     The position of the mobile device  52  relative to the optical interface  80  can be adjusted by turning the knobs  102 A,  102 B (“ 102 ”). Rotation of the knob  102 A displaces the base plate  68  along axis  126  and rotation of the knob  102 B displaces the base plate  68  along the axis  128 . The threaded members  96 ,  98  permit micro-adjustment of the position of the lens  100  on the mobile device  52  relative to the eye piece  56  of the optical device  54 , so that precise alignment is achieved. 
     With reference to archery and bow hunting, for example, the hunting experience can be greatly enhances by adding one of the following applications to the mobile device  52 .
