<table border="0" cellpadding="0" cellspacing="0"><tbody><tr><td style="font: inherit;" valign="top">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>

<div>I have to ask about "wobble when eruptions happen." Huh? Can't imagine White Dome shaking your camera. Please explain.</div>

<div>Sounds like great pictures, though. I'd love to see some of these.<br>

<div><font face="Arial, Helvetica, sans-serif">If you can, the best gazing is closer to White Dome, in the parking area.</font> Ask at the back country ranger office if you can stay after they lock the gate. We have taken the big scope these and gotten some nice exposures, the kind that take an 1-6 hours or more each for each picture. The wobble when the eruptions happen can be a problem, so you may want to take a thick rubber mat. Ours is 6' x 8' and an inch thick. You will have problems with head lights at any other basin and trees at Madison. Another thought would be closer to Ojo Caliente, we haven't tried there, tho. Inez<br>

If you've seen them, anyone got a recommended location? Madison Junction? Boardwalk at Fountain? <br>
