new to CCD. suggested settings for 450 on SW80EDP

[gareth13]

Have just aquired a second hand atik450 and waiting impatiently for clear skies. What temperature setpoint would you recommend. I have previously used an unmodified canon 650D on a guided SW HEQ5 Pro mount, would I expect to use similar exposures (800 ISO).

For my 383L -10 to -15 is a good point as I can usually get this during most times of the year given the ambient temps here in the UK.

Once, in the south of france, it was -15 ambient!
