Impressive shot, Tony!! Have you measured the limiting magnitude of the
image?

Best regards,
Arne

Hello,

     This galaxy in Pisces turned out to be a lot harder to image properly
than I thought ... turns out that you need enormous signal to noise to
record the faintest elements ... in the process a maze of faint galaxies
showed up in the background ... hard to say if some of these are galaxies or
faint stars ... but I'll bet a significant number are galaxies ... there
seem to be some groupings in the upper left part of the image. Five hours of
luminance with a 14.5" f/8 Cassegrain under cold and dark winter skies gets
you ...

     Have a good one,

          Tony
