Vibration isolator pads. Made of 2" x 2" x 1" cork and neoprene pads. These are an inexpensive alternative to the isolation pads sold by the bigger companies.

These compact isolators are perfect to dampen vibrations when observing or imaging. They measure 2" x 2" and are just the right size for any tripod. They can even be used on piers in observatories where vibration is an issue.
