If you encounter a timeout during download of USNO-B reference star data from the VizieR server, please change this line in the [Internet] section of the...
Thanks Herbert. I seem to remember you mentioning it is possible to configure Astrometrica to use a local copy of the USNO-B1.0 catalogue. Is that right or...
Hi, Herbert, In my case, the VizierMax was already to 9999, but after a "Ctrl-A" My first try ALWAYS fail during the file dowload, after about 80 to 84 Ko, and...
... I don't know where the "Ctrl-A" comes from, but the line should look like this - nothing more, nothing less: VizierMax=9999 ... It may appears strange, but...
Thank you Herbert for your answer, The "Ctrl-A" is the short sequence from Astrometry, Data Reduction.... Just for memory... LOL... Kindly, Hervé J ... De :...
Herbert, I have a request that is linked to this part of your software. I know that the data is put in a temporary file as you have explained but could you put...
Richard, I appreciate your suggestion, but it's not as easy as it seems to be at a first look. The problem is not storing the data in a non-temporary file, but...
... Forgot to mention that in my previous message: If you still encounter the problem after checking the "VizierMax" setting (I rarely, if ever, have that...
O.K. Herbert, I guessed this would be quite a complex situation. Here's another question, which isn't aimed at modifying the software: What is the name of the...
... The file name is 'StarCat.tmp', and it is located in the systems temp-directory. (Open a DOS box and enterthe command 'cd %temp%' to see where this is...
On the buffering issue. I had a period where I had trouble getting a download of B-1. To get around the buffer issue, I deliberately changed the coordinates...
Hello all: I am a new member who is beginning a program observing double stars. I downloaded and am now evaluating Astrometrica. I am working with a robotic...
Ed, The rotation is relative to celestial north, and does not change unless you rotate the camera. Since you are using a remote 'scope, I am assuming it is...
I note your reference to 'doubles' - so I presume you are interested in measuring the PA and separation of the components. In my mind, this leads to the...
Assuming that you are using a polar mounted telescope (not az/alt mount) that has a good polar alignment, then -8.41 degrees is your camera rotation from...
Bert, Jim and Dave: Many thanks for your replies! First background, then an additional question. I am working remotely with the RAS Observatory in New Mexico....
Ed, ... Additionally to what the previous posters said, it should be noted that in real life you *always* have a different field rotation from image to image,...
Just adding to Reiner's comments about different PA's for the camera. On images I took tonite, the angle is computed as: -2.42, -2.48, -2.56, -2.71, -2.74,...
... I agree. In addition to what has already been said, the rotation angle is calculated by using just the linear terms of the solution and it is, in fact,...
Ed, are you trying to observe very close doubles. If you are looking at doubles separated by more than about 6 or 7 arcseconds, you need to increase your...
... Also note that if the angle is measured relative to the J2000.0 pole, the angle at the center of the chip to the pole will vary depending on where in the...

Not that this matters too much but I think Ed mentioned ST8 camera and it has much smaller FOV than 30'x30' at f/9.1. I work at f/6.3, effective focal length...
Wow, this is a great group. Thanks to Robert, Ladislav, Jim. Herbert, Reiner, Dave Bert and everyone else who I might have missed in answering my questions! It...
