I want to use my Nikon D90 camera for long exposure astrophotography.
For exposure times longer than 30 seconds I bought a DSUSB-IR which should operate similar to the DSUSB.
When I connect this setup to SGP, shooting exposures shorter than 30 sec. is not a problem.
But for exposures longer than 30 sec., and using the DSUSB-IR in bulb mode, I run into a problem.
In order to use IR, I have to manualy enable the IR sensor of the D90.
But when I try to start an exposure, either by a sequence or in Frame and Focus mode, SGP disables the IR sensor on the D90 at the moment the exposure should begin.
I can see, by the camera of my cell phone, that the IR led lightens up at the start of the exposure but with a disabled IR sensor on the D90, nothing hapens.
SGP is still thinking that the exposure has begun.
It lights up the IR led at the and of the exposure time but freezes at the download from the camera, since there is nothing to download.
The only thing that can be done in this situation is to end SGP, no other control is functional anymore within the program.
This seems to be an SGP problem since this same setup does work with Maxim dl.
How can this be fixed?
I am using SGP verion 184.108.40.206 on Windows 10.
It is not Windows nor PC related because I encountered the same problem on a Win.7 PC.
