If I am taking long exposures for star trails how long should I wait between exposures to allow the sensor to cool down?

\$\begingroup\$ i'd think gaps between exposures will leave gaps in the trails. \$\endgroup\$– thsFeb 25, 2015 at 15:00

\$\begingroup\$ @ths I assume the intention is to have individual long exposures, not a stacked one. \$\endgroup\$– mattdmFeb 25, 2015 at 19:39

\$\begingroup\$ @mattdm i interpreted the original "two sub in long exposure" as stacked. but who knows... \$\endgroup\$– thsFeb 25, 2015 at 20:42

\$\begingroup\$ I've not used it, but StarStaX claims to be helpful in filling in the gaps in star trails from multiple exposures - markus-enzweiler.de/StarStaX/StarStaX.html \$\endgroup\$– OldGeeksGuideApr 14, 2015 at 20:23
