Wesnikon - does your intervalometer support the electronic shutter?

If so, which model are you using.  I would like to use the electronic shutter for AP as well.

I also just downloaded the trial edition - will have time tomorrow to work with it.

I will let you know if I can get it to work.

The one I use is an Ayex AX-5, very similar to this one here - https://www.amazon.co.uk/Timer-Remote-Shutter-Release-Canon/dp/B008BZKKA6 (can't find this brand on amazon.com). The catch is, in order for it to work live view must be activated, which obviously would suck for AP (battery drain, heat). I'm not sure if the Nikon Firmware (and the API) would support using the electronic shutter with just the mirror being up (and no live view), but from a technical viewpoint I can't see why not. Maybe live view is needed for the mechanical shutter to open without triggering an exposure, who knows?

I don't know about Nikon, but with my Canon, when in LiveView mode, you cannot control when the sensor is read out. It happens as fast as the firmware can make it happen.

So, why do you want to avoid use of the mechanical shutter for AP? I hope that your reply is not to avoid shutter bounce, which is not a problem with long duration, deep sky imaging.

I wanted to avoid constant shutter use - 15 sec exposures for an hour seems like a lot of wear and tear on the shutter.

 

That is nothing actually, these shutters are capable of taking much harsher beating than that.  You should never worry about that.

The topic says LiveView, but you seem to be talking about running a capture plan (not LiveView) with 15 second exposures.

If Nikons work like my Canon, the shutter is always open during LiveView.

I am confused...Can you explain?

Thanks.

Nikon work just as Canon in that respect.

But, in LiveView the shutter stays open while LiveView is on. In effect, there is no shutter in LiveView. Each LiveView frame is an exposure of just a few milliseconds. The shutter cannot be used for this. If the shutter were being used to separate LiveView frames it would cause a noticeable high-speed chattering sound as it opened and closed several times a second. You should be able to test if this is so by taking the lens off of the camera, turn on LiveView and look into the camera at the sensor. Do you see the shutter opening and closing at a high rate? or at all?
