Thanks Peter. I think I might go down that line. I have a Sony Hi Def Handycam with still picture capture on SD card as well as Hard Drive Recording. It is nice and small and takes great quality video. Low light seems to be pretty good and it also has IR. I just don't want to carry too much stuff as I will have a telescope as well. I have a few internal flights in the USA and you can't carry much baggage without Excess charges. So many different reports on what you can get images with. I am still not fully sure whats best. Knowing me, at the end I will grab the Video Cam and the DSLR and every other camera know to man.
I was also thinking of getting a cheap 35mm slr to take the pictures and then just leave it behind... It can all start doing your head in
Thanks
Mardy
