I created a little web-app that calibrates a digital camera's time delay and lets you know exactly when it is that your camera recorded the time. For my Nikon D70, if I do a 2 second exposure followed by a 2 second noise reduction dark frame step - the time is the end of the original exposure (and before the 2 second dark frame). This is different than Marco's camera which records the time at the start of the exposure. Unfortunately my camera only stores the time to a 1 second resolution - no tenths of seconds (or finer) so this whole feature is kind of useless for satellite timing. Better to trigger the camera with my laptop at a very accurate time. I already have software to do that. Here is the application- it's very simple - basically take a picture of the screen at the website below. Try it out even if you don't have a digital camera and you'll see how it basically works: http://gr5.org/calibrator.htm Feel free to steal it and post it on your own website. - George Roberts http://gr5.org ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
