Hi Ken and Pete,
Is this Zuiko 135 mm lens special good for astrophoto? I read about it at internet, but didn't find any about to use it for astrophoto. Looks nice anyway.
Pete your photo of Southern Cross is awesome.
By the way, I never put any protection filter on the lens when doing astrophtography nowadays. It just cause me problems, dew, reflexions etc. But later if I take away the filters in my camera I of course have to implement some filter to limit the wavelength spectrum.
Has anyone tried to divide a color photo in two steps to get the best resolution when not APO lens. One focus at blue and green and another for the red?
/Lars
