For the first time since I returned from Germany, the sky was predicted to be clear overnight. I have been wanting to try the 8-15 mm fisheye lens (that I borrowed from my brother) for doing some star trail images, and night sky time-lapse videos. I did have an issue with condensation on the very wide lens in the early morning hours. I have had the condensation problem on other wide lenses (14 mm, 14-24 mm) in the past, and may need to fashion a small tape heater on the lens.
Star trails over New Jersey. Composite of images taken with a Nikon D850 camera and 8-15 mm fisheye lens (ISO 100, 8 mm, f/4, 30 sec). Raw images processed with Capture One Pro, and the composite generated using Photoshop CC (statistics, maximum). Individual images from the slide show can be viewed here.
Moon Sequence. In camera composite of moon images taken with a Nikon D4 camera and 600 mm f/4 VR lens (ISO 100, 600 mm, f/16, 1/60 sec). Images taken every 2 minutes. Raw image processed with Capture One Pro 8, Focus Magic, and Photoshop CC.
Star Trails. Following Hurricane Irene, we had a couple of days and nights with very clear skies. You could even see the Milky Way (although a lot dimmer than in locations with less light pollution). I set up a Nikon D3s camera with a 16 mm f/2.8 fisheye lens to do star trails last night. The settings on the camera were manual (ISO 400, 16 mm, f/4, bulb). The exposure time was controlled with a MC-36 itervelometer (delay 5 sec, long 59 sec, interval 1 sec, N —). In camera long exposure noise reduction was turned off. The 1 second interval is required to allow the data to get transferred from the camera to the card, and effectively have one image taken every 60 seconds (1 minute). The MC-36 is required for exposures longer than 30 seconds. After the images were transferred to the computer, the RAW images were processed with Lightroom, and converted to JPG. The JPG images were then processed using Startrails.exe program to make composites. The following images show a single exposure, then startrail composites of 2 minutes, 5 minutes, 15 minutes, 30 minutes, 60 minutes, 120 minutes, and 300 minutes. Some high level clouds came in for the 300 minute (5 hour) image.
