All Sky Camera Project - BYE vs APT

Recommended Posts

I'm thinking of using an old Canon DSLR for an automated all sky camera project. Would either APT or Backyard EOS enable me to programme only shooting sessions during hours of darkness? I.e. starting and finishing shooting at certain times of day?

Since the camera could be unattended for several weeks- I don't want Gigabytes of daytime skies to clog up my HDD.

I have started to work on such option. It will be great if we continue to discuss this into my forum. I don't want to violate the rules here :)

In short will combine the existing Loop feature with new Schedule options - dark time, astro night and night...

Hi LJ99,

Thank you! After short analysis it happened that I already have most of the needed parts - plan looping, scheduling and darkness clock :) I hope to finish the whole functionality today... There will be a small update in the next 10 days so look for the automation in it ;)

Here is how the interface looks:

Hi James,

At this stage the end option is a bit awkward :( If you select Loop # to be different than 0 and use one of the new scheduling options APT checks the condition after every round. For example if you select DSD APT will stop next loop when DSD is over... Hope that it is good enough till I find time for better solution :)

If the Loop # is 0, then the loop will continue on the next night ;)

They all come from the Darkness Clock :) All that is needed is the site coordinates and timezone. APT takes care for the rest ;)

DSD is the time between the end and start of Astro twilight and without Moon.

Astro night is  the time between the end and start of Astro twilight no matter the Moon

Night is the time between sunset and sunrize
