Each Observer and Observer Group can be given certain privileges that provide access to the observatory's capabilities which are greater than available to the default observer.

An observer's privileges are result from the sum of their own privileges and that of the observer group in which they are assigned. The combined privilege value is the sum of all the individual privilege values given below, which each have a unique binary bit set.

Privilege Name



No Authorization


The observer has no privileges. This has the same effect as the observer not being in the “observers” database at all. It is the default setting when a new observer requests authorization. It can be set when an observer has completed observations, but are no longer allowed to use the observatory for new requests.



The observer has access to communicate with and use the observatory with basic privileges. In particular, up to 3 observations can be submitted to the Observation Request queue at a time and a maximum exposure time of 5 minutes.

Larger Queue Limit


The observer can have up to 15 pending requests in the Observation Request queue (instead of the basic limit of 3).

Longer Exposures


Exposure times, per filter, can be up to 15 minutes in a given filter (instead of the basic limit of 5 minutes).

Add Objects to Database


The observer can use the #addobject command to add new objects to the observatory’s object database.

Repeated Observations


The observer can use the ‘repeat=yes’ option of the #request command. This allows a successfully-completed observation request to be automatically re-requested to the Observation Request queue.

Special Observations


The observer can use the ‘special=’ option of the #request command to make observation requests in more than one filter and/or have finer control over the individual exposures that combine to make an observation.

Observation Priority


The observer can use the “priority=” option of the #request command to alter the priority of the request higher or lower than the default.

Time Series Observations


The observer can use the “special=” option of the #request command to make time-series observations of an object (eg. for variable stars, exo-planets, etc.).

Live Operation


This observer can use advanced commands to manage the observatory’s operations or operate the telescope during live operations. It is restricted to observatory staff who need it.

Super User


Observers with this privilege are granted all other privileges above. It is restricted to the observatory’s director and other staff who need it.
