Hi, How does Astrometrica estimate the SNR value which is displayed when you click on an object and which is recorded in the ADES astrometry and photometry reports? I get some very strange results whe

I read the other thread I found regarding this issue. I can get Astrometrica to work on my office computer ( not the optimal time to be working on a hobby) I can not get it to work on the home compute

Hi All, I have been observing 3-4 asteroids a night with 3 observations of each asteroid with a span of around an hour between each asteroid observation per asteroid. I have been sending the reports b

Hi All, I read somewhere that the MPC center publishes observations by observatory or observatory code. Does anyone no if this is true and if so where to find these reports. Thanks, Bill

MPEC statistics, but not on the MPC site. Lots of good lists... http://mpec.jostjahn.de/stations.html

I am an iTelescope.net user and frequently use Track and Stack to measure faint asteroids. I keep running across a problem of the order of image stacking. It seems to be related to iTelescope file nam

Hi all! Is there any way to change the scale of an image in astrometrica?

Dear all, what can I do if the reference star match appears like this? https://www.astrogeo.va.it/astronomia/Astrometrica.jpg Thank you, Luca # 204

Hi all! Is there any way to align the images in astrometrica with the WCS coordinates in the header? Do I need to align the images to perform astrometry or can it be done without it?

Hi all, I have been trying to find MPS documents (MPS 1200872) on the minor planet center with no luck. Does any one know if the documents are available for viewing like the MPEC's and how do I find t

Hi all, Whenever I use Known Object Overlay tab and then I click on the little red square I get the following error message: "Access violation at address 77B29E6B in module 'ntdll.dll'. Write of addre

Hello, the error message "No Reference Star Records read" usually appears when Astrometrica tries to download reference star data form the Vizier data service, and the server does not respond in time.

Hello, can anybody tell me, where I can download Astrometrica Vers. 4.12.0.xxx with ADES support? The link in a mail from July 2018 doesn't work anymore. And on the homepage only Vers. 4.11.1.442 is m

Hi all, I am curious what others do with the images once the measurements are sent in to the minor planet center. I am trying to decided if I should delete them or not. Right now my feeling is to dele

Hi All,

Hi I cannot get astrometrica to show comet 115P. I have updated the MPCORB.DAT but still nothing. Astrometrica shows the asteroids but not that comet. Do I miss something here? Louw

Hello, We have installed Astrometrica on our computers and have worked out all the Practice Datasets available. We have been practicing for last few weeks, checking out different functionalities of th

I am getting errors on updating data files for minor planet files etc...and cannot update. Thinking of a glitch I have reloaded the astrometrica several times to no avail. Any ideas ?

Hi When you measure an asteroid what should the minimum SNR be for MPC to accept the data. Does the MPC has a minimum value? Thanks. Louw

can someone explain what is wrong, i can no longer get the astrometry to complete, i've tried numerous images that have worked ok in the past but all are failing with this error message. Thanks in adv
