Just did some quick calculations, the difference between the 1600 and the 694 (674 as well as it is just a smaller version) with 3nm narrowband filters is negligible. The 1600 has lower read noise at gain 0 (3.6e- vs the 4.8e- I get) but also has smaller pixels (3.8 vs 4.54 microns) and a lower QE. Both cameras will require the same amount of time to reach read noise limited under the same situations, with the 1600 at gain 0.
