Wow SCT's can get a bad rap re image quality at times but ironically seem to produce many of the great planetary images, go figure

Mike, Ian is from the UK but I believe has been holidaying in Spain. With planetary imaging in particular, all other things being equal, the most critical aspect to success is the quality of the seeing, low alt and good seeing is preferable to high alt and rubbish seeing. Damain Peach, a year or so ago produced an amazing Saturn image at only 34 degrees alt. Of course, given good seeing the aperture does matter as it has a direct reationship to the frame rate that can be used. Bird posted a ripper Jupiter over on facebook yesterday with his latest 16". Also, regarding aperture, over the years I have seen many impressive results with the C-9.25 not sure but I think Damian cut his teeth in planetary imaging with a C-9.25 .

Agree on IR use for Jove - at low alt it really is the way to go!

Thanks very much John, IR & low alt certainly seems to work, often when RGB is impossible. It can still produce data, with regard to Jupiter, that can be measured by the JUPOS measurer's and be of scientific value.
