Just some advice required on which would be better. Will use it for guiding through an ED80 or similar and also for AVI of planets. South Australian shop advertises Phillips ToUcam ProII PCVC840K as standard but then they say modified for long exposures for $275 or SPC 900NC also modified for long exposures for $285. Is one better than the other. Any advice would be greatly appreciated.
Thanks
Mark.
