Observation of NEOs Having High Apparent Rates with Mobitel Telescope

When NEO approaching to the Earth close then 0.05 AU its apparent rate begin increasing and magnitude begin decreasing rapidly by hyperbolic low. When small NEO close to the Earth it is observable for the small telescopes, but after going away it may become unobservable for the most of telescopes. Observations of NEO on short distances are valuable for the orbit determination. Increasing of NEO's apparent rate causes limitation of exposure time in case if telescope observe in star tracking mode. So the telescope's limited magnitude can't be reached. Not all telescopes are able to track NEO with two axles. Frames obtained while NEO tracking contain stretched images of stars. Stretched stars images and telescope movement with two axles while exposure time cause accuracy decreasing. An original combined observation method is used in RI NAO for observation of NEOs having apparent rate >10″/min without any telescope mechanical tracking. There are two telescopes in RI AO that can observe NEOs, fast moving near the Earth at distances 0.0002 ÷ 0.05 AU.
