2010 Meteor Showers and Viewing Tips

    
    The next meteor shower is the Perseids on the night of August 12. The Moon is just a couple of days past new at the shower's peak, so there will be no moonlight to interfere with the faint meteors. The shower should reach its peak in the hours after midnight, with a maximum of a few dozen meteors visible per hour.



Where to Look in the Sky:
 The meteors will radiate from the constellationPerseus, which, in North America, rises in the evening in the northeast. You need not look in this direction, however. The Perseids are noted for their long trails and should streak across much of the night sky. Look anywhere from 30 degrees to 80 degrees above the horizon and about 45 degrees away from the constellation Perseus.  



So from the Fountain group, go around to the corner by Clepsydra-Morning and look towards the Thud group, that is more or less NE.  So to either side of that and up.  Take blankies and lie on the boardwalk if you can.

It is motorized so it can account for the earth/space movement (equatorial mount).  I know, I know, TMI.  LOL.  Inez

 Good explanation.  The scope we are using for taking pictures has a 25 inch mirror and a focal length of 125 inches.  It has it's own trailer.  We take long exposures (hours for each one) so vibration is a big problem.  Inez

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.

When you are taking lengthy exposures and have an open aperture the vibrations in the ground from eruptions will cause the picture to blur.  Try lying your hand on the ground when an eruption begins, you can feel it.  Inez

I have to ask about "wobble when eruptions happen."  Huh?  Can't imagine White Dome shaking your camera.  Please explain.
 
Sounds like great pictures, though.  I'd love to see some of these.

If you can, the best gazing is closer to White Dome, in the parking area.  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

Wondered if there would be other gazers in the park the night/s of the Perseids, August 12 (ish). If you've seen them, anyone got a recommended location? Madison Junction? Boardwalk at Fountain?
