I'm not allowed to share the images of course. We do use astrometrica to reduce the images. <br><br>I'll try to gauge over the next few nights how many there are. The Catalina sky survey images are much better than some of the other ones that are received. I have a feeling also that the Geo belt imaging maybe finished looking at what's coming in these last few sets.<br><br><br><br><br><a href="">Sent from Yahoo Mail for iPhone</a></div><div id='yahoo__original_message' class='yQTDBase'><br><blockquote style="margin:0 0 0 .8ex; border-left:1px #ccc solid; padding-left:1ex; ">At Nov 3, 2014, 4:35:54 PM, Marco Langbroek<'<a href=""

For some reason, although they have usually avoided the Geo belt, I'm getting lots of images this campaign with what appeared to be satellite tracks as artifacts on the images. The FITS files are annotated with the time of observation and exposure time, so I'm assuming these would be useful to check for any satellites that were caught. I can integrate these images into Obsreduce if I remember
 correctly, or I can manually Measure the positions at the beginning and ending of trail. My question is to the group, does this seem worthwhile of the time involved?<div><br></div><div>Brad<br><br><br><br><a href="<a shape="rect" href="" target="_blank"></a>">Sent from Yahoo Mail for iPhone</a></div></div><div id='yahoo__original_message'></div><br clear="none"><br clear="none">Given that it are FITS, it is best to actually astrometrically measure the <br clear="none">trails with Astrometrica, not obsreduce.<br clear="none"><br clear="none">I usually don't bother to measure satellites in our Konkoly asteroid survey <br clear="none">imagery: there are simply too many...<br clear="none"><br clear="none">- Marco<br clear="none"><br clear="none">-----<br clear="none">Dr Marco Langbroek  -  SatTrackCam Leiden, the Netherlands.<br clear="none">e-mail: <a shape="rect"
