    The Rude Star Finder greatly facilitated the taking of late am and early pm twilight star sights before the stars were visible to the naked eye and  while the horizon was clear and distinct by considerably reducing the work of precomputing altitude and azimuth. With a little extra work the navigational planets could also be plotted on the disk and included in the precomputation. There was no need to visually identify the stars prior to observation.

    I Wws using my Rude Starfinder the other day which prompted some questions concerning the ingenious device.
    Does anyone know who invented it (Rude?) and when?
    Did it significantly change the way celestial was performed at sea?  Were navigators more inclined to observe morning sights vs. evening sights prior to the Rude Starfinder due to the fact that they could identify the constellations prior to morning twighlight?
    Thanks!
