Hello everyone, I've been processing some images from nearly two years ago, and Astrometrica doesn't seem to recognize two comets (21P and 60P) although they...

If the comets aren't included in the comet.dat file downloaded from the MPC, then Astrometrica won't find them. That file is held in the Orbits subdirectory of...
... Sure, they're not in the current COMET.dat Regards, Juan Hello everyone, I've been processing some images from nearly two years ago, and Astrometrica...
... Yes, more or less. Because the comets are no longer currently visible, the elements are removed from MPC's COMET.DAT file, and in turn, Astrometrica, which...
Hi Herbert, Dave and Juan, Thanks for your comments. Of course, Herbert, I'll enter them manually. I forgot about that. Best wishes, John, Dr. John McCue....

Hi, I'm new to this group and I searched the archives before posing this question, so I hope I didn't miss the answer in my search. I'm wondering if...
... No, that's not possible. As you porbably know, there are some very successful solutions out there using the astrometric engine of PinPoint, and possibly...
Hi, Did you know this software : http://www.autoitscript.com/ ? Because with this i think you can create an automatic reduction after you can make a program...
Just a word from a 'satisfied customer' of Astrometrica for more than a decade. Plate solution is a bit tricky process and using Astrometrica and, possibly,...
Hi I am new to the list - and to using Astrometrica. I downloaded a new copy of the installation file and installed the software - having removed the old copy...
Donna, please give me a few hours time. I am currently at work in the office. I will send you the solution in a private Message when I return home later today....
Hello, this is my first post on this group, so I send a virtual strong handshake to all. When I blink images not perfectly centered on the same field of view ...
Dear Emiliano, you do nothing wrong, it is a wanted feature. Just imagine you blink three images, which partially overlap. Now there is a new minor planet in a...
Hi Emiliano, try to increase the Alignment area and/or n° of stars in the Program Menu of the Settings of Astrometrica. Regards, Luca Buzzi # 204 ... Da:...
Hi Gert, to know your real focal lenght, if you have'nt just done, let a try to this: get one image of a known angular separation (e.g. the angular separation...
Hi Luca, I think that the problem that was talking Emiliano it is not about a wrong alignement during blinking. He was just talking about the black stripes...
I would like to suggest that if the black areas are causing problems with the blinking, shrink the window and use the slider bars so that only the common area...
Dear Herbert, my opinion is that when you get the fields with single exposures (not a set of images to stack) three images are the minimum you must have to...
Hi Fabrizio, yes, I've better understood Emiliano's answer only when Herbert replied... ... Strange that I've not understood a question from an Italian guy...
Dear all - I have successfully completed the astrometry on a bunch of images using the USNO B1.0 catalogue. However, I am now trying to do the same thing on...
... You can't do that, but you can download a portion from a USNO server (http://www.nofs.navy.mil/data/FchPix/), store it in a file, and use this. Or you can...
Dear Herbert - ... Yep - this is exactly what I was trying to do. Could you please send me more information on how to achieve this, including which checkboxes...
Lisa, If you would be interested in obtaining the B1.0 catalogue on hard disk drive, drop me a mail to adsl7117 at tsn.cc Vincent ... From: lmgermany To:...
Before getting USNO-B1 on a hard drive, be aware of the USNO NOMAD catalogue. Hopefully Herbert will enable NOMAD access in Astrometrica in the near future....
Regarding USNO-B 1.0 and NOMAD, there was an interesting discussion at the German meeting of asteroid observers some weeks ago in Berlin. L. D. Schmadel from...
Hi Herbert, Just the curiosity. Considering that Nomad is a hierarchical merging of catalogs and that those catalogs seems to have systematic errors... Why...
I have certainly noticed relatively fixed offsets at times between B1 and UCAC2. But it is not a trivial exercise to compute that offset on a routine basis....
On the issue of dealing with systematic errors. The NOMAD catalogue is a mere compilation of catalogues. Any and all 'errors' in the individual catalogues are...
Herald, Who was it that asked for your opinion? Vincent ... From: Dave Herald To: Astrometrica@yahoogroups.com Sent: Monday, August 20, 2007 11:57 AM Subject:...
... Lutz Schmadel said that the systematic errors probably are due to the proper motion data. The proper motions are not in a fixed reference frame, but are...
