Exposure failure.

G'Day,

New to new forum and new to night photography. Based near Sydney Australia.

I am having a problem with new Asiair connected to Nikon D810, Redcat 51 lens, Asi 120MM Mini with the auto guidescope, and Star Adventurer

Using Ipad with all updates.

When trying to set things up and taking focus or preview I get the Exposure Failure notice.

Cant then take any shots or preview things.

Could someone please advise.

I had the same problem with a Canon 6D

If you have set the camera to manual and bulb, then use live view, before taking an exposure.

Check that your camera connect cable is working properly.
