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:
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.

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.
