Abstract:	Non-filter eclipse polarimetric observations of E-limb Hα-prominences made in 1994 by a portable corona-graphpolarimeter are used to estimate expected accuracy for polarization degree and polarization direction determination. The main advantage of the instrumentation was to put a rotating polarizer in the plane of the Lyot stop. IDL software and Stokes-vector analysis applied to 24 digitized images of Hα-prominences of 1994 resulted in an accuracy of 2% for polarization degree and 2circ for polarization direction. Prospects for eclipse polarimetric researches of prominences are discussed when colour or black-and-white film, or a conventional videocamera, are used as a detector. It is concluded that filter prominence observations could lead to an accuracy of less than 1% and 1circ for polarization degree and direction respectively.
