Astrometrica users may be interested in the paper 'A method of determining V magnitudes of asteroids from CCD images' by Richard Miles and Roger Dymock...
The paper is indeed a very interesting method but both authors uses a CCD camera with an interline chip on it ? As long as I know, the interline chips used on...
Excellent work by Richard and Roger, congratulations to both. I've just had a first read of the paper and seems wonderful to me. Of course we'll have to care...
Thanks Joan and Juan for the compliments - Herbert and I worked for 2 months on introducing the photometry option into Astrometrica. One word of warning -...
Roger, Other than changing the "Photometric Limit" setting in the Residuals block, and checking the "Magnitude to 0.01 mag" box in the MPC Report block of the...
Gerald, You are quite right in pointing out that for Photometry in the Program tab you need: 1. Residuals, Photometric Limit:> set this to say 0.2 mag 2....
Thanks Richard. This is great information. I've been pretty stingy with my Aperature Radius settings, especially since the Milky Way is high right now,...
Hello Richard, Nice to read you again ! Still there are differences .The full frame chip (KAF 1602E) installed in the camera we uses at Tacande Observatory has...
... You should not report random observations of minor planets with magnitudes to 0.01 mag. That feature is intended for the reporting of photometric...
Hi: I've had this program 5 years ago, now I have a new computer and my login is lost, as my configurations. For the Login maybe the moderator can help? I...
... Make sure you have specified a valid e-mail address in the program settings of Astrometrica. The ftp-server at the MPC requires to send your e-mail address...
Hi: I performed a plate solution for one of my images and was able to use over 800 stars in the solution with good residuals. Is there a way to allow...
Astrometrica loads the MPCORB.dat file with the heliocentric orbits of minor planets, it also handles COMET.dat with the cometary orbits, as far as I know...
... Yup. And even if Astrometrica would import some elements file for artificial sats, there is no chance they would get plotted anywhere near the true...
... Probably only JPL HORIZONS can tell you where it is supposed to be on your images. Generate ephems with short step size such that the epochs of your frames...
... Not true. DASO page: http://www.cfa.harvard.edu/iau/SpaceJunk/SpaceJunk.html will happily return ephemerides for LCROSS at 1-min intervals for a specified...
I am pretty new to astronomy. I picked up a mid 80's Meade DS-10 a year ago. Within a few months I put it on a Atlas EQ-G mount. And picked up a Orion Star...
BP_190709/ Dear astrometrica members, I'm searching for practical hints to avoid a big mis-invest to construct a full neo-station just on the top of my house...
Hello Donny, ... there is a solution: Write down the beginning and exposure time of the image and enter the time of the middle of the exposure manually within...
The scope (10" f/4.5 equatorial Newton) may be adequate for detecting asteroids up to magnitude 15 or 16 (based on my experience with 10" LX200 and 11" C11). I...
It is possible to use images taken with a DSLR, but it's not easy. The time stamps on the DSLR images are useless because they cannot be adequately synced with...
... Under dark skies, you can certainly go much deeper with a 10" if you use an astronomical CCD camera. I am not sure how deep you can go with a DSLR, but at...
Thank you for all the information. I guess I can get started with the Sony DSLR with the brighter ones to get my feet wet. Then once I gain enough funds to...
Hello, I have downloaded an evaluation version I am about to install and would like to solicitate any suggestions for first time setup you all might have. I...
Hello Herbert, Hello all Only a basic question, Herbert. Are the coordinates given by Astrometrica corrected of the effect of nutation and annual aberration? A...
