Hi all.
In this new episode of "Finally checking how things work after many years …", I am looking into the Nikon D810A Exposure Delay Mode in combination with Mirror Up and Electronic Front Curtain Shutter.
For DSO astrophoto, I set the camera to M* for the built-in long exposure times, connect a "dumb" remote trigger, choose M-Up mode and enable the EFCS. It seemed sufficient for camera vibrations mitigation with a 3 - 4" manual* delay between mirror release and imaging, but I now found guidelines recommending the use of the EDM too, which mitigates rear curtain shutter vibrations?
Anyone with experience on the matter could shed some light if it's worth the effort for a focal length of 1020mm max and subs ~60" (tbc after trials)?
If I understand correctly, I still need to manually* delay by 3 - 4" between M-Up and EFCS, but then EDM would kick in for an additional 1, 2 or 3"?
*I gave up on my programmable wireless intervalometer and only replaced it with a very simple trigger, I need to sort that out … or try tether/remote control, or ASIAIR Plus, I guess?
