The North America Nebula has been on my To-Photograph list for a while. I had made one quick attempt previously to see whether I could actually resolve it with my Nikon 85mm f/1.8 lens. That was successful so I was ready to try again when the situation permitted.
I finally found the time, the right weather, and the right conditions. I shot a sequence of seven, 120-second exposures.
There are many star-stacking software packages available and I’ve often used DeepSkyStacker (DSS). More recently I’ve been testing StarrySkyStacker (a macOS-only app). The results have been pretty good.
The stacking complete, it was time to work on the histogram. Again, there are many histogram stretching packages. I’ve been evaluatingĀ rnc-color-stretch, available from Clarkvision.com. rnc-color-stretch is a set of scripts that calls the davinci application (not to be confused with the DaVinci Resolve video editing software).
The result is shown above. My next attempt at shooting this Deep-Sky Object (DSO) will be with my recently acquired Nikkor 180mm f/2.8 AIS manual focus lens.
