These are observations obtained with the Canon EOS 70D and a Samyang 85mm F/1.4 lens. Exposure times of 10s at 800 ISO were used. Pixel scale is 9.84 arcseconds per pixel and the field of view is 15 by 10 degrees. On the second night the camera was mounted on the NexStar goto mount for testing. This worked remarkably well and should allow me to scan significant parts of the sky for high altitude objects. Conditions were excellent on both nights. 32706 08 010A 4171 E 20130930200218057 27 25 1858333+540925 17 S 32706 08 010A 4171 E 20130930200234041 27 25 1858632+540677 17 S 32706 08 010A 4171 E

4171: 52.8344N, 6.3785E, 10m (WGS84) ------------------------------------------------------------------ NOTES: ------ (1) Recovered USA 200 [32706/08010A] and Unknown 090126 [90083/09526A], which had not been seen for some 70 days. 90083 was flashing making it hard to estimate the center of the track. Hence, its positions will have some scatter. (2) Object 99069/13772A is an unknown I saw on the 29th and captured again on the 30th. It is steady in brightness and comparable to the brightness of USA 200. Mike reported it did not seem to match anything we've logged before. This is my estimate of the orbit, which is very close to the values expected for an object in an operational Molniya orbit.
