hi Chris I have a Kendrik visual white light filter and it shows very good deatail of the sun spots and their surrounds, and also granulation is more easily seen than in my Thousand oaks glass filter .
But the nice orange colour in the TO filter is more pleasing then the Kendrik's white image .
One more thing I dont know why , but with the naked eye the Kendrik gives a white disk but when I photo the sun it comes out a purple colour , not a problem as the extra deatail seen more than makes up for that .
