I have automated the super telephoto zoom lens Sigma 50-500mm F4.5-6.3 APO. An electronic circuit controls the motor of the zoom lens and the exposure time of a DSLR camera.Together with an astronomical alt-azimuth mount, the system allows to make a live view optical zoom time lapse to deep sky objects (Deep Sky Time Lapse).After two years working on this project, I finally made a zooming into the Big Orion Nebula. The pictures were taken in Sierra Nevada (Granada/Spain) using a Canon 5D Mark , a Canon 450D modified, a zoom lens Sigma 50-500 mm APO, a teleconverter Canon extender EF x2 and the Meade LX80 mount.I would like to thank David Henarejos and Juan Antonio Albaladejo for their help in the electronic and mechanical workshop.Filmed by Isidro VillóMusic by Kirovent youtube.com/kirovent
