Is there an astrophotography intervalometer script around somewhere? Wanted to check before attempting to write one. Specific features:
1) Set MF to infinity.
2) Set manual exposure.
3) Multiple use of custom timer. Since the camera will be in manual mode, no need to set exposure after each shot. Number of exposures required will determine how many shots to specify for custom timer and how many times to loop the timer.
4) Ensure that dark frame noise reduction is off at the beginning of custom timer sequence. At the end of each sequence, turn DF noise reduction on and take dark frame (this will take two shots at the given shutter speed).
5) Possibly increase or reduce shutter speed after each sequence (ensuring not to exceed slowest time limit).
6) Possibly reading sensor temperature at the beginning and end of each sequence to determine if to take the dark frame (if the temperature appears to be deviating at bit). (Collaborative build only feature).
