Planning and Constructing the Big Bear Observatory P. Kelly, J.A. Wise 1. Introduction This paper stems from a larger research question regarding the documentation and analysis of celestial events, as observed from Southern California. The WISRD RECON (Research and Education Collaborative Occultation Network) team had intentions of setting up the WBBO (WISRD Big Bear Observatory) that would have created a permanent viewing site for our future The main goal of our research was to design and build an observatory that would serve as an efficient method of gathering data. In concert with this, our team investigated the use of different means and methods to evaluate the constructability of a roll off observatory. 2. Location Big Bear Lake was chosen as the site for the WISRD Observatory. Located 6,760 feet above sea level, Big Bear Lake in the San Bernardino Mountains provides better viewing conditions for astronomical observers. Big Bear was chosen due to the problematic factors and limitations of constructing such an endeavor in Los Angeles. Initially, comparisons were drawn between Big Bear and our school’s location in Los Angeles. Challenges were revealed that would need to be addressed if we were to utilize our location in Los Angeles. After careful consideration, Big Bear became the preferred location. 2.1 Light Pollution Light pollution is caused by inappropriate or excessive artificial light. Light Pollution primarily affects our view of extended objects, such as nebulae and galaxies. Light Pollution can affect various wavelengths of light, some more than others. It is possible to filter out amounts of the unwanted light pollution to better improve views of extended objects to a certain extent. WISRD currently minimizes light pollution by using a CCD Camera and subtracting background “noise.” Components of light pollution include: robotic telescope system. 1.1 Overarching Goal

● Glare – Excessive brightness that causes visual discomfort. ● Skyglow – Brightening of the night sky over inhabited areas. ● Light trespass – Light falling where it is not intended or needed. ● Clutter – Bright, confusing, and excessive groupings of light sources.
