Outline  Intro  Design goals and challenges  Elements of the All-Sky Camera Project  Importance and benefits  Conclusion  Acknowledgments…

Intro  Built three for Mauna Kea, Mauna Loa, Cerro Armazones in Chile  Cloud coverage  Collect and store images  Monitor weather conditions

Design Goals and Challenges goalschallenges  INEXPENSIVE  Efficient  Withstand altitude  Reliable  Ventilation  Lens fogging  Snow buildup  Wind resistance  Lightning  Water proof

Elements of the All-Sky Camera Project  Camera Hardware  Housing  Operation

Camera Hardware  StellaCam III camera  StellaCam III control box  Controls gain, frame, gamma  Fujinon lens  Automatic iris

Design Process 1. Brainstorming 2. Researching and sketching 3. AutoCAD 4. Get approval

AutoCAD Drawings

Design Process for Housing 1. Brainstorming 2. Researching and sketching 3. AutoCAD 4. Get approval

Design Process Cont. 5.Cutting, sanding, polishing, gluing, and bolting 6. Install camera, lens, sensor, and fans 7. Wiring

Housing  Junction box  Two fans  Heat sensor  Fish-eye lens  Metal ring  Rubber gasket  Brackets  Spacers and aligner

Finished Products

Operation  Seeing real-time images  Observing cloud coverage  Get 1440 perfect images over a year  No cloud and moon  Take an image every minute

All-Sky Images Day Time Cloudy Night Clear Night Full Moon Night

Importance and Benefits  Better understanding of observing conditions  Clearer images of the night sky  Reliable data for archiving  Accessible to every telescope on Mauna Kea and Mauna Loa and Cerro Armazones in Chile

Conclusion  Planning and brainstorming was important to ensure us that our finishing product would be successful  Team work was the key to success  Gained a lot of real-life experience and knowledge to apply in my future endeavors  Satisfying to see working camera as a result of my work
