Last night I noticed that my stars were trailed, despite collimation being perfect, and tracking being perfect. It turns out my ASI2400 fan was causing unguidable, high frequency vibration.
This morning I opened the casing up to reveal about 8 dead, minced up bugs inbetween the peltier unit and the fan blades, causing the oscillations. I suspect a lot of other user's vibrations are caused by this same issue.
I'm going to put a mesh on the fan and peltier ducts to prevent this from happening in the future and I recommend others do so.
