Dragonfly is a project by the Dunlap Institute for Astronomy and Astrophysics in Toronto, Canada. It consists in a multi-lens array designed for ultra-low surface brightness astronomy at visible wavelengths. It uses 10 commercially available Canon 400mm lenses. The lenses in the picture above seem to be Canon EF 400mm f/5.6L USM lenses.
The project was commissioned in 2013. The lens array should be capable of detecting the obscure and utterly complex structures that can be found around a galaxy:
According to Cold Dark Matter (CDM) cosmology, structure in the Universe grows from the “bottom up”, with small galaxies merging to form larger ones. Evidence of such mergers can be seen in faint streams and filaments visible around the Milky Way Galaxy and the nearby M31 galaxy.
Dragonfly is used to find those structures. How does it work?
Dragonfly is designed to reveal the faint structure by greatly reducing scattered light and internal reflections within its optics. It achieves this using ten, commercially available Canon 400mm lenses with unprecedented nano-fabricated coatings with sub-wavelength structure on optical glasses.
The Dragonfly project is funded by DAA Prof. Roberto Abraham’s NSERC Discovery Grant, with initial funds provided by the Dunlap Institute and Yale University, and an NSERC equipment grant awarded in 2013.

Canon U.S.A. Stands in Support of the National Center for Missing & Exploited Children at Yankee Stadium
Annual Canon Promotional Night Shows Commitment to Protecting Our Children
MELVILLE, N.Y., July 10, 2014 – Canon U.S.A., Inc., a leader in digital imaging solutions, hosted the Company’s annual Promotional Night at Yankee Stadium on July 1 with the National Center for Missing & Exploited Children and the New York Yankees. During a pre-game ceremony before the Yankees’ game against Tampa Bay, Ana Tavares, vice president, Finance & Accounting, Canon U.S.A., presented John Walsh, co-founder of NCMEC and John Arnos, NCMEC advisor, with a check in the amount of $508,213, representing the cumulative total of monetary and product donations Canon assisted in raising in 2014. As part of the celebration, the first 18,000 fans that entered the stadium received a Canon and Yankees branded baseball cap.
“Each year we enjoy Canon Promotional Night at Yankee Stadium with the National Center for Missing & Exploited Children and the New York Yankees because it is a night where we celebrate the efforts made to help bring missing children home,” said Kotaro Fukushima, senior director and general manager, Corporate Communications, Canon U.S.A. “Canon has been a sponsor of NCMEC for over 15 years and is proud to continue to support their mission of reuniting children with their loved ones.”
“We’re so grateful to Canon for its commitment to child safety and the National Center for Missing & Exploited Children,” said John Ryan, president and CEO, NCMEC. “They’ve been a dedicated partner for 17 years, providing technical and financial support that I know has helped save lives and reunite families, and I look forward to continuing that work with Canon by our side.”
Since 1997, Canon and NCMEC have worked together to raise awareness about the issue of missing and exploited children through the Canon4Kids program. As part of the Canon4Kids program, Canon has donated more than 2,200 pieces of equipment, including digital cameras, fax machines, printers and scanners, which have been distributed to law enforcement agencies in all 50 states, Puerto Rico and Guam. The program educates parents and guardians about how a current digital photograph is one of the most important tools to help locate a missing child.
