I'm Greg Comegys and this web site is dedicated to my astronomy interests, including pictures of my equipment & a few astro-images I have taken.  It also includes several PowerPoint presentations that I have presented to the Grand Rapids Amateur Astronomy Association.  (see  files section).  My wife and I live on 9 acres in Caledonia, MI, and I retired after 42 years of aerospace engineering.  We have 10 grandchildren.
