MagicLantern adds great features to Canon EOS cameras. Some enhancements are usable for astrophotography too. Or perfect for time lapses.
There is no installation for MagicLantern. Just copy it to your SD card and run the firmware update process in your DSLR.
Detailed instructions here.
Instead of using a remote control or a computer to trigger the exposures, MagicLantern offers a Intervalometer. No need anymore for additional equipment.
The BulbTimer works together with the Intervalometer.
Note: Exposure duration never should be higher than the interval!
Many other functions are great for daylight photography. I like the Zebras and Focus Peak (Why not by default? At least on a 70D… C’mon Canon!)

I do not want to miss MagicLantern anymore 😉
