Attach your SLR or CSC camera to your spotting scope in a matter of seconds and take photographs at long range, perfect for wildlife photography and astronomy. This accessory is required to attach an SLR or CSC camera to a spotting scope with a 42mm diameter eye piece thread. The tube fits over the spotting scope eye piece and the appropriate T2 mount that fits your camera (not included) will also be required to complete the camera attachment.
