Re: [APML] California Nebula

Hi Matt:
Another gorgeous shot! This is a single exposure, right?  Should we consider
bigsmooth as a possible substitute for stacking---at least for grain
reduction? Your LVM---darkness is also impressive---can you see mag 6.7
stars there or is that not what your note means? (I know that people have
claimed to be able to see dimmer than 7 on rare occasions in exotic places.)
Not having seen many other sites, I don't know how to judge my own site vs
my visual acuity. I have difficulty seeing 5.5 with averted vision at my
site after lengthy adaptation, but that may be my 69-year-old eyes.
