<br />Here's the latest image from the Bradford. at 11 27 9.60 RA
-9 12 36 Decl.

(edited) I took a look at the faq page at the Bradford and it says that sometimes the image is upside down because of the mounting. The image is flipped horizontally by default, So if the stars are upside down, then one rotates the image rather than flipping it vertical. So I changed the image to a rotated 180 degree image, rather than the flipped one I'd put up at first.

Thanks! So far, though, even by mentally rotating it, I can't correlate this photo with the same-size (13 or 14' square) Aladin Optical Red image ostensibly centered at those coordinates. Earlier today I didn't have very much trouble mentally rotating another photo someone sent me. I've tried two or three times and also sent an email to the webmaster, but I can't get any response from Bradford about getting an authorization to submit jobs myself.

Hi Joe, why don't you just join again?

Now, on the question of those images from the Bradford. in one place it says that the galaxy camera take images half the size of the full moon but in the hardware section of information, it says 24 arc minutes per side. I think that the bright star, right of centre, lower quadrant, is the star 14 epsilon Crater. So, 24' per side looks right.

I sent them an e mai as well, about the rotation of images. In computer animation there is a problem with cameras. These virtual cameras take the y axis as "up." If they are given a target to follow and the target passes over the top of them, then the y axis drops down to the zero zx plain. When that happens, the y axis can flip round. It's called gimbal lock. It can be fixed by giving the camera a second target that the camera has to try and follow at the same time. It's a software problem that perhaps they haven't sussed out yet.

Anyway, I've put that job back up and hope they take only a few days to do it.

Your fits viewer should have a stack command somewhere. Open two fits files and then stack them. They will be scaled properly, you then have to move one to line up the stars. There should also be a command to animate the stack, which will show any blinking of stars, which indictates movement.

The viewer i got was MicroObservatoryImageMac2.0 which can be got for a pc.

Just had a hunt for a fit viewer that will open the 3d fit files from Bradford. Found this one that's available for pc's as well as macs. It will take a while to get the hang of it, as the docs aren't that good but with a little bit play I got a pretty good image up.

I did a check with starry sky back yard, and one can see that there's a hexagon of stars, with 14 epsilon Crater bottom right corner , that fits the Bradford image. No need to rotate it at all. Now, is our brown dwarf still about a degree up and a little to the right of 14 eps?

"Barbarossa's estimated apparent diameter is 0.9". Barbarossa's estimated retrograde motion is 0.7"/hr."

Not with you there Joe, I get about 0.05"/hr. A good few months to get a decent blink going but we should be able to get a blink for its planets' orbits

Nem 5 is up now on the Bradford. Same coordinates as the last one but not as good an image as there's some wash from the moon in the image. I think as the Bradford does jobs quite quickly, once the weather improves, I'lll wait a few weeks before putting the job up again.

[] oops, I seem to have transposed the minutes and seconds of nem 5. No great problem [] practice in moving the images over eah other.

Well, just goes to prove that even we omnipotent folk can make mistakes. I once created a stone that I couldn't lift [][8D]

That link to the fits file viewer. I just found out it links to nasa's skyview database. A few seconds to download files.

Here's a few images from the sky survey of the last coordinates given. I didn't alter the last two as i don't know how a clean up would effect data reading.



Close up of the first image. White dot in centre, with a green dot above and to the left. If this is a star, then our mystery planet is almost on top of it. Could be hard to spot but that might help with our blink over a month or so.
