I’ve captured it many times. You’ll need good seeing for a start (as Martin mentions.) With thousands of frames averaged under good seeing it should show up as a faint spot (at least it does in the 14″ scope.) Exposures of 1 second or so will certainly show it up as its not really that faint. Using an R or IR filter will help with Saturn from the low altitude we have in the UK. You already have an ADC which is essential. Its just making sure collimation, focus are good….and then catching steady seeing. I do warn you though – at just 17deg altitude you may be in for a long wait!
