For my astrophotography tests I set NR to Low. There is also Noise Reduction: High, Normal (default), and Low. White Balance can be adjusted, including setting a specific color temperature.
This obviously limits the camera's ability to capture faint objects. At ISO 1600 it is 1 second, with ISO 800 it is 2 seconds, ISO 400 is 4 seconds, ISO 200 8 seconds, and ISO 100 15 seconds. With ISO 3200 or 6400, the slowest shutter speed is 1/2 second. Even in manual exposure mode, the Exposure Value (shutter speed + ISO) is fixed. However, there is a distinct drawback with the P900 for long exposure astrophotography: there really is not a LONG exposure capability. With my DSLRs I most frequently use M for astrophotography.
Review - Astrophotography with Nikon Coolpix P900, page 2Īs with my Nikon DSLRs, the P900 has P, S, A, and M modes for Programmed auto, Shutter-priority auto, Aperture-priority auto, and Manual exposures.
