The reason that I used the ISS was that my videocamera isn't a low light camera. I could barely see stars to mag 2. Tonight i'll try to catch a ISS pass with Altair and Rasalhague as reference stars. Huge FOV, so it will not be that accurate. Well it's going to be fun anyways. :) > I have found that good calibrators are the Iridium satelites.

Ok, I'll remember that when I get a low light camera. :) >> Doesn't Denmark have some sort of shortwave time signals similar to the >> USA's WWV?? > > Yup, DCF77 from Germany will also be available from Denmark.

What I could test yesterday with my videocamera was that the time readings from Heavensat. The second part changed at frame 15 +- 2 frames. That's 80 ms uncertainty, so I guess I'll stick to a DCF77-clock or my handheld GPS until I find a better "show the clock" program. > - Marco -- Daniel Trads Fredericia, Denmark Postion: 55.568N, 9.728E, 20m ASL, Cospar 5055 ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
