Dear Users! The "Image of the Month" for February 2003 is now online at the Astrometrica web site, http://www.astrometrica.at. Click on the thumbnail image on...
I recently used Astrometrica to do astrometry/photometry reduction of some fields containing Galaxies (SN hunt) and found that it reported a Catalogued (GCS2.2...
David, I don't know your images, so it's difficult to say anything about it. Anyway, I wonder why a 13mag object would be missing in both the UCAC1 and the...
We have obtained high quality measures (astrometry/photometry) of asteroids with astrometrica and we have found the program very useful mainly due to the...
... Astrometrica performs simple aperture photometry. This is sufficient to measure the brightness of stellar sources (stars or asteroids) but it runs into...
Dear Freinds, I had a hard-dosk failure today, and I have lost some of the recent e-mails. If you have sent me an e-mail in the past two days and did not get...
Hi folks, I just had a fine example of how careful one should be when using track+stack on NEOCP one-nighters. We observed AF42940 with the 0.3-m on Mallorca...
It's nice the way to tell astrometrica what the coordinates of the center of the image are just by selecting the asteroid or comet name from the list. Most of...
... I forgot to mention that we are binning 2x2, so pixel scale is 3.72" for this setup. We try to limit the maximum exposure time to 2 pixel trailing....
Reindeer: When I have an unexpected object show up in a track and stack set I usually try to measure just same end of the trail in each stack, take the...
... Just wanted to note that, if the the object would be trailed on the single frames, you could re-stack the images with whatever motion you want, and you'll...
... Note that, while *your* images usually start with the name of the object, the file names of many of the other users probably don't. And if you use the...
I agree with Herbert completely. I use CCDSoft V5 for image acquisition and it can be configured to include the object name (sort of) in the filename. Most of...
... Yep, sure. It was already ~ 12' off and I saw on NEOCooP that 557 reported "no detection". As the 0.30-m at 620 has a 1k1k 24ym SITe-chip and thus ~ 32' x...
I have read in previous messages that Astrometrica can take information from the FITS header avoiding the step of selecting the object of interest in the...
I think that the keyword 'OBJECT' in the FITS header would be useful to fill automatically the object field in the "Coordinates" dialog during the Astrometric...
This seems reasonable enough. Some software (CCDSoft V5) writes, under some circumstances, the keywords OBJCTRA and OBJCTDEC and the values. There are many...
... I know it the other way round. OBJCTRA and OBJCTDEC give the approximate plate center and thus can be used directly by the astrometry software. OBJECT is...
... Unfortunately, these keywords are not standarized. There are a number of other keywords used by some software to specify the coordinates of the filed, and...
... be ... the "Coordinates" ... the ... Hello: I repectfully disagree in Reiner's opinions : Astrometrica makes astrometry very easy. Every program feature...
Herbert actually has an object name/designation search engine already in the program. I believe that while names change with time and/or are not really...
Fellow Astrometrica Users, I'd like to be able to reduce images at my telescope to check pointing. The full USNO A2 is a little large to install on my laptop...
... The fit with the filtered zone file had 188 ref >stars and gave the same positions within 0.01 m RA and 0.1" dec. ... Great Idea Dave! It looks like you...

David, I’m having trouble with your PERL script. I’m new to PERL, just got it today. I’m running ActivePerl 5.8. I would like to run this script. Could...
If you don't have room for the full A2 catalog on your laptop, there is an alternative. Use a PCMCIA IDE interface and strap on a supplemental drive. The...
1 CD would be fine. 10 is another matter. -John ... _________________________________________________________________ STOP MORE SPAM with the new MSN 8 and...
... Bob, Thanks for the suggestion! The entries are also sorted by RA so it might be feasible to do in one pass. I'll play with that - not much else for me to...
