Nine-Years Ago (14-August-2010) — Iowa

Gone to See America August 2010 Road Trip. Day 14: Waterloo, Iowa to Columbus, Ohio.

Nine-years ago, I was returning from a cross country road trip. I stopped a a rest area along the interstate highway an saw where they planted a Prairie Wildflowers display. It had attracted a number of different butterflies. Images taken with a Nikon D3s camera and 24 mm f/1.4 lens or a Nikon D3x camera and 80-400 mm VR lens. At that point I said:

This is what I want my backyard to look like…

I’ve been trying for several years — fighting the deer, mile-a-minute vine, too much rain, too little rain. This year I am getting pretty close to having my own Wildflower Meadow. Images below are what I saw in Iowa back then. If you have been following my Photoblog recently you have seen the Butterflies, Hummingbird Moths, and Wildflowers in my Backyard this spring and summer.

Backyard Summertime Nature in New Jersey.

Daily Walkabout: I went out with a Fuji X-T3 camera and 200 mm f/2 OIS lens. Butterflies (Spicebush Swallowtail, Silver-spotted Skipper, Monarch, Painted Lady, Common Buckeye, and Tiger Swallowtail). Bumble Bees on a variety of Sunflowers. Leaf-legged Bug on a Thistle, and an ant on a Bee Balm.

Daily Electric Energy Used (60.3 kWh) from Sense and Daily Solar Electric Energy Produced (25.5 kWh) from SolSystems and Locus Energy. A load of Laundry (3.7 kWh) and two loads in the dishwasher contributed to the increased energy used. The sky was cloudy most of the day (but no measurable rain) impacted the solar production. Daily net deficit 34.8 kWh.

Backyard Summertime Night Sky Over New Jersey.

Night three trying to capture some of the Perseid Meteor Shower. Again with two cameras out 1) Nikon D810a camera with a 8-15 mm fisheye lens (ISO 800, 8 mm, f/4, 8 sec) and 2) Nikon D850 with a 19 mm f/4 PC-E lens (ISO 800, 19 mm, f/4, 8 sec). The sky was mostly clear, but the moon was bright. After reviewing the images, I did see a few meteor trails. Mainly in the fisheye images where more of the sky was covered.

Backyard Summertime Night Sky Over New Jersey.

Night two trying to capture some of the Perseid Meteor Shower. This time with two cameras out 1) Nikon D810a camera with a 8-15 mm fisheye lens (ISO 800, 8 mm, f/4, 8 sec) and 2) Nikon D850 with a 19 mm f/4 PC-E lens (ISO 800, 19 mm, f/4, 8 sec). After reviewing the images, not must luck. In order to process this many images I have four Surface computers running full time and at full power. By full power, I mean all four cores on the Microsoft Surface Studio 2 (with a dedicated video processor) are running hot — close to 100 °C (45 watts). The computer automatically shuts down if these temperatures are exceeded. The Microsoft Surface Book 2 (with a dedicated video processor) has this bad habit when being stressed to run only on the battery until the battery runs out even though it is plugged into an external power supply. So I had to go back and forth between the four computers to monitor how they were doing. My power usage for the day was nearly 4 kWh larger just because of the extra processing work being done by the computers and servers. Just glad it was a bit cooler outside and the sun was out most of the day to charge the solar panels.

Backyard Summertime Night Sky Over New Jersey.

The weather forecast indicated the night sky would be relatively clear for a couple of nights. I hope to capture some of the annual Perseid Meteor Shower. The moon would be out for part of each night, so not ideal conditions. But I figured I would try. I set up a Nikon D810a camera with a 8-15 mm fisheye lens (ISO 800, 12 mm, f/4, 8 sec) to capture images all night (2550 images in total). It takes a lot of time to process all of the images for a Time-lapse video, and several Star Trail images. Lots of Jet Trails. How many Meteor Trails do you see?  The Time-lapse Video is best viewed in a dark room.
