Hi Andrew , I have owned a 1000 oaks glass and Kendrik solar filters in the past and now have the Lunt wedge and I concur with Morton here , the detail seen is seen easier and is more contrasty , especially the sun spots at high powers 150x + .
The only thing I miss about the nice 1000 oaks glass filter is the lovely orange disc these give , looks more natural ? but the Kendrik showed more surface granulation .
Brian.
