My reason for posting these vids was to show how many fallacies become gospel in the amateur astro community. These vids do go some of the way to dispel the myths about pier design.

My background is in Applied Physics and we prefer to analyse any system from first principles with a minimum of assumptions. We then take the simple step of measuring this putative system to see if our ideas are valid.

I only wanted people to think about what was happening with their system.

Is your continuous poor astro photographic 'seeing' due to pier and/or mount oscillations?

It was never about denigrating any system.

I tightened the bolts holding my pier to the concrete block far higher than I did initially. The rms errors in guiding have nearly halved to better than 0.5" ! It could be that I have suddenly been blessed with better seeing. My exposure for guiding was two seconds so this should eliminate seeing. Only time will tell.
