I shot this tonight from my driveway. One still frame grabbed from a 30-second video with the Pentax K-30 DSLR in video mode. High cirrus, some thin ground fog forming, and high-altitude turbulence. It's a good thing Venus is so close and huge right now. The smallest bino or finderscope will reveal the crescent.

Thanks, Joe. I spent most of the afternoon watching Venus duck in-and-out of clouds and wasn't even sure that I'd be setting up for the shot, but with the sun just about to set, a hole opened-up right where Venus was, and I rushed to get it all set-up in the driveway. I first shot some stills using direct-objective, but the image was too small, so I quickly switched over to eyepiece projection and shot in video mode, knowing that I'd get a lot more frames in the same amount of time. Even so, the seeing was so poor that most of the video frames were throw-aways. I think it's true that video is the only way to shoot lunar, solar, and planetary. The target is bright enough to pull it off, and you get thousands of frames to choose from and work with. The lower native resolution is more than made-up for by frame stacking and super-sharp individual frames. If the weather cooperates, I'm going to shoot Venus again in a few days, and on Jan. 11th during Inferior Conjunction, when it will be only 5-degrees north of the sun. That's as large as it will appear until 2022, 62 arc-seconds in diameter- that's about 1/30 the apparent diameter of the moon! Right now it's almost that large, with the crescent easily visible with the slightest optical aid. A pocket bino, golf scope, or opera glasses will clearly show the crescent. We are in the last few days of Venus as an evening object, until next October. By August, Venus' disk will only be 10 arc-seconds in diameter, one-sixth the apparent size that it is now. It's sobering when you realize that Venus is the size of earth, and so close right now that humans with vision in the top 1% can just make out the crescent with no optical aid whatsoever, in good seeing conditions. You can easily see it in broad daylight if you know where to look. On Mon, Dec 30, 2013 at 7:16 PM, Joe Bauman <josephmbauman@yahoo.com> wrote:

You had a lot better luck than the rest of the gang did with the telescope in Hawaii -- the relative humidity was too high! Good luck on more pics. That one looks like an entry for the astrophoto contest. On Monday, December 30, 2013 11:05 PM, Chuck Hards <chuck.hards@gmail.com> wrote: Thanks, Joe.

Yep. Looking forward to seeing what can be done with them.

First, sorry to all for forgetting to change the subject when I started discussing the imaging session on Chuck's Venus thread. Kudos to Chuck, BTW, for a great image. But now that I've changed the subject line, as to tonight's imaging session, despite the conditions improving on Maui the scope there never did come on line. So JD programmed the 2m to take images automatically at the next opportunity. He then switched us to the 1m in Chile which we initially thought we could not get time on. But a chunk of time opened and the images started coming in. At that point a number of folks headed for ATS. SLAS ended up getting kicked off by a higher priority project but enough data were received to work with and Tyler said the data received were superb. The plan is for JD to send Rodger the URL to all of the data once it's all collected. Rodger will then publish the URL so that anyone who cares to can download and process the images. Tyler is then going to work his magic on the data at next month's SLAS meeting. BTW, I think tonight's experience might show why so few really get into this stuff. It's really is a complex, tedious and some might even say boring process. But the results, for those who really stick with it can be stunning.
