Originally posted by UncleVanya Can you expand on how this shot is achieved? Obviously the starts move during the capture of so many images, what is the process to stack and realign them? How did the reflection prove difficult?
That's a huge undertaking to expand on at the moment for me. Look up Astrophotography star trackers for milky way and there are a lot of articles on it. For stacking the tracked star shots I use PixInsight.
The reflection was difficult because while star reflections were sharp in the longer tracked exposures, stacking to help reduce noise and bring out detail didn't work. Obviously the untracked 4 minute exposures had a lot of trailing in them. The reflections of the stars were glorious on the perfectly still water. If I had done the work to capture them properly, I wouldn't have had such a hard time and the image would be a better rendition of what the camera saw.
