![]() | As reflected by the theme of this web site, my primary hobbies are astronomy and telescope making. I have also long been interested in metalworking, woodworking, electronics, embedded computer design and computer programming. I try to interweave all these activities as much as possible in my spare time activities. |
Hello, my name is John Upton. I am a 50-ish year old electrical engineer living in central Texas, USA. I am employed by a major computer design and manufacturing company. My job title is Senior Engineer / Scientist, but I actually just act as a technical consultant to an area involved in the design and development of computer systems ranging from $10,000 workstations to $300,000 commercial servers. My formal educational background is in science and engineering. I hold Bachelors Degrees in both Physics and Electrical Engineering from Lamar University in southeast Texas. In addition, I currently have four pending patents and two patents issued in the US and eleven other countries. These patents are all in the areas of computer architecture and design.
I first became interested in science in general and astronomy specifically when I received the book The World We Live In (a Time/Life book published by Golden Press) as a birthday present when I was 8. I looked at and read this book cover to cover countless times over the next 10 years. (I still have that book and it shows the use it got back then.) I found the chapter "The Starry Universe" captivating. This book and my demonstrated continuing interest in astronomy led to my receiving a 60mm Gilbert 80x reflecting telescope for Christmas when I was 11. With my first look at the moon and a few double stars, I was hooked on astronomy for life. By the time I reached high school, I was longing for a larger telescope. (This I now know is an affliction well known to all amateur astronomers.) One of the many astronomy books in the local public library was Neale Howard's Standard Handbook For Telescope Making. This book is what originally kindled my interest in ATM activities, though it would be years before I could follow up on that desire. Interestingly, the library also had copies of the original ATM series of books, but they never managed to capture my interest. I now value that series for its background and historical information, but I still heartily recommend Howard as the best practical guide to the beginner. My second telescope was a Criterion RV-6 6" equatorial Newtonian. I purchased this scope during my senior year of high school. I had worked for my grandfather remodeling houses all summer that year to earn the money. I wish I still had that scope, but I sold it years later while going to college for my second degree. While in college, I made my first mirror -- a quite bad 6". It suffered from severe turned down edge. After masking the outer 1/2", it made a very serviceable scope, though, and was donated to my old high school. I soon after made two 8" mirrors which were much better. These initial mirrors were all aluminized using the high vacuum equipment of the Physics department at the university. That in itself was a lot of fun. My third 8" mirror came out quite good. Several folks have tested it via Foucault and Gaviola tests and it always comes in about 1/15 wave on the surface. The mirror is very smooth with no discernible zones or roughness. It deserves a good home. I currently use it only very sporadically in an original-style Richard Berry inspired Dobsonian mount. It is currently uncoated, so I use it only for the very occasional solar eclipse observation. Someday I'll have to get around to making a decent mounting for that mirror. I currently use one of two commercial scopes for routine observation and public star parties. When observing from home, I use an older Meade 10" LX-3 SCT that I keep set up in the garage for quick trips to the driveway for observing. For public star parties, I use my Meade 7" Maksutov-Cassagrain. I would like to build a highly portable 14" scope for public star parties using a blank I have, but my limited construction time is now taken up with my 17.5" Dilworth Relay telescope project. I had originally envisioned this taking me about two years to complete, but I've been working on it for six months now with little to show at this point. I may have to extend my schedule to three years at some point. In any event, it will probably become my "retirement scope" so I theoretically have at least eight more years to finish it.
