General Description

• UVES spectroscopy of planeary nebulae.  Slit to be centred on emission
   nebula which may not always be visible on slit viewer.  offset stars are provided
   where nebula or central star may be invisible, but may not always be needed where
   provided. Position accurate to 1-2 arcsec (there is sometimes a discrepancy between
   HST and USNO coordinates). Observations are of extended objects and can be done
   under very poor seeing.
  
  First exposure is always a very short integration. The spectra should show obvious
   Halpha lines, [NII] and [OIII] 5007A lines. Total OB lengths about 35 minutes plus
   overheads, for ~6 exposures,  with a range in exposure times to allow for both very
   bright and faint lines.   Finding charts are from HST images because the fields
   are often too crowded for the resolution of the dss2.
  
  A few observations end with a 5-sec integration. This is only used for cases where
  Halpha or OIII may be saturated in the first exposure. If they are not saturated,
   the 5-sec
  exposure may be skipped and/or discounted in the quality control.
