Hi all,



I had the great pleasure of witnessing the transit of Venus with my friend Dave Jurasevich from Mount Wilson Observatory. George Whitney, Kirk Rogers, Mike Long and I were positioned in and around Dave's dome with a clear view of the sun from beginning of transit to almost sunset. Here are a few images I've completed so far. The seeing, unfortunately, was quite turbulent most of the afternoon... but I am not inclined to quibble with the gift of being able to experience this rare spectacle twice in my lifetime.

Alan,



Your first result below captures the Venus atmosphere and which is a

neat feat. If only you had greater focal length available. ;-)

I knew it would be just a matter of time before you would totally embarrass

us mere mortals :(



Congrats on some really great images!

Thanks Pete, Chris, Roland and Anthony. I spent a couple of restful days in Santa Monica after Mount Wilson, enjoying everyone else's photos of the transit.



My memory of the improvement in seeing as the afternoon progressed turned out to be sweeter than the reality. The data was much more difficult to untangle than I anticipated. Dave, Mike and George were using bigger aperture scopes and might disagree, but I don't think the resolution of a 90mm aperture was tested. Despite the turbulence, the atmosphere of Venus was quite evident in the videos captured during the period between first and second contact. I haven't quite figured out how to present this data, but here is a look at a composite of two exposures taken during ingress. The sliver of atmosphere needed a big exposure push to be seen clearly:

As luck would have it, I returned home on Saturday to some of the best seeing I've experienced in years in the air above my backyard. I have a nice a pile of solar and saturn data to explore.



cheers,

Alan

Most excellent!. Does it need a Starburst label?.

Those are stunning pictures Alan! Well done! I was wondering where your images where, I was afraid you got clouded out....congrats!

Alan,



Stunning images as usual! I especially like the one where you were able to capture hints of the elusive atmosphere of Venus slightly past 3rd (?) contact. Perhaps you should review your other images and see if you have more revealing images of the aereola.



Best wishes,



John

WOW! Outstanding, Alan. One of the best I've seen of this event. I would definitely frame and hang in my living-room the B&W one. Beautiful!

Hi John,



The seeing is very poor at this point in the transit - I haven't had much success mining the data. I will go back and see if there is an approach that gives a different result.



Ignacio, Percy. thanks very much for your notes! I am working on a suite of full disk sun prints that hopefully show the sun in a different light. More on that a little later.



all the best,

Alan

Here is a small cropped section of video constructed from 250 of the best frames between first and second contact. Even with the nasty artifacts of youtube compression, you can see the outline at the edge of Venus.
