For serious observers/imagers who do not wish to compromise image quality, I strongly recommend a Baader Neutral Density (ND) Solar Filter. The bigger one (green frame) is an ND 5.0 for visual use, while the smaller one is an ND 3.8 intended for photographic use only. These are available locally and abroad. Got my ND 5.0 in 2010 and the ND 3.8 early this year.
