The Veil Nebula in Cygnus

It
            has been over 20 years since I have shot the Veil Nebula in its
            entirety, harking back to a pair of stacked 8 minute exposures
            on PPF 400 film taken with our 8 inch Schmidt Camera from Happy
            Jack (See Here). This new image of the
            Veil with an 80mm refractor at the same location and using a
            cooled OSC CMOS imager superceeds the old shot in every way.
            Here, the exposure - or today refered to as the "integration
            time" is 24 shots 5mins each stacked for a total of 2 hours.
            Surprising to me is how separated the OIII is from the Halpha.
            It is hard to imagine how a centralized exposion of such magnitude
            can eventually cause such a differentiation of the filamentary
            composition. Shown here are both shots - The old Schmidt shot
            on film, and the new digital shot on CMOS. Tech data: Stellarvue
