I have some avis of saturn i took last night, but when i put them through vdub to get them as individual bmps, they lose a fair bit of quality (enough of a difference to lose the rings). If i load them straight into registax, they have good quality, but theres multiple passes (i'm yet to get tracking) and it can't allign properly. Is there any settings in vdub, or a similar program which will allow me to keep the detail and get a sequence of bmps for ppmcentre?
