The Lost Valley Observatory:Astrophotography by Keith Quattrocchi

First Light for the Lost Valley Observatory occurred on June 3, 2007. Site updated monthly.

    Welcome to the homepage for the Lost Valley Observatory.  This observatory (my third) is located on a site at Sierra Remote Observatories, in the Sierra Nevada Mountains of California.  Sierra Remote Observatories is located between Yosemite and Kings Canyon, at a heigth of 4600 feet, where the seeing conditions are excellent (averaging 1-2 arc-sec, often sub arc-sec). For more information about this multi-observatory site please go to .  A YouTube video that summarizes SRO can be found on our SRO YouTube Channel.
   This website contains information on this current project as well as images and information from my prior observatory, which was located in Maine (MAS Observatory).  I hope the information and images will be helpful to other amateur astronomers and those with an interest in astrophotography.  The links to the left will take you to information about my observatories (past and present), and to images and articles.
   The first three links on the left contain information about this new observatory and images from the Sierra Mountain Site.  Below the first two links are links to images and information from the MAS Observatory (my previous observatory in Maine), which was closed in July of 2006.  Below these links are other links to images from the MAS Observatory (utilizing the RC or Takahashi 106 FSQ and Paramount ME), to articles and a few archived images from years ago.  I hope you enjoy the site.

Why amateur astronomy ? 
Not to get "carried away", but astronomical images remind me of  what first drew me to this "hobby" and to astronomy in general.  In a way analogous to other times in life, when looking into the sky there are unexpected sights which are invisible or nearly so.  At night we may see an area highlighted by nothing more than a small and generally blurry point of light, or perhaps nothing at all.  After hours of imaging and toiling over the computer, a stunning image appears.  For me, this process is inspiring and a reminder of what perspective means.  It also reminds of how little we really know and leaves me wondering about 'what else' I do not see or understand. 
A Note About Imaging and this Website:
I hope you enjoy this website.  The links are designed to take you through the history of my observatory (in some depth), to various image galleries, and to a few articles.  Building a fully robotic observatory with a solid mount and superb optics has been the fulfillment of a lifelong dream of mine.  Each of these images generally represents data collected over several nights of imaging and many hours (usually 10-20) of processing.  Each image is a labor of love and generally lessons are learned with every image.  Half the "fun" is the never ending "learning curve" which this "hobby" demands.  The rest of it is due to the unexpected findings and the enjoyment of the images in their own right

16 Step Greyscale Image for Optimal Viewing


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 the "greyscale" of your monitor.
