Hi Gert, I took the liberty of having a look at your image I could not solve your file automatically, nor in MaximDl (pinpoint) nor in Teleauto. I've done a...
Helo All, Special THANK YOU to Gerald McKeegan for resolving the issue. Together with him I also learned how to fix Zonealarm7 to allow astrometric to function...
... I tried your image to fix this. As it turned out, it was not a problem with the 32 bit format. The problem was that the FITS header of your original image...

Hi to all! I've had a Problem with the Vizier Server => Minor Planet and Cambridge UK. I have the UCAC at my lokal PC and Laptop. But sometimes I need the USNO...
For the last several months I've been having an occasional problem with track and stack, where I have two or more images that I can solve individually, but...
... This would indicate that Astrometrica can't align the images properly. If my assumption is correct, then the images also would not align if you try to...
... It blinks them. It was a windy night so there were some guiding issues with the second image (brighter stars show a faint second image), so the alignment...
John, one more setting you can check is the magnitude range for the reference stars ("Upper Limit" and "Lower Limit" for the Star Catalogue on the [Program]...
I checked and the saturated stars start at about magnitude 13.5, so I set the upper limit to 14. I still get the same behavior. If the # of alignment stars...
John, please pack a set of two images that won'rt align, together with the configurations file you use, in a ZIP file and put it on some server for me to down-...
John, I downloaded the files, gave it a quick try, and here is what I found: I first tried to solve the two images together (not stacked, but as two seperate...
John, I took a look at these files and here is what I found: 1. Changed the upper magnitude limit for the Star Catalog to 8.0 2. Change the number of alignment...
... Interesting- that may well explain why I hadn't run into this before. Previously I was using a different camera, and when I first set Astrometrica up, I...
... Also, why (when the position angle and focal length are set more accurately in the settings) does the auto match fail, but the manual match is accepted,...
... Usually, it is not. I think it is more critical in this case, with so many stars appearing double in one of the two images, which possibly confuses the...
Dear fellow observers, I want to bring to your attention a workshop on astrometry and photometry which will take place during the fisrt week of September (that...
Hello, It is a great notice for me the confirmation of your lecture in the workshop. I am Canarian astronomer and I live in Tenerife (where is placed the...
My flying fingers got the best of me when I was trying to update Astrometrica. I wound up with the updated program installed on my desk top instead of the...
... The update is simply a ZIP file that includes all updated files. You simply need to unzip that file in the same folder where the previous version of...
Hello All, What differential value in arcsec could be considered as correct for dRA, dDe parameters after doing the data reduction ? Is any rule from MPC about...
... Assuming that dRA and dDe are the mean residuals of the reference stars, then the value should be around 0.2" for the USNO-B and about 0.1" or better for...
Hello Joan, There is not a precise value for the dRA and dDEC, With USNOA2.0 -> 0,2-0,3 is a common value. Something less with ucac usually... More important...
Hi all, I have two smalls (and may be silly...) questions : As Astrometrica is a wonderful soft for astrometry, can i use it for photometry ? If so, what...
Astrometrica, as the name suggests, is an astrometric program. There are several photometric programs, I started to do some photometry using Canopus software...
Astrometrica isn't really designed for that. It will report magnitudes, but don't expect it to be accurate enough for any type of precise photometry. -John...
