PROBLEM TO BE SOLVED: To provide an attachment which has an eye pad function, is easy to carry and easily connects a camera to a telescope. SOLUTION: An eye pad ring 5 is accommodated in an attachment part 3 so that the ring concerned may move toward and rotate about the center axis of the attachment part. An operation ring 7 is arranged between the attachment part 3 and the eye pad ring 5 so that the ring 7 may rotate about the center axis, and a part of the operation ring projects from the attachment part 3. A cam mechanism is provided, which transmits the rotation of the operation ring 7 to the eye pad ring 5 to move the eye pad ring 5 toward the center axis of the attachment part 3.
