Re: solar filters

I use to have a glass filter (not on a AP telescope but I don't think this is relevant to the current comparison).
Then I moved to a Lunt solar wedge.
Here are 2 example taken with the same telescope (102 triplet APO):
glass filter imaging : http://www.rti-zone.org/astro/moon_sun/900gto/sun/spots_1582_1579_1575.jpg
Lunt wedge : http://www.rti-zone.org/astro/moon_sun/900gto/sun/Sun_partial_eclipse_2014_10_23_1.png

I think the image speak for themselves.
Regards, Rodolphe
