Hi all , Following last weekends double transit , it seems that one of the major problems is accurately time stamping each video frame. The GPS cordinates can simply be noted down at the site , but with transits ,and satellite passes time accuracy is a must. Today I have spent some time exchanging mail with Peter Katreniak . Peter is the author of K3CCD tools , a software programme for driving and processesing astro video. Peter recently added a time stamp facility to his sw , which , during all the hubble bubble of the Venus solar tranist , many of us overlooked. It turns out that it is possible to datesatmp collected video frames in the format : hh:nn:ss.lll , d.m.yyyy which gives accuracy to about 250 msec. You can see Peters summary here: http://www.pk3.org/Astro/index.htm?astrophoto_webcam_timing.htm K3CCD is a brilliant capture and processing tool , with everything you need , plus more ! Set up of the time stamp can be a bit fiddly , so if you are having any probs , drop me a line. Best wishes, John ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
