Next: Data Acquisition Up: CCD Systems and Previous: The ST-4 . One SBIG upgrade from the ST-4 is the ST-6. ... This system also uses a motorized filter wheel made by Compuscope. ... The TEC for this camera head is similar in operation to that of the Lynxx, however the ST-6 allows the temperature to be set. ... Used together with the ST-4, longer uninterrupted exposures are possible. ... A function in the software allows the operator to combine several short exposures to create a composite image. ...

Next: Descriptor NFILTCAR Up: Instrument descriptors Previous: Instrument descriptors . The two most critical types of physical information needed about the filters themselves are (1) what are their transmission curves? and (2) does the instrument either regulate or measure their temperature? ... In addition, we need to know how many different filter-code fields appear in the data. Bearing all this in mind, here are the descriptors for filters: . ... Mon Jan 22 15:08:15 MET 1996 ...
