<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">It is important to remember that when viewing with a scope, the image is greatly magnified and the effect of ground borne vibrations is amplified.  I would guess that the seismic effects of some geysers would be sufficient to cause visible image effects when they are so magnified.  Think about the thumping at Doublet Pool, Sawmill or Oblong - if the scope were not isolated, it would wiggle enough to show effects at the eyepiece.<br><br>Bruce Jensen,<br> California, USA<br> ~~~~~~~~~~~~~~~<br> <br> "[Yellowstone] is a fabulous country, the only fabulous country;
