I think the ability to do long exposures depends on how much thermal noise the chip produces, and how well it can separate noise from signal.
Dunno the current tech on any particular camera, but I know astro photographers have long embraced digital. However, I think their devices have some serious cooling systems. -- Not that they need it much here, though... :-) Jostein (happy about the last two days' whiff of mild air; only minus ten now) ----- Original Message ----- From: "J.
