 Issues 
Due to its proximity to San Jose, light pollution and skyglow are an issue for the observatory. This was fine in the past, as San Jose used sodium ion bulbs, whose light were easy to filter out. However, due to safety concerns, LED lights which cannot be filtered out have been installed in San Jose. San Jose dims its lights when the observatory is active.
