Thank you to all (Francis) who helped me before with this issue of intervalometer inntervals.
I do Astrophotography timelapses with many different lenses, meaning many different shutter speeds.
Magic Lantern skips interval choices: 9,10,12,14,15,16,18,20,25,30.......
...
I need to have intervals that are one second longer than my shutter speeds...just enough time to process the picture.
Longer delays leads to gaps--undesired for my purposes.
Francis did make one that has 26,27,28,29, and for that I am very grateful.....
But I find that I need one second intervals all through-out the range, so that gaps don't appear in my startrails, timelapses, etc.
I post this here in case some other astrophotographers might agree with me....
...
I know it means more time to scroll through the numbers, but I think the fine tuned control would be worth it.
Thank you VERY much for all that has already been done....

I don't get... why not just setting intervalometer to some lower number?

And why opening a new topic for the same thing?

mSpider

Because it wasn't a feature request before--it was a question.
Now I know I would like to see this feature.

".....why not just setting intervalometer for some lower number"
Will it work properly if the interval is shorter than the shutterspeed?
Or do you just end up skipping frames and getting an uneven, jerky timelapse, like other intervalometers?
I thought the interval should always be slightly longer than the expsure Tv...

Why is there a warning that says "Jitter!" if you try to set the interval for shorter than the shutterspeed?
". If you put the intervalometer to 10 seconds, ML won't take longer exposures, no matter what. That's done to avoid jitter (i.e. get smooth motion in the timelapse)."
Maybe that doesn't apply anymore?

The shutter speed limitation only applies to bulb ramping.

Jitter means timing issue - you will no longer get precise timing, it will only shoot as fast as it can.
