These fields are located on Grinter farms, near Lawrence Kansas. The spot is about an hour from my home, and it’s free and open to the public.
I began my research on Google Earth to get an idea of the location and lay of the land. Then, using the Photographers Ephemeris and the PlanIt apps, I was able to determine where in the sky the Milky Way would be located in relation to the fields, and which days the (almost full) moon would be below the horizon to provide the darkest skies and clearest shot of the galaxy.
Using these tools, I found I would only have a 5 day window around the time the flowers were *supposed* to bloom to achieve the shot I wanted.
In the weeks leading up to the shot, I closely monitored the farm’s Facebook page to get updated on the progress of the flowers, which luckily looked to be lining up perfectly to achieve the shot. Once I realized the flowers would be blooming at the perfect time, I started keeping a close eye on the weather forecast desperately hoping for clear, calm nights.
Three of the nights showed clear skies before storms were to move in, and one in particular showed almost no wind. It was looking like it was all coming together, I had the night set and was ready to execute the shot.
I arrived at the fields about an hour before sunset so I could finally get a view of the landscape in person, and to snag a few sunset shots as well while I was there. After grabbing a few sunset pics and determining where to position myself for the shot, I just had to sit back and wait for the sky to darken and the milky way to move into position.
Once it was fully dark, around 10:30, I put on my head lamp (and full rain gear because I hate mosquitoes/ticks/spiders) and made my way out into the fields. I set up my camera and tripod, and while there was more light pollution on the horizon from the city light of Lawrence than I would have liked, the Milky Way was clearly visible–I knew I was going to get the shot I had hoped for.
For the wide view, it was a single shot, briefly waving around a small LED light panel during the 20-second exposure to light and emphasize the foreground flowers. For some tighter shots of the flowers, I used the screen of my phone to light them, and took two exposures to focus stack (one focused on the flowers, one on the stars).
The main photo was taken with my Nikon D750 with Samyang 14mm lens. It’s a 20 second exposure at f/2.8 and ISO2000.
The image went through basic processing for tone/contrast/saturation in Lightroom, using the radial filter tool to help minimize the light pollution in the sky and to bring out the detail in the Milky Way. Additionally, the focus stacked images were combined in Photoshop.
