A reminder that Ceres and Vesta and converging. Tonight about 26' apart and getting closer. A stereo pair shot tonight (2014 JUN 30) at 0419 and 0459 UT: http://users.wirelessbeehive.com/~paw/temp/cv2014jun30.jpg patrick
Patrick, can you repost the pair, perhaps with a marker showing Ceres and Vesta? I'm not seeing anything that's jumping out in 3D, or even moving between the two frames. Thanks! On Sun, Jun 29, 2014 at 11:17 PM, Wiggins Patrick <paw@getbeehive.net> wrote:

Patrick, Chuck, I agree with Chuck, the two images are nearly identical as far as I can tell when viewing them as a stereo pair. At the very most, I perceive the left most bright object is behind the star field indicating the images are left-right reversed for normal cross-eyed viewing. Maybe a longer time between frames and proper orientation would show positions of these two objects nearer than the background star field as we would expect.

Hi, I'd go longer between exposures if I could but my horizon to the south is poor so I've only got about 2 hours when the pair are where I can get at them. Add to that it not getting to astronomical dark until the pair are half way through the window and I've got under an hour to work with. I deleted last night's images and then got two more shots tonight. 30 minutes apart. I've reversed them in the image so both Vesta and Ceres appear above the star field. Vesta is the brightest object on the left, just above center while Ceres is the brightest object on the right and just below center. http://users.wirelessbeehive.com/~paw/temp/cv2014jul01.jpg I think these will be my final attempt at stereo. From here one I'm just going to try for one good shot each night as the two draw closer. I hope to spot the pair visually during Saturday night's star party at SPOC. patrick On 30 Jun 2014, at 07:59, Ed <utnatsedj1@xmission.com> wrote:

Hi Patrick, Sorry, I had no idea of the directional limitations and time constraints you were working under, but the results this time where great. Clearly Vesta and Ceres are way closer than the stars. I do enjoy the astronomical and terrestrial photographs you share with us. Good job well done.

Thanks Patrick. Now I know which dots are stars and which are dirt. These two objects just aren't good subjects for stereo pairs. Comets and the moon, something that subtends a fair angle on the sky, seem to be the best objects for stereo work. On the other hand, they are great objects for detecting motion with a blink comparator, IMO. On Tue, Jul 1, 2014 at 1:34 AM, Wiggins Patrick <paw@getbeehive.net> wrote:
