Nightsky - a very quick summary of the above:
1. Pier set-up properly - fantastic platform for any type of fixed location astronomy - saving time, more secure and robust, more stable, less prone to vibration, no risk of being knocked over.
2. Wedge - one of the two key options needed for fork mounts to avoid star rotation for longer duration astro photography. The other option is a field de-rotator that rotates the eye piece or really a ccd so that star field rotation is counter acted.
So for a fork mount a pier on a wedge or more simply a pier with a top mounting plate machined to an angle of your locations exact longitude would be a great asset - and not too expense or difficult to make for yourself if you do some planning.
