The scheduling information is one of the most important configurations for your TASKs. This is a description of the data entry necessary for this particular part of a TASK definition: see >>How to create a new PROJECT<< and >>How to add a TASK to a PROJECT<< for the first part of this process.
First, select the "Scheduling" panel
You can now add a whole series of different scheduling constraints, based both on the properties of your object (e.g. position in the sky, time of some particular event) or via relationships to other TASKs and objects (e.g. not too close to the Moon).
NOTE THAT THE MORE CONTRAINTS YOU ADD, THE MORE DIFFICULT IT WILL PROBABLY BE TO ACTUALLY PERFORM YOUR TASK!
There are a wide variety of different scheduling patterns available, ranging from a simple single shot to complex phased observations, each with its own set of parameters and with its own type of impact on the observability of your object.
The set of scheduling constraints that EVERY observation has is listed at the bottom of the page: the closeness to the Moon and the altitude of the object in the sky. Use the former if your object is faint and might be hard to see against the brightness of the Moonlight sky. Use the latter to change how deeply the telescope is allowed to look into the dust and haze of the atmosphere; since the seeing (image quality) is directly affected by the amount of atmosphere between the object and the telescope, choosing a low altitude means that the image may turn out to be of lower quality (on the other hand, it might be taken at all!).
The very simplest possible schedule is.... practically none: "OneObservation". This means that the telescope will simply look at the object if it is up and take a series of identical exposures (e.g. maybe just one).
There are many other types of scheduling constraints and you can combine them: to add another constraint, press the "Add new scheduling button" and continue.
For more information on the more complicated scheduling patterns, see the "Art of Robotic Scheduling" section of the Help topics.
