Spring in 4K - Canon 60D and ML 2.3

[Gabas]

Hi Everyone!!!!

This was my third timelapse ever, and my third timelapse with Magic Lantern!!!
I loved it... And so, like the third time it's the charm, I shot all photos in 18MP and edited it in 4K.
The final output was in 4K but I've uploaded a 1080p version to Vimeo, of course.
Feel free to give some inputs!

Canon 60D
Tamron 17-50mm f/2.8 (f/5.6 used)
ISO 320
3 shots for second. 600 shots per day. 4 days shotting... 2400 shots overall.

I'm wondering how do I use the bulb ramping effect? on dark clean sky nights... Is there any tutorials out there teaching
to do night time-lapsing?
That would be awesome!!!!
Thanks guys!

Cheers!
