Igor, If you look at the pictures in fluidr: http://www.fluidr.com/photos/ellarsee/sets/72157639424720424/ I have both a 13 second and 20 second version of the shot, also one shot six minutes earlier with Venus earlier in the sky. 1) While Venus does have planetary velocity around the Sun showing apparent motion compared to the stars, I don't think that it would be visible in a 20 second, or even a 20 minute exposure. The moon, yes, Venus no. 2) Remember the photos that Bob posted a couple of days ago with the Moon right on the horizon? Remember the distortion of the Moon at that point? I suspect that is the same thing going on, in the same way that the Sun, the Moon and Venus all look orange when right on the horizon. 3) I'm not sure quite how chroma distortion works and whether it would affect a bright spot rather than something more moderately exposed, but could that be affecting the shape? > > Cheers, > > Igor > > > > On Wed, Jan 22, 2014 at 8:59 PM, Larry Colen <lrc at red4est.com> wrote: > > I tried sending this out yesterday, but it never showed up > > in my mailbox. > > > > None of this series had originally been posted in my last batch of > > Big Sur photos, but Candice was asking about them, so I cleaned up > > a few and posted them. > > > > http://www.flickr.com/photos/ellarsee/12081256754/in/set-72157639424720424/ > > > > C&C always welcome > > > > -- > PDML Pentax-Discuss Mail List > PDML@pdml.net > http://pdml.net/mailman/listinfo/pdml_pdml.net > to UNSUBSCRIBE from the PDML, please visit the link directly above and follow > the directions. -- Larry Colen l...@red4est.com http://red4est.com/lrc -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
