Hi,
The cp4300 can produce some very good results when digiscoping, though you need the Nikon UR-E2 adapter to give a 28mm thread in front of the lens for a digiscoping adapter to be used.
The Nikon remote MC-EU2 can be used with the cp4300, or you can use the cable-release adapter brackets available in the U.K. from
www.EagleEyeuk.com or Jessops ... though the sloping shutter release button does make things harder for these.
regards,
Andy
