Image stabilization and tall buildings

[Manofmayo66]

Just finished going through my night photography shots and nearly 90% of the shots taken with the Tamron 90 VC (F017) are unusable due to vibrations. When I would take a picture, Mirror lockup was engaged, 2 second timer, 3 image bracketing, and I would stand still all to minimize potential vibrations.

A sample crop is here (I couldn't seem to upload the file):

Did you turn off VC?
