​The Lost Valley Observatory

My first dedicated observatory, the MAS Observatory, was built in 2003 in Greene, Maine.  The new observatory, The Lost Valley observatory, is located at Sierra Remote Observatories (SRO), a group of observatories in the Sierra Nevada Mountains.  Mel Helm and I founded SRO in 2007 and it has been continuously operational since.  You can visit SRO at www.sierra-remote.com.   
  The Lost Valley Observatory is located at Sierra Remote Observatories at 4,610 feet, above the inversion layer of the central valley in the Sierra Nevada Mountains.  It has unique seeing conditions, averaging 1.0 arcsecond with very dark skies (22 magnitudes/sq arcsecond). The average wind speed is only 1 mph with most nights (65%) clear with no summer monsoons.  Thunderstorms are rare. It is an ideal site for data acquisition, satellite tracking and communication.

16 step greyscale.  An optimally balanced monitor will show all 16 steps as clearly defined.
In order to properly view the images on this site your monitor needs to be standardized, otherwise the images you view may look VERY different than those others see.  To do this, be sure the 16 greyscale gradations in the above image are distinct.  If they are not, adjust the brightness and contrast of your monitor until they are.  Proper color calibaration of your monitor (e.g., use of PhotoCal or other monitor standardization tool) should standardaize color and therefore the "greyscale" of your monitor
