The STELLA robotic system is very powerful - but also very complex. "Observers" used to a manual or remote use of a telescope may find it difficult to adjust to the idea of being forced to tell an otherwise stupid computer what one would like.
You will probably find it easier to handle the system if you separate your PROJECTs and/or TASKs into two types:
- special purpose PROJECTs/TASKs designed to do a particular thing which, when finished, probably aren't used again; and
- general purpose PROJECTs/TASKs which, in principle, could be easily recycled/reused.
An example of a special purpose PROJECT would be a campaign to observe a particular event, e.g. "Supernova 2014g": the purpose for the PROJECT is obvious, there is only a single target and hence probably only a single TASK. Once SN 2014g has faded, there's probably no reason to go back to the PROJECT, at least for the purpose of ordering new observations.
An example of a general purpose PROJECT would be "My favourite colour images". There's little point in using multiple TASKs for this project, since they will probably all be the same except for the details of the individual OBSERVATIONs: one could use a single TASK called "Colour Imaging" to produce a whole set of observations, all of which would be collected under this PROJECT, but each with it's own target and exposure times. Take a look at F. Hessman's "Nice coloured pictures" PROJECT designed to do exactly this.
