4.5", 6", and 10" Newtonian astrographs.
2 ST80s; ED80; 3 CCD cameras; 5 EQ mounts: all polished, tuned, and modified.
The rule of telescope features: aperture; equatorial tracking; or low cost. Pick any two.
Quote:3 seconds to vault across the sky is awfully fast for a satellite. I'd say 30 seconds is far more reasonable and done far longer than that.

Quote:A satellite in a Molniya orbit will be very slow moving at its apogee. These would certainly hang at near-sidereal angular speeds within 30 degrees of the pole - it's why a lot of ex-Soviet comms satellites were put into these high-inclination high eccentricity orbits, to allow a long "hang-time" over the USSR's land and to allow communications in the polar regions that are not possible with geosynchronous satellites.As for whether these would have a strobe effect? I don't know enough to be able to answer.(as an aside) The planetarium software "Home Planet" can give a POV view from a satellite - it's fun tracking a Russian satellite in a Molniya orbit as it reaches perigee.
Quote:But when I look in Stellarium, there is this obvious huge band of geosynchronous satellites, and I have never been able to see any of them. I thought it was something about the angle of the sun and so on, but these posts have got me thinking...Is it easy to see polar satellites because they are often in LEO (like 400km up), but hard to see geosynch satellites (or Molniya at apogee) simply because they are so much further away (like 35,000km)?I guess that's pretty obvious, but it's the first time I've connected the dots.
