Milky Way Astro over Old Barns & Cribs

Equipment Used: Nikon D750, 24-120mm f4 lense, 35mm f1.8 lense, SB-700 Speedlights, led flashlight, Vanguard Abeo Plus 363 CT Tripod & Viltrox Wireless Remote Control

The Exsate Golden Hour app on my phone says “Someone told you the most beautiful stars are in August? You have to check!” I ventured out to see if this was true from August 1 – 3 when the sky was clear between 10:30 to well after midnight. I traveled to four different locations to capture the Milky Way.

The D750 was fitted with the 24-120mm at f4 and the 35mm at f2. It was the first time I used the 35mm lense to capture the stars and I was pleased with how much light it gathered but need to fine tune the manual focusing. The camera was placed on my new tripod that is sturdier than my previous one and also easier to set up in the dark. Settings on the camera were manual mode with exposures ranging from 10 to 30 seconds at ISO 3200-8000 with VR off on the lense and high iso nr set to low. For the best in post processing and enlarging the files, RAW was used as well. While my camera was exposing for the milky way, I used the SB-700 in manual mode to throw bursts of light at the foreground which included the barns I was trying capture.

Capture NX-D processed the RAW files into Tiffs with adjustments to enhance the image. Exposure compensation was increased while white balance was either left alone or changed to direct sunlight or incandescent. The picture control was changed to vivid or landscape or also left alone. The contrast, saturation and shadow sliders were adjusted if needed. Lastly, I clicked on the astro noise reduction button to help reduce the noise in the sky.

In PSE 11, I first cloned out unwanted objects such as a line of light from a plane in the sky or a lightening bug flying through the image. Additional enhancements included contrast, saturation, brightness and levels layer masks brushed into certain areas of the image. The unsharp mask filter was used to sharpen the image after cropping and straightening once all the adjustments were done.

I took two different series of images to combine into star trails using StarStaX which lasted about 10 minutes between the first and last image took using the interval timer on the camera. The time between each shot was five seconds. It sure seems like a longer time when you are setting in the dark. Hopefully in the future, I’ll be able to do an image that is a few hours long which would allow the star trail to start on one side of the image and finish on the other side.

With these images complete, I have to say I agree with the Exsate Golden Hour app has the stars and Milky Way shine bright in these photographs and I’m very happy with how they turned out. The D750 continues to impress me with its ability to capture the scene.
