Here's the message: Dear AOIE Members, It's with great sadness that I learned yesterday afternoon that David Lunt of Coronado Filters had passed away the day before, losing his battle to cancer. In a phone conversation yesterday evening, astrophotographer Jack Newton, a dear friend of David Lunt and his wife Gerry Hogan, said that David's work has touched millions of people. Lunt developed the solar filter for the first orbiting solar telescope, and had 40 years of experience in the field making filters for professional research. He then developed H-Alpha telescopes for the amateur market and started the company Coronado Filters in 1997 based on his technological advances in solar filter systems. David originally ran Coronado out of his home in the Chiricahua Mountains and moved the company to its present Tucson location in 2002. Meade Instruments purchased the company in 2004. Lunt's achievements in developing Etalon filtration to view the Sun changed the hobby for thousands of amateur astronomers. Surely, somewhere out there are children who are getting better grades, and people of all ages who are now looking at life in a more positive light because the views and images of our closest star as seen through his solar telescopes. In this way David touched the hearts and minds of innumerable people. David Lunt will be deeply missed. I will keep you informed as more information becomes available.
