I was thinking of bringing my Jupiter data on a dvd and giving copies to anyone that wants to take it away for practise. Are you likely to have a dvd writer there DP, or anyone else? I've only got a CD writer in my laptop.
I wanted people to see the raw data so they realise how awful it looks - extremely short exposures give frames with lots and lots of noise, but then this noise magically vanishes when you stack a few hundred of them. I think a lot of people are trying to capture raw frames that look "good", but this is a mistake (imho), and the long exposures needed to do this are introducing blurring that can't be removed.
On jupiter I'm using exposures around 30ms, and through colour filters this makes the planet very dim.
