Observations at Tuorla Observatory
	Telescope configuration which is used at Tuorla Observatory to witness the event. Images are projected by two secondary telescopes. Used eye-pieces are Ramsden type. In this type of eye-piece there aren't any cemented elements which can collect heat and eventually break up.
	Simulation of projected image with low magnification eye-piece.
