Monday an image was sent to the AAVSO email account and forwarded to the staff. It was a picture of epsilon Aurigae and the surrounding star field taken by John Chumack, an AAVSO member and as it turns out, a professional astrophotographer.
I was so impressed by the image I emailed John and asked him if he would grant me an interview so I could learn more about him, his connection to the AAVSO and his obvious love for the night sky.
As it turns out, John has been sharing his work with the AAVSO and the world for twenty years now. Shortly after embarking on his new career he got involved with AAVSO assisting with the educational program 'Hands On Astrophysics' in the 90’s.
“ I was the astrophotographer for it. At the time (1993-1996) I worked with Dr. Janet Mattei on the project. I think there were 52 other astrophotographers that put in proposals, but out of all of those they chose me. That was my first grant, so that was awesome.
I started in ‘89, working on NASA’s Ulysses Project, which was to image comets to measure the comets’ ion tail, and then correlate that data with the Ulysses spacecraft."
So how does one become a professional astrophotographer?
"It got started as a hobby, but I’ve been doing it for a living for the last twenty years. I designed my own 16-inch telescope, a big fork-mounted equatorial, and the drive system for it, using a tape measure and a 1-horsepower motor. I took that to Astrofest in Chicago, three days after I finished it, and won an award for the design. I took it home and the local newspaper did a write up on my award. I started shooting the night sky with the telescope after that.
I started sending in photographs to Astronomy magazine, getting published in Astronomy and Sky and Telescope as well. About a year after my start, a stock photography company out of New York contacted me, they saw my images in the magazine, and wanted to represent me here in the US. Now I have agents in 35 countries selling my work world-wide.”
I asked John what inspired him to do an image of epsilon Aurigae.
“Well I’ve done shots of that part of the sky before, constellation images of Auriga and that area. I’ve got over 35,000 images. I image the sky prolifically; I’m constantly out there. Now I have an entire observatory complex in Yellow Springs, Ohio, where I have multiple scopes running at the same time.
I remembered reading about this mysterious variable that’s been stumping astronomer since 1821 or something like that, so I thought let me go take a shot of this star. I know I have wide-field images of it, but I don’t have any close up shots of it. So I took about a total of 45 minutes exposures, several images stacked, they’re about 5 minutes apiece.
Once I had the picture I was looking at the field of view there and I noticed that the stars are evenly distributed across the entire field, except for the one quadrant. If you look at the image, from about 3 o’clock to 6 o’clock, it’s devoid of stars. So that tells me right there that there is a large dark molecular cloud blocking the light from background stars.
Anyway, I thought it’s a nice picture of the star and if the AAVSO is trying to encourage people to do observations of this thing, so we can figure out what’s going on with it, well, we need to get a pretty picture of it. I’ll send it to them, maybe they can use it.”
John’s excellent website is called Galactic Images.com. You can find examples of his work and a schedule of art fairs and shows he will be exhibiting at this year. After talking with John for a while, and looking at pictures of him at his observatory, I realized we’d met before at Arts, Beats and Eats in Pontiac, Michigan a few years ago. I remembered him telling me about his 16-inch telescope and ogling his fantastic images. Small world, eh?
Sometimes we get so wrapped up in the science, we forget just how stunningly beautiful many of these subjects are. Thanks for the picture, and the reminder, John.
