I've been curious about something: does chromatic aberration follow linear superposition? In other words,
if I try something like wide-field astrophotography with my Pronto, will longer exposures (and hence
brighter, final star images) show false color on sources that showed little or none visually? I realize
that bright visual images (such as planets) will, of course, show false color on film or CCD- but I'm curious about the integration over time of dimmer sources.
By the way, I just received my oberwerk 15x70 binocs- and am knocked out by their performance, especially
for $150!! I wish I had bought them long ago.
best regards,
bill
