Maybe I just do not know how to set it up, but it seems that SGP will not allow one to set up (as a target), a set of darks to be done before a target that contains a light. It tries to do things that make no sense for darks, such as insisting that the guider be running.
I also tried this as part of a target containing lights (as the first item). It still insists on running the guider. Taking darks while waiting for full dark or the object to be high enough (in which case guiding might not be possible if the object is blocked) is a very common procedure. How can this be done without unnecessarily running the guider (or can it)?
Am I missing some setting or procedure or is this not possible?
If not currently possible, consider it a feature request. Basically to treat darks the same before a set of lights as it treats them after a set of lights and not try to or expect to be able to guide or to be in any particular sky position.
