Hello All, I am new to Astrometrica and new to the list. I downloaded the evaluation and so far, I really like it. One question I do have is about switching...
Hi Brian, You don't need to exit and restart Astrometrica to use a new/updated config file. Ideally you will save 2 configs - one for the UCAC and one for the...
... Any change in the settings is valid as soon as you press OK and leave the settings menue. No need to close and restart Astrometrica! I use different...
Hi Reiner, Thanks very much for that information! For some reason, I got the impression working in it earlier that the changes to the settings did not come...
Hi David, Good to know you are here too. Hope things have been going well! You and Reiner have certainly given me the information I was looking for. I was...
Hello John! Good to hear from you! I can't say I have a SF16 any longer since most of it has been replaced including a Royce mirror. Here is the current...
Hi folks, as many of you have asked me privately about Herbert, I thought I give you an update here on-list. Any personal replies please to Herbert privately. ...
Hi folks, just wanted to say "Hello" again. Reiner already informed you about my status after the surgery, so there is not much left to say for me. :-) I will...
Great news! Good to know you are back. LN from Florida ... From: Herbert Raab [mailto:herbert.raab@...] Sent: Monday, September 06, 2004 5:03 PM To:...
... I just wanted to thank Rolf and others that responded to my question (see subject). I received responses both through the group, and privately from group...
Hi list I wonder if someone can help! Ive been using an older version of Astrometrica for a few years and recently upgraded to v 4.3.3.532 Since then I cannot...
Matt: As a first thought check pixel sizes and binning, at one point in time Herbert changed astrometrica to read the binning keywords in the header and using...
Problem(and image)solved! Many thanks Dave. As you guessed I was specifying my pixel size as 26 instead of 13 micron in 2x binning mode, not realising that ...
I am sorry for the delay, but I finally managed to bring the "Image of the Month" for September 2004 now. To see it, please visit the Astrometrica web site,...
... Which is the reason why the spacecraft does *not* move in the same direction as the stars are trailed? After all the images seem to be stacked on its...
... I *think* (though I don't *know*) that the spacecraft moved in a slightly different direction than the ephemeris predicted, due to the shorter than planned...
... The length of trailing of the asteroid on each stack should be the same as the offset between two consecutive stacks prependicular to the direction of...
Sorry folks, I got a little behind in my email reading! First, I think the spacecraft is not exactly following the star alignment trails, not because the...
... North does not have to be at top. Astrometrica solved each frame and thus does know the rotation angle and corrects for all this when stacking. What it...
Well, the stacks were made with our own software (which does not solve for the frame, and assumes North is exactly "up"), and you really do need to have the...
I'm pretty sure that the reason Messenger's motion is inclined to the trailed stars is that the orbit of Messenger is inclined to the ecliptic. I've been ...

I think you're missing the point. The reason the stars are trailed is because several short exposures were stacked with a deliberate offset, intended to be in...
John, You're right, the spacecraft's motion should match the star trails. End of a long day -- brain fade was setting in. Paul...

I was listening to the thread on Messenger and forwarded part of this message to Dr David Dunham ( the man responsible for putting Messenger on target to...
I've thought some more about this and have come up with two possible reasons for the asteroid's motion to depart from that of the trailed stars. First of all,...

Another long day? You're trying way too hard to eplain a simple problem. The .gif consists of five frames, each of which is a stack (with offset) of four...
The "Image of the Month" for October 2004 is now online at the Astrometrica web site, http://www.astrometrica.at. Click on the thumbnail image on the menu bar...
