10. Suggested Exposure Times For Calibration Spectra
... Flats : Properly exposed flats over all echelle orders require a two-step process. Flats are taken both with and without a CuSO4 (aka "blue") filter in the beam. ... Suggested exposures are 7 seconds ("red"; no filter) and 240 seconds ("blue", CuSO4 filter) yielding S/N values of ~480. The filter for "blue" flats is listed as "blue" in the Config window in Echelle control under Remark. ... Exposure times for objects can be derived from the following plot: . ...

13. Optical System
... The three optical trains for the cameras, and the pupil reimaging system, are mounted on a wheel, accurately driven by an external motor. ... The low-resolution spectroscopic mode uses the wide field camera and a suitable set of grisms and order sorting filters that are inserted in the parallel beam after the pupil. ... One of the five grisms can operate at four different orders, depending on the filter selected on the first filter wheel that acts as order sorter. ...

15. FORS Sec Std and Abs Phot Project
... The first step to improve the FORS calibration is therefore to obtain data to allow a computation of the illumination correction across the field. ... Another limitation on the calibration accuracy has been the brightness of the Landolt standards which have forced the use of extremely short exposures introducing small but non-negligible shutter-time errors and also resulting in a very small number of useful standards per frame. ...

18. Nove in M31 2, 1998
Nova 1998 2 in M31 this image of the second Nova in M31 in 1998, was made from 38 exposures of 45 seconds integration time. It was made at September 21, 22h 20m UT. Telescope was a CG11 at f/6.3, no filters were used. The long list of processing steps caused the artefacts at the overexposed center of the galaxy and in many of the brighter stars. During the exposures thin clouds covered the sky but the CCD cuts through them, allowing me to obtain this result. ...
