> Any suggestions for low light and long exposure celestial ? Well, then you're talking about the LX. However, if you're happy enough with making your long exposures with the "B for Bulb" setting, then I'd suggest possibly an MX or an ME Super, perhaps - both have fairly bright screens and do not need batteries for B (the MX doesn't actually need them for any shutter speed). Or, if mirror lock-up is important to you, then I'd suggest possibly an old KX. But, the LX "does it all"...
