I resized an original fit image to a smaller image, then astrometrica can not load it (fake death state) though the original fit image can be loaded easily. ...
The problem has partly been handled now, I set the reduced picture as uncompressed in maxim,and astrometrica can load it now. However, the reduction doesn't...
... Could you also provide the configurations file you use, so we would have some idead abou the pixel size, focal length, and the other settings you use. ...
Hello, Some may recall that I get about 1,000 images a night. And I need to separate them into sets of 20 to 60, then divide the set into three, then stack...
Would a solution requiring only a linux box be acceptable? The benefit would be that no third-party _commercial_ software is needed. Regards, Hannes...
Well, sure. I need Linux for another project I am starting. I was really trying to postpone any hardware purchases. No third party commercial software solves...
Hi there, I have dabbled with stack and track for a while now. I have a few questions I can't figure out at the moment. The software I use quotes the start...

... That is correct. Astrometrica takes the timestamp from the FITS image header. If it's configured to interprete this as the start of the exposure, it adds...
There is the fact that 90% of the world's computers run on Windows -- which means a Linux-specific solution is relevant only to a minority of PC users. One...
For many years, you have had always an excellent point. Just out of curiosity (it has ABSOLUTELY nothing to do with Astrometrica), is there some comprehensible...
Thanks. I'll have to read your message and follow the links carefully. Apologies to 'real' Astronomica users. LN ... From: Astrometrica@yahoogroups.com...
Thank you Dave for you insights. _____ From: Astrometrica@yahoogroups.com [mailto:Astrometrica@yahoogroups.com] On Behalf Of Dave Herald Sent: Thursday,...
Hello Hannes, Just so I am quite sure I understand. We you asking hypothetically out of intellectual curiosity? Or, are you suggesting you have, or could...

... While this may be roughly true (and it is an often claimed figure), it is a somewhat misleading statistic. It ignores the fact that the distribution of...
Hello all, I am experimenting with Astrometrica at the moment and I like it very much. I have had some previous experience with Astrometrica but that was more...
Hello Albert, I never send a measure with SNR < 6, It is a personal criteria :-) Greetings, Juan A.Henríquez http://atlante.org.es 2008/11/24 Albert van Duin...

There's a good paper by Herbert regarding this : http://www.astrometrica.at/Papers/PointSources.pdf You'll find why photometry needs more S/N than astrometry...
Yes of course, the highest snr is the best, and always still integration until the object move enough to be real. 6 is a SNR impossed tho myself for a good...
... I use SNR > 3 as a general rule of thumb, with the caveat that the object should be seen (at or near SNR > 3) on each of a string of at least three...
... Indeed John, this is essential. I always check the individual images by blinking to discount hot pixels. What I would love to see in Astrometrica is a...

Is there a way to switch "known object" overlay to "ON" for objects with a very short orbit? (5days arc, one month back). I had the case that "TheSky"...
