Very sad news. He really was a pioneer in the field of CCD imaging. I remember writing to him in 1997 when i started making my first steps into using CCDs and him writing back with plenty of useful advice. A great loss to the astronomical community.
Hi David.
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!

Chris – that image of Saturn is a fine example to the benefit of using ADC’s. Had this been taken without the result would be no where near as good with severe colour fringing and smearing. With all of the major planets skirting through the southern part of the ecliptic over the next few years it is an ideal time for getting an ADC and learning how to use it.
