There are several variables to consider a larger telescope will look through a wider column of air. With good seeing a 12" scope will always be able to see finer detail Using my 150 triplet I have failed to see the red spot despite using different coloured filters. I always remember looking through the army telescope at Aldershot I believe a 10" F15 achromat and the colour of the red spot was quite brilliant but then I was 18 not over 60 as now. So perhaps another thing

to consider is how good are our own detectors in both eyes. My right eye is much better than the leftAnother factor over which we have some control is the eyepiece so everybody which eyepiece is best for planetary work?
