Hi all....
I'm looking at a solar scope, but am a little confused about what some of the nomenclature used to describe them means....
Can anyone offer explanations on some of these terms??
double stacked
pressure tuning
etalon
blocking filter

Any buying advice around $2k?? Would mainly be for casual visual observing, but would want to be able to image through also at times.....

TIA
Lee
