Yes.... and probably 20 other things you have not heard about.
Dampening down any kind of vibration is important for imaging and viewing, especially at high magnification. Some people fill their pier with concrete or sand, but that adds thermal mass. Big "fins" on a pier are a good idea for a lot of reasons but I fill mine with expansion foam. Lots of threads about this on the topic. For gawd sake, avoid the "rats cage" thing...
