Startrails from Gangtok, India. My first successful Star Trail image. Nikon D850, Tamron 15-30 mm F-2.8 G2 Lens, F/2.8.
The exposure was for 20 seconds with at ISO-1250, and 5 sec interval for the next shot. Generally people go with extended exposure time, but I planned for less exposure time and low ISO because the lens had a wide aperture of f/2.8 and the dynamic range of Nikon D850 is great to get such images in the low light conditions. There were about 100 images which made this picture. Each image is about 55-60 MB in size. All shot in RAW format. It was about 6 GB of data to make One image of star trail. The shooting of images did go for nearly 1.15 hrs. Later the images were processed to JPEG format in View NX-i. I was super excited to see the trails, but StarStax crashed all the time i tried to stack the images. Later i figured out, since the image size of the individual JPEG images was huge, the Star Stax used to get crashed. So i found out a way to somehow stack all the images in Photoshop CS6. And further processed in Adobe Lightroom to extract most of the sky and colors. Everything happened in one night which included taking images and processing. By 5:00 AM in the morning, i had the first successful image of the Star Trail. This final image is 65MB in size.
Post processing plays plays a major role in making your picture and this comes with practice. You should try with all of these software and enhance the creativity in you.
